Synthesis and Property of Polymerizable Sodium Sulfosuccinic Diester

Abstract:

Using different long-chain alcohols (octanol, dodecanol, tetradecyl alcohol), maleic anhydride, allyl chloride, sodium bisulfite as the main raw materials, a series of polymerizable emulsifier--allyl-type sodium sulfosuccinic diesters have been synthesized in this paper. Through single-esterification and double-esterification, three diesters have been synthesized. The sulfonation conditions are as follows: using sodium maleic acid monoester as the phase transfer catalyst, sodium bisulfite and double-ester were allowed to react in the ratio of 1.0: 1.1 at 110°C for 4h in the solvent of a mixture of ethanol and water. The yield of sulfonation on sodium octyl sulfosuccinic diester and sodium dodecyl sulfosuccinic diester as well as sodium tetradecyl sulfosuccinic diester were 94.8%(Ⅰ), 96.78%(Ⅱ) and 93.6%(Ⅲ), respectively. All products were charac 4 terized by IR spectra and 1H NMR, and their surface properties were tested. The results showed that the surface properties of dodecyl sodium maleic acid monoester and tetradecyl sodium maleic acid monoester as well as sodium tetradecyl sulfosuccinic diester were better than lauryl sodium sulfate, and they were all suitable for being used as emulsifier.
