Synthesis and Characterization of Hard Hydrolytic Borate Ester Surfactant

Abstract:

Boric acid and glycerol were adopted as the starting materials to react with cation exchange resin (CER) as the catalyst. The conversion of the products was characterized by acid value, titrated by potassium hydroxide (KOH) ethanol solution. It showed that the yield of the optimum products got to about 89%. Then they were modified with EO, gaining more than four carbon chains, and hydrolytic time was prolonged to 48 h. The structures of the unmodified and modified products were further confirmed by IR. The results indicated that hard hydrolytic borate ester surfactants with C-O-C bond were synthesized.
