以2－丙基庚醇和支链C0810醇（2－乙基己醇与2－丙基庚醇按等质量配制的混合物）为原料，分别与葡萄糖一步法合成支链烷基糖苷，测定了不同聚合度支链烷基糖苷的表面活性以及泡沫、乳化和润湿性能。结果表明，随着支链烷基糖苷平均聚合度的增加，临界胶束浓度cmc略有升高、最低表面张力γcmc逐渐降低、分子面积asm增大、吸附量Γmax减小；与单一的支链烷基糖苷相比，混合支链烷基糖苷体系具有更低的cmc、更大的表面吸附量和更小的分子面积；支链烷基糖苷的泡沫稳定性都没有直链烷基糖苷0810的好；随着平均聚合度的增加，支链烷基糖苷润湿力降低。

The branched chain glycosides were prepared from 2 -propyl -1 -heptanol and branched C0810 alcohol (which was mixed from equal mass 2 -propyl-1 -heptanol and 2 -ethylhexanol )separately with glucose by one step method,and their surface activities as well as the foaming,emulsifying and wetting performance were investigated. Results showed that cmc and asm of the branched chain glycosides increase with increase of average polymerization degree,butγcmc andΓmax decrease. The cmc and asm of mixed branched chain glycosides are lower than that of single branched chain glycoside,but the Γmax is bigger. The foam stability of the branched chain glycosides is worse as comparing with that of n - APG0810 . With increasing average polymerization degree,the wetting power of the branched chain glycosides decreases.
