【Abstract】 Anionic reactive surfactants of sodium sulfosuccinic diesters were synthesized from maleic anhydride by monoesterification,O-alkylation and selective sulfonation.Thus,maleic anhydride reacted with fatty alcohols at 90 ℃ for 3 h to produce maleic monoesters.The monoesters then reacted with allyl chloride at 50 ℃ or isocrotyl chloride at 65 ℃ in the presence of sodium carbonate,Et₃N and acetone for 6 h to give the corresponding maleic diesters.Finally,the diesters reacted with sodium bisulfite at 120 ℃ for 3 h to produce sodium sulfosuccinic diesters.Structures of the products were confirmed by ¹HNMR and IR.更多还原
