Abstract
A new kind of phosphate polyether modified trisiloxane (PTSS) was synthesized by the esterifi⁃cation reaction of hydroxyl- terminated polyether modified trisiloxanes (TPETS) with phosphoric acid (H3PO4). TPETS was prepared by hydrosilylation of 1,1,1,3,5,5,5- heptamethyltrisiloxane (HTSO) with al yl polyoxyethyl⁃ene ether (FAE- 10) using chloroplatinic acid as the catalyst. The esterification reaction conditions of PTSS syn⁃thesis were optimized using orthogonal experiment. The structure of PTSS was characterized by infrared spec⁃tra (IR). The properties of PTSS, such as critical surface tension (γcmc), critical micel e concentration (cmc), foam⁃ing properties and emulsifying ability were measured. The results showed that the optimum conditions of the esterification reaction for the PTSS: reaction temperature 80 ℃, reaction time 4 h, n(TPETS): n(H3PO4)=1:1.1. And the γcmc of PTSS solution was 21.9 mN/m, the cmc of PTSS solution was 5.0×10- 4 g/mL. The foaming pow⁃er of 0.1% PTSS (mass fraction) solution was 3.03 and foam stability after 5 min was 0.590. The emulsifying ability of 0.1%PTSS solution were 131 and 304 s for kerosene and benzene, respectively.关键词
