摘　要：以氨基酸酯盐酸盐、聚异丁烯丁二酸酐（PIBSA）为主要原料，N，N′-二环己基碳二亚胺（DCC）为催化剂，基础油为溶剂，经反应合成了聚异丁烯丁二酸酐衍生物类乳化炸药用乳化剂。考察了氨基酸酯盐酸盐种类、基础油种类、反应物配比、反应温度及反应时间等因素对乳化剂性能的影响。优化反应条件为：以220 N基础油为溶剂，n（PIBSA）∶n（o-叔丁基-L-丝氨酸甲酯盐酸盐）=1.0∶1.1，反应温度140℃，反应时间6 h。此合成工艺简单，安全可靠，适合工业化生产。所合成乳化剂临界乳化剂用量为1 g，乳胶基质水溶值为1.26%，适合用于制备乳化炸药。

Abstract：Emulsifier for emulsion explosives of polyisobutylene dihydride derivatives was synthesized from amino-acid ester hydrochloride and polyisobutylene succinic anhydride (PIBSA) using N,N'-dicyclohexylcarbodiimide (DCC) as catalyst in base oil. The effects of amino-acid ester hydrochloride type, base oil type, molar ratio of reactants, reaction temperature and reaction time on the properties of emulsifier were investigated. The optimal reaction conditions include n(PIBSA) ∶n(O-tert-butyl-L-serine methyl ester hydrochloride) of 1.0∶1.1, reaction temperature of 140℃ and reaction time of 6 h. This synthetic process was simple, safe and reliable, suitable for industrial production. The critical emulsifier dosage of the title emulsifier was 1 g and the water solubility value of the emulsion was 1.26%, which is suitable for the preparation of emulsion explosive.
