TriPropylene Glycol (TPG) Cas 24800-44-0 Tripropylene Glycol or TPG is mixture of isomers present as a clear liquid, odorless and with a medium viscosity. It’s naturally hygroscopic (it attracts water from atmosphere). It is completely soluble in water and miscible with many organic solvents. The molecular formula is C9H20O4. Tripropylene Glycol Chemical Structure Composition. Production […]

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 […]
