研究了甲基羧乙基二聚氧乙烯基硅烷(I)的合成方法和乳化性能。甲基二氯硅烷(II)和丙烯酸(III)发生硅氢加成反应后,不经分离,直接以聚氧乙烯600醇解反应得到I,其化学结构经红外光谱分析表征。考察了原料配比、温度和时间对硅氢加成反应转化率的影响。在优化工艺条件下:n(II):n(III) = 1:1.2,0.002 g/mL氯铂酸异丙醇溶液0.125 mL,60 mL THF,0.02 mol II在55℃反应20 h,硅氢加成反应转化率达到75.3%。0.1% I水溶液的表面张力为37.0 mN/m,I用于45%石蜡乳液的制备,可有效提高乳液的分散性和离心稳定性。
Synthesis and performance of methyl carboxyethyl dipolyoxyetheylene silicane (I) were investi-gated. Methyl carboxyethyl dipolyoxyetheylene silicane (I) was synthesized by addition of Si-H from methyldichlorosilae(II) and acrylic acid(III), and then by alcoholysis with polyoxy-ethylene- 600. The final product I was characterized by means of FT-IR. The effects of ratio of II and III, temperature and time on the conversion of Si-H addition were investigated respectively. In the optimal process conditions: n(II):n(III) = 1:1. 2, 0.125 mL 0.002 g/L H2PtCl6/i-PrOH solution, 0.02 mol II reacted at 55?C for 20 h, and the conversion of Si-H addition was 75.3%. The surface tension of 0.1% aqueous solution of I is 37.0 mN/m. I was used in preparation of 45% paraffin emulsion and promoted effectively its dispersivity and centrifugal stability.
