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 […]

Neo Pentyl Glycol (NPG)
Neo Pentyl Glycol Chemical Structure Composition
Neo pentyl glycol (NPG) is produced with formaldehyde and isobutyraldehyde in an aldol reaction. The intermediate obtained is converted to NPG with catalytic hydrogenation of the aldehyde group to the neo pentyl glycol.
Neo pentyl glycol (NPG) is used in production of polyester resins for coatings, Gel coats (top coat of composite), coil coatings, synthetic lubricants, plasticizers, adhesives.
Improve the heat stability of polyester.
