Toluene Diisocyanate (TDI) CAS:584-84-9 TDI (Toluene Diisocyanate) is produced by a 3 step reaction. The first step is the nitration of toluene to obtain dinitrotoluene. Second step is the catalytic hydrogenation of Dinitrotoluene into toluene diamine TDA. Finally, the TDA react with phosgene to produce the TDI. TDI is commonly sold under 3 different ratio […]

Di Ethylene Glycol
Di Ethelene Glycol (also known as DEG, 2,2-oxydiethanol and glycol ether ether diglycol) is a clear, colourless, odourless liquid with the molecular formula C4H10O3, CAS: 111-46-6. It has a specific gravity of 1.118 and a flash point of 154 °C.
It is soluble both in water and in many organic compounds and has hygroscopic properties which makes it a useful industrial chemical.
Di Ethelene Glycol Chemical Structure Composition.
Demand of diethylene glycol is based on the demand for monoethylene glycol. The process consists of the oxidation of ethylene at a high temperature in the presence of a silver oxide catalyst. The ethylene oxide is then hydrated to yield diethylene glycol with monoethylene glycol and triethylene glycol as co-products.
Di ethylene glycol is utilized in the industry of paper, tobacco, glue, cellophane and natural gas industry due of its hygroscopic properties.
Di ethylene glycol is also used as a chemical intermediate in the manufacture of unsaturated polyester resins, plasticisers, acrylate and methacrylate resins, and urethanes. It can also be used as a cement grinding aid, in solvent extraction, and in printing ink.
Di ethylene glycol is now being displaced by tri ethylene glycol as the lower toxicity of tri ethylene glycol.
