In this article, 12-acryloyloxystearic acid was synthesized, which was then used to prepare the magnesium 12-ac-ryloyloxy stearate detergent. Reaction conditions for synthesizing 12-acryloyloxystearic acid, including the molar ratio of 12-hydroxystearic acid to acrylic acid, the catalyst amount, the esteriifcation temperature, and the esteriifcation time, were optimized. Under the optimized conditions, the 12-acryloyloxystearic acid with an acid value of 159 mgKOH/g and a melt-ing range of between 70.4℃and 71.4℃was obtained. The structure of 12-acryloyloxystearic acid was conifrmed by FT-IR spectroscopy. Results of preparing magnesium 12-acryloyloxy stearate detergent showed the existence of acryloyloxy radical in 12-hydroxystearic acid could improve the quality of lubricant detergent greatly.
