Abstract
ABSTRACT Novel reducing emulsifier monomers 2-(dimethylamino)ethyl dodecyl maleate (DMAEDM) and 2-(dimethylamino)ethyl dodecyl itaconate (DMAEDI) containing polymerisable double bonds, tertiary amine and long-chain aliphatic hydrocarbons were creatively designed and synthesised. Reducing emulsifier monomers (REM) were prepared using dodecanol, acid anhydride and 2-dimethylaminoethyl chloride hydrochloride through a two-step reaction process. The optimum reaction temperature and ratio of chemicals were determined to achieve higher yield and purity of REM products. The product purity was above 95% as determined by gas chromatography. The structure of the products was confirmed by infrared spectroscopy (IR) and proton nuclear magnetic resonance (1H-NMR) spectroscopy. The novel reducing emulsifier monomers have been determined to have good emulsifying performance.
