磺基琥珀酸酯铵的合成及其抗静电性能评价

Synthesis and anti-static performance evaluation of ammonium sulfosuccinate

以马来酸酐、脂肪醇和亚硫酸氢钠为原料经过酯化、磺化反应合成磺基琥珀酸酯钠,然后分别与四丁基氯化铵(TBAC)、十六烷基三甲基氯化铵(CTAC)和十四烷基二甲基苄基氯化铵反应,合成了12个不同结构的磺基琥珀酸酯铵(ASS)油溶性离子液体,研究了磺基琥珀酸酯铵中阴、阳离子的烃基结构对磺基琥珀酸酯铵抗静电性能的影响。结果表明,阳离子的烃基结构对磺基琥珀酸酯铵抗静电性能的影响较大,阳离子为四丁基铵和十六烷基三甲基铵的磺基琥珀酸酯铵,在0号商品柴油中加剂量为50 mg/L时,柴油电导率增加值(Δκ)可达到100 pS/m,符合行业标准要求。

Sodium sulfosuccinates were synthesized through esterification and sulfonation reaction frommaleic anhydride, aliphatic alcohol and sodium hydrosulfite. Twelve ammonium sulfosuccinates （ASS） ionic liquid with different structures were synthesized by sodium sulfosuccinate reacting with tetrabutylarnmonium chloride （TBAC） , hexadecyltrimethylammonium chloride （CTAC） and benzyldimethyltetradecylammonium chloride respectively. The anti-static performance of the ASS was evaluated and the effects of the alkyl group structure of anions and cations, additive dose on the anti-static performance of the ASS were discussed. The result showed that the alkyl group structure of cations had great influence on the anti-static performance of the ASS. The dosage of 50 mg/L in the No. 0 diesel fuel in commodity, the conductivity increasing value（△κ） can reach 100 pS/m when the cations of the ASS were tetrabutyl ammonium and hexadecyl trimethyl ammonium. It can meet the industrial standard＇ s requirement.
