Mono Ethylene Glycol – Fibre

CAS :107-21-1

Mono Ethylene Glycol also known as MEG is a clear, colourless, virtually odourless, and slightly viscous liquid.  It is miscible with water, alcohols, and many organic compounds, and has the molecular formula C₂H₆O₂, CAS: 107-21-1. It has a specific gravity of 1.115 and a flash point of 110 °C.

Production

Mono Ethylene Glycol is produced by the oxidation of ethylene at a high temperature in the presence of a silver oxide catalyst.  The ethylene oxide is then hydrated to yield mono ethylene glycol with di and tri ethylene glycols as co-products.

Uses

Monoethylene glycol (MEG) is an important raw material for industrial applications. MEG is utilized in the manufacture of polyester (PET) resins, films, fibers, antifreezes, coolants, aircraft anti-icer and deicers and solvents.

It is also utilised as raw material for paper industry, polyester Resins, adhesives and inks, chemical Intermediates, Heat Transfer, Fluids.

It is also a used as a dehydration agent in natural gas pipelines where it inhibits the formation of natural gas clathrates.

Tri Ethylene Glycol

CAS: 112-27-6

Tri ethylene glycol also known as TEG, triglycol and trigen is a colourless, viscous, non-volatile liquid with the molecular formula C₆H₁₄O₄, CAS: 112-27-6. It has a specific gravity of 1.125 and a flash point of 168 °C. It is well known for its hygroscopic quality and its ability to dehumidify fluids.

Production

Tri ethylene glycol is prepared commercially as a co-product of the oxidation of ethylene at high temperature, in the presence of a silver oxide catalyst.  The ethylene oxide is then hydrated to yield mono, di, tri, and tetra ethylene glycols.

Uses

The main uses for tri ethylene glycol are based upon its hygroscopic ability.  It is used as a dehydrating agent for natural gas pipelines where it removes the water from the gas before being condensed and reused in the system.  It is also a dehumidifying agent in air-conditioning units. It is also used to make chemical intermediates such as plasticisers and polyester resins.  It is an additive in hydraulic fluids and brake fluids, and TEG is also used as a solvent in many applications, including as a selective solvent for aromatics, and a solvent in textile dyeing.

Di Propylene Glycol

CAS: 25265-71-8

Di Propylene Glycol also known as oyybispropanol, 2,2-dihydroxyisopropylether, 1,1-oxydipropane-2-ol, di-1,2-propylene glycol, and DPG is a clear, colourless, viscous liquid with a characteristic odour and the molecular formula C₆H₁₄O₃, CAS: 25265-71-8. It is fully miscible in water and is also miscible with many organic solvents.  It has a flash point of 124 °C and a specific gravity of 1.023.

Production

Di propylene glycol is produced as a byproduct of propylene glycol production which occurs in a propylene oxide hydrolysis process.  Tri propylene glycol is another by-product of this process.

Uses

Di propylene glycol finds use as a chemical intermediate across a range of industries.  It is used as a component in the production of high volume plasticiser. It is also an initiator in urethane polyols, and a reactant in unsaturated polyurethane resins where it adds flexibility and hydrolytic stability.  It is also used for cutting oils, in hydraulic brake fluid production, and is a solvent for agricultural chemicals such as insecticides.  It is also used as a solvent for printing inks, nitrocellulose, cellulose acetate, lacquers and coatings.  It is an ingredient in industrial soaps and also has a role in the refining industry where it is used as an extraction solvent to extract aromatics.

Monopropylene Glycol

CAS: 57-55-6

Mono propylene glycol also known as propylene glycol, PG, propan1, 2diol, MPG is a clear, colourless, and viscous liquid with a characteristic odour and the molecular formula C3H8O2, CAS: 57-55-6. It is soluble in water, and has hygroscopic properties.

Mono Propylene Glycol Chemical Structure Composition.

Production

Mono propylene glycol is produced from propylene oxide. The most common process is by the non-catalytic hydrolysis of propylene oxide in a high-temperature and high-pressure environment. The second method is the catalytic one, which can proceed at 150 °C, in the presence of ion exchange resin, or a small amount of sulphuric acid or alkali. It can also be produced from glycerol which is a bio-diesel by-product.
The demand for, and consumption of, mono propylene glycol is high with an estimated 1.2 million tonnes produced yearly by plants situated around the world.
It has a flash point of 103 °C and a specific gravity of 1.04.

Uses

Mono propylene glycol is utilized across many different industries and some chemical manufacturers produce two grades of MPG to meet these varied needs.
The first grade is used in the food, cosmetics, and pharmaceutical industries. MPG is used as a solvent for food colourings and flavourings. In the personal care industry it is used as a moisturiser in make-up, shampoo, bubble bath and baby wipes, to name but a few examples. The pharmaceutical industry uses MPG as a solvent in oral, injectable, and topical formulations.
The main application for industrial grade MPG is as an antifreeze and aircraft wing and runway de-icer because the freezing point of MPG lowers upon mixing with water. It is also used in heat transfer liquids such as engine coolants.
It can also be used as a chemical intermediate in the production of high performance unsaturated polyester resins used in paints and varnishes. It is also an excellent solvent that is utilised in printing inks and it is also used in the manufacture of detergents which are used in the petroleum, sugar-refining, and paper making industries.
