Abstract
A novel organic silicon surfactant, polyether modified disilane, was prepared via a two-step reaction. The hydrogen-containing disilane was first prepared by ( CH3 ) 3 SiCl and ( CH3 ) 2 HSiCl based on Wurtz coupling method using sodium as the reductive coupling agent and xyiene as the dissolvant, and the obtained product was characterized by IR, UV and GC. The optimum experiment conditions of the synthesis were as follows :n( (CH3)3SiCl):n( (CH3)2HSiCl) = 1. 2:1, the concentration of reactants with 1. 8 mol/L, 15-crown-5 dosage with 2% of the reaction materials, the reaction temperature and time were 80℃ and 11 h, respectively. The polyether modified disilane surfactant was then synthesized via hydrosilation of the obtained hydrogen-containing disilane and methoxy-terminated polyether polyols using Karstedt Pt as catalysts, the experiment conditions of the synthesis were as follows; the reaction temperature was 95℃ and the reaction time was 4 h. Experimental results showed that the critical micelle concentration ( CMC) was 0. 9 g/L and the surface tension was 22. 49 mN/m. The hydrolytic stability of product was good under pH = 6. 94 and pH = 4. 12 conditions.关键词
