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 […]

Polyethylene Glycol (PEG)
Polyethylene Glycol (PEG) is a clear, colorless, viscous liquid soluble in water.
Liquid PEG are soluble in acetone, alcohols, benzene, glycerin, and glycols.
Solid PEG are soluble in acetone, dichloromethane, ethanol (95%), and methanol; they are slightly soluble in aliphatic hydrocarbons and ether but insoluble in fats, fixed oils, and mineral oil.
Polyethylene Glycol Chemical Structure Composition.
Production
Polyethylene glycol (PEG) is formed by the reaction of ethylene oxide and water under pressure in the presence of a catalyst.
Uses
