Quaternary ammonium compounds polyurethanes

Long-chain alkyl chlorides can be used lor the synthesis of various amines, while benzyl chloride is used for production of quaternary ammonium compounds. Alkyl chlorides are used for the formation of organometallics, including the Grignard reagents as well as for alkylation of aromatics. One of the important reactions or phosgene is with diamines for production of diisocyunates (polyurethanes). 

Use Preparation of epoxy curing agents, polyurethane formation, corrosion inhibitor, textile finishing agents, intermediate for quaternary ammonium compounds. 

Use Catalyst for polyurethane foams, oxidation and polymerization catalyst, chemical intermediate (metal complexes, quaternary ammonium compounds, etc.), bromine and iodine addition compounds.

Cationic, anionic, and amphoteric surfactants derive thek water solubiUty from thek ionic charge, whereas the nonionic hydrophile derives its water solubihty from highly polar terminal hydroxyl groups. Cationic surfactants perform well in polar substrates like styrenics and polyurethane. Examples of cationic surfactants ate quaternary ammonium chlorides, quaternary ammonium methosulfates, and quaternary ammonium nitrates (see QuARTERNARY AMMONIUM compounds). Anionic surfactants work well in PVC and styrenics. Examples of anionic surfactants ate fatty phosphate esters and alkyl sulfonates.
