摘　　要：介绍了引发剂正丁基锂质量改进及其在热塑性弹性体SBS工业生产应用的情况。结果表明,通过生产设备与工艺的改进,正丁基锂质量指标如总锂含量、活性、氯丁烷含量、外观色泽和共价氯含量都达到美国FMC公司同类产品的标准,分别为总理质量分数(20.25±0.2)%、活性≥97.0%、外观为无色或微黄色无悬浮物透明溶液和w(共价氯)≤0.1%。工业应用试验结果表明,改进的引发剂正丁基锂产品质量与美国FMC公司的相当,完全能够取代进口产品应用于热塑性弹性体SBS的工业生产中。Quality improvement of n-butyllithium (n-BuLi) as initiator and its industrial application in producing of thermoplastic elastomer (TPE) were discussed in this article.By optimizing equipment and methodology,The quality of n-BuLi was the same as FMC's in US:concentration 20.25% ±0.2%(wt),activity≥97%,covalent chloride ≤0.1% (wt) and the appearance of solution was clear,colorless or yellow and no suspend.The results of industrial application showed that it could replace the imported product in production of thermoplastic elastomer SBS.
