摘要
以葡萄糖、月桂醇为原料，利用直接法合成了十二烷基葡糖苷，采用正交实验法，优选出反应最佳工艺条件：反应温度，１１５℃；反应压力，２．６７ｋＰａ；反应时间，４．０ｈ；催化剂与葡萄糖质量比０．００７∶１；月桂醇与葡萄糖物质的量比５∶１，得率１５８．７％。并测定了产品的表面张力和起泡性质。
Dodecyi polyglucoside was synthesized by the direct reaction of glucose with laurel alcohol. Orthogonalizing design was adopted. The optimum technological condition was obtained:reaction temperature,115℃;reaction pressure,2.67kPa;reaction time,4.0h;mass ratio of catalyst and glucose,0.007∶1;mole ratio of laurel alcohol and glucose,5∶1; the yield reached 158.7%. The properties of surface tension and foaminess were measured.
