Abstract
Experimental evaluation of various methods for the synthesis of purified N-cyclohexylmaleimide was carried out. It was shown that the monomer obtained by the combined purification scheme, including steam distillation and sequential recrystallization in organic solvents of diff erent polarities, allows to obtain N-cyclohexylmaleimide with the content of the main substance of at least 99.5 wt.% and with a yield of 70–80 wt.%.
The monomer synthesized according to the proposed scheme does not contain polymerization-active and coloring impurities. It makes it possible to obtain unpainted methacrylic copolymers on its base with high heat resistance.
