摘要
以ＦＡＢＭＳ、ＥＩＭＳ、ＦＴＩＲ等手段鉴定了从工业产品中分离得到的一种未知表面活性剂的化学结构为聚氧丙烯／聚氧乙烯共聚物，其商品名称为普鲁洛尼克（Ｐｌｕｒｏｎｉｃ）型非离子表面活性剂．用ＦＡＢＭＳ谱观察到该表面活性剂同系物的各种准分子离子峰呈近似的高斯分布，根据各种准分子离子峰的相对强度得出该表面活性剂同系物的分子量分布及平均分子量．
from the informations of FABMS, EIMS and FTIR spectra, one kind of non ionic surfactants has been identified as the pluronic tyle non ionic Surfactant, or polyoxypropylene/polyoxyethylene copolymer.the molecular weight distribution of homologue of the pluronic type non ionic surfactant have also been determined by FABMS.
