Flow Chart:

At present, light stabilizers are produced in industry mainly by transesterification, which is obtained by transesterification of hydroxyethyl piperidinol with dimethyl succinate, but the price of dimethyl succinate is higher than that of succinic acid; In the direct esterification method, succinic acid is used as raw material instead of dimethyl succinate to react with hydroxyethyl piperidinol.
