摘要
介绍了聚氧乙烯酸类非离于表面活性剂的质谱,特别是电于轰击质谱(EI/MS)的裂分规律,并根据其一系列主要碎片质量和强度来判断其氧乙烯的聚合度及烷基链长.
In this paper, the EI/MS fragmentation of polyoxyethylene ethers nonionic surfactants were discussed.Based on a series of main mass fragmentation fragmentation peaks,the numbers of oxyethylene group and the length of alkyl chain couldbe determined.
