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. |
Key words:polyisobutenyl succinic anydride; O-tert-butyl-L-serine methyl ester hydrochloride; emulsifier; synthesis process |
