核磁共振法研究表面活性剂L-113A的HLB值

^1HNMR Studies of Surfactant L-113A HLB Value

采用核磁共振法研究表面活性剂L-113A的亲水亲油平衡值HLB,分析出聚异丁烯基团中H质子的个数,通过H质子的个数得出聚异丁烯结构中异丁烯的个数为20,计算出聚异丁烯结构的分子量为1 401,L-113A的分子量为1 671,从而得到L-113A的HLB值为3.38.

The HLB value of surfactant L-113A has been measured by ^1HNMR. The number of H is analyzed . The isobutylene number in the polyisobutylene is 20 by calculation of H number, so that the polyisobutylene structure molecular weight is 1 401. The total molecular weight of L-113A is 1 671. The HLB value of surfaetant L-113A is determined as 3.38.
