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.

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.
