Normal unbranched pentane is an alkaline with five carbon atoms with the formula C5H12. Pentanes are commonly used as components of some fuels which are often employed as speciality solvents in the laboratory. Normal pentane is the most important isomer of pentane. In appearance is a colourless flammable, water-insoluble and a very volatile liquid obtained from petroleum by distillation.

In the industry pentane is used mainly as a primary blowing agent in the manufacturing of polystyrene foam. It is used because of its lower cost compared to other chemicals, low boiling point and relative safety when in use. Geothermal power stations have been using pentane in binary cycle systems wherein warm geothermal water is brought to the surface and passed through a heat exchanger containing pentane. Because of its much lower boiling point compared to water, the pentane heats up the binary fluid causing the turbines to spin. The advantage out here is that the pentane can be re-used once it condenses which is why it is pumped back into the system. Normal pentane is also used as a solvent and in varied industrial applications such as pharmaceutical, petrochemical, paints & coatings.

In terms of physical properties, pentane shows a boiling point in the range of 9 to 36 °C which is the result of its more branched isomers. Pentane isomers also burn with oxygen breaking down into carbon dioxide and water.

Global Trust Enterprises FZCO is a leading general trading company in the Middle East. They are the supplier of choice when it comes to providing quality industrial chemicals including normal pentane to the petrochemical industries in the Middle East and North Africa Region.

Propionaldehyde is a colourless liquid with a fruity odour that can be slighty irritating. It is an organic compound (CH3CH2CHO) which is composed of a saturated 3-carbon aldehyde. Propionaldehyde is also an isomer of acetone which is industrially produced by the process of hydroformylation.  The hydroformylation is conducted with the combination of carbon monoxide and hydrogen along with ethylene with the help of a metal catalyst.

Propionaldehyde has been used in a condensation reaction with methanol which results in trimethylolethane which is an important intermediate for the production of alkyd resins. Condensation of propionaldehyde with tert-butylamine gives CH3CH2CH=N-t-Bu, a three-carbon building block used in organic synthesis. Deprotonation of this imine with LDA produces CH3CHLiCH=N-t-Bu, which in turn condenses with aldehydes.

Propionaldehyde in the chemical industry is used in the manufacture of plastics, in the synthesis of rubber chemicals, and as a disinfectant and preservative.

Global Trust Enterprises has been supplying quality propionaldehyde to many industries in the Middle East and The North Africa Region.

A Brief On Triethylaluminium (TEA)



Product Identification:
CAS: 97-93-8
Molecular Formula: C6H15Al
Molecular Weight: 114.16 gm/mole

Physical and Chemical Properties:
Appearance                      : Clear, colorless liquid
Aluminum Content, %       : 23.0
Purity, %                               : 94.0
Tri-n-Propyl Aluminum,%    : 0.7

Triethylaluminium (TEA) is an organoaluminium compound, composed of a dimeric structure ( Al2Et6 ) which is bridged by a pair of ethyl groups and 2 five-coordinate carbon centres. In appearance TEA is a colourless volatile liquid which ignites immediately if exposed to air; which is why it is stored in stainless steel containers as a pure liquid or in the form of a solution as a hyrdrocarbon solvent such as heptanes. 

Its efficient synthesis makes triethylaluminium one of the most available organoaluminium compounds. TEA can also be generated from ethylaluminium sesquichloride (Al2Cl3Et3), which arises by treating aluminium powder with chloroethane. 

In terms of reactivity, triethylaluminium reacts violently with water to form a flammable ethane gas but at the same time has no significant reaction to commonly found materials.

Mainly used as a co-catalyst in the synthetic polymerization of HDPE and LLDPE, Triethylaluminium has been utilized in the industry as an intermediate in the production of fatty alcohols, which are later converted into detergents.  As a co-catalyst it forms an essential part of the catalyst system used as activator to accelerate the reaction which produces a polymer. Its highly pyrophoric properties make it a great pyrophoric agent which is the reason for it being used as a rocket engine ignitor. Its high pyrophoricity also makes it ideal as a fuel to be used to power rockets but only as a mixture with triethylborane.

Global Trust Enterprises FZCO is the most trusted name when it comes to the supply of industrial chemicals in the Middle East and the North Africa region. They have been supplying quality Triethylaluminium and other industrial chemicals along with equipment; their spares and lubricants for their clients in the steel, aluminium, and the petrochemical industries in the Middle East.

