摘 要:以自制的3-氯-2-羟丙基糖苷(CPG)与叔胺为原料,在正丙醇水溶液中合成了糖苷基季铵盐(CAPG)表面活性剂。优化工艺条件为:n(氯代糖苷)/n(叔胺)=1.4,m(正丙醇)/m(水)=0.5,反应时间4 h,在该条件下叔胺的转化率为88.4%。通过FTIR对产物的结构进行了分析,并对产物的表面活性、复配稳定性、泡沫性能及在硬水中的稳定性进行了测定。结果表明,其CMC为1.57×10-3mol/L,γCMC为27.3 mN/m;与十二烷基硫酸钠(K12)的混合溶液在n(CAPG)/n(K12)<0.6或n(CAPG)/n(K12)>1.0时,透光率均大于90%,具有很好的稳定性;在硬水中的平均稳定性、差示稳定性分别为5和5 5 5;在二次蒸馏水中初始泡沫体积为292 mL,在ρ(CaCO3)=300 mg/L硬水中的初始泡沫体积为255 mL。Glucoside quaternary(CAPG) was prepared with 3-chloro-2-hydroxypropylglucoside (CPG) and tertiary amine, using normal propyl alcohol aqueous solution as a solvent. The optimum conditions were shown as follows : n ( CPG )/n ( tertiary amine ) = 1.4, m ( normal propyl alcohol )/m (water) = 0. 5 ,the reaction time 4 h. The conversion rate of tertiary amine was 88.4%. The structure of product was characterized by FTIR. Surface activity, mixed compatibility, stability in hard water and foaminess were investigated. Results showed that CMC of the product is 1.57 × 10^-3 mol/L,γCMC is 27.3 mN/m, the transmittance of mixed system is over 90% when n( CAPG)/n(K12) 〈 0. 6 or n( CAPG)/n( K12 ) 〉 1.0 ,which represents a good compatibility;average stability and differential stability in hard water are 5 and ↑(-)5↑(-)5↑(-)5 respectively, the foaming volume exhibits power achieves 292 mL in distilled water and 255 mL in hard water of 300 mg/L(as CaCO3 ).
