Abstract
The present disclosure relates to a preparation method of an acrylic ester compound. The preparation method of an acrylic ester compound according to the present disclosure enables the use of acrylic anhydride as a reactant instead of acryloyl chloride, which is difficult to handle, by using an alkane diamine as a catalyst. Therefore, not only can the reaction be carried out at a low temperature, but also conversion to an acrylic ester compound and a yield of the acrylic ester compound can be improved.