Sulfolane - A Reusable Solvent With Numerous Applications


Private transportation is not a problem today and that is because fuel is cheaper and has gotten easier to produce and extract. Almost every second person around owns a vehicle, even two or three at times and this again is not because he can afford the cars, but rather because he can afford to fuel them. Fuel then becomes one of the main factors behind an individual’s decision to purchase a vehicle. As of today, the prices of fuel and gas witness great shifts, depending on the amount of raw crude oil that is extracted all around the world.

Technically if there was no fuel, cars would run on electricity, but this would never happen since cars were invented to be driven by fuel. Even in the earlier days, running an automobile on petrol proved to be more efficient as compared with running it on steam or coal, not to mention the inconvenience that the latter two provided. Owing to the advancements in technology, today petrol and natural gas are the two primary agents employed in fueling the world.

What makes petrol and natural gas cheap enough to be used by the common people on a daily basis is the process that is used to extract them from their crude form. Without this process, it would be extremely challenging to yield them at such economical prices. Solvents help get the job done easily and in the most economical way possible. Sulfolane is one such solvent that literally drives the refinery business. Sulfolane is used to purify natural gas and petrol, eliminating the impurities and making the agents ready for use. Sulfolane was developed and widely implemented in the Sulfinol Process introduced by Shell in 1964, which removed H2S, CO2 and COS from natural gas making it purer and widely available. The main advantage of using Sulfolane previously and even today is that it is highly effective in purifying or separating aromatic hydrocarbons during liquid-liquid extraction. Having properties that allow it to be miscible in hydrocarbons and water enables Sulfolane to be used to purify a large variety of hydrocarbon based mixtures. Another characteristic that Sulfolane possesses is that it can be used in lower solvent/feed ratios making it cheap, effective and reusable because of its highly stable structure.

Sulfolane appears to be a clear, colorless liquid commonly used in the chemical industry as an extractive distillation solvent or reaction solvent. It is also used as a reaction solvent for the preparation of aromatic sulfonic acids, pyridines, isocyanates and medicines. Having such an efficient and productive solvent will certainly enable most refineries to cut down costs, but that entirely depends on the quality of Sulfolane supplied.

The Billion Dollar Polyethylene


Polymers have been one of the most widely used materials in the industry today. They have been in use because of their customizable properties and flexibility which allows them to be molded into any form or shape and engineered to withstand even the most demanding conditions. Polymers also have a longer lifetime and do not break apart easily when subjected to stress. When polymers are reinforced with multiple fine fibers of glass, they yield fiber-glass which has repeatedly been used for demanding applications in the marine industry.

Today, polymers are used in the manufacture of endless applications. The most widely used application of polymers is in the form of polyethylene or polythene, which people commonly refer to as plastic. Plastics have varied applications across different industries. They are used in the creation of commonly used plastic bags used for packaging and holding goods, and in the form of synthetic polymers to make Bakelite, Neoprene, Nylon and Xylethon. These applications use different forms of polyethylene which serve different purposes in the manufacture of different goods.

Polyethylenes can be classified according to their density. One of the most commonly used types of polyethylene is the Linear Low Density Polyethylene or LLDPE. Although Linear Low Density Polyethylene is very similar to Low Density Polyethylene, its linearity is what makes it different from the latter. This linearity is the result of a different manufacturing process which utilizes lower temperatures and pressures during the copolymerization of ethylene. This results in a more standardized molecular weight distribution, which renders it a linear structure thereby giving LLDPE more tensile strength and enhanced resistance to tear, hence making it a better alternative to Low Density Polyethylene.
In terms of appearance, LLDPE is an off-white solid mainly available in granular form and although it gives out a wax like odor when heated, it is not explosive and does not oxidize.

Linear Low Density Polyethylene is successfully replacing LDPE as a material of choice to work with. LLDPE is thinner and also offers better stress resistance, which is why LLDPE is used to produce plastic bags and sheets (where it offers lower thickness compared with LDPE), plastic wraps, stretch wraps, children’s toys, lids, all types of piping, containers, covering the cables and in flexible tubing. Having such a wide variety of applications has generated a worldwide revenue surpassing billions of dollars.
