Latest Patents
Honma's latest patents include a method for the preparation of an N-vinyl compound. This innovative method allows for the efficient production of compounds such as N-vinyl-2-pyrrolidone and N-vinyl-N-ethyl acetamide through the thermal decomposition of an N-(α-acyloxyethyl) compound. This compound is synthesized via an addition reaction between an NH group-containing compound, like 2-pyrrolidone, and a vinyl carboxylate, such as vinyl acetate, in the presence of an alkali. The process enables the in situ formation of the desired N-vinyl compound, which can be isolated with a very high overall yield.
Another significant patent involves the N-(α-acyloxyethyl) compound, which can be converted into an important N-vinyl compound through a thermal decomposition reaction under relatively mild conditions. This compound can be synthesized in high yield by the addition reaction of an NH group-containing compound with a vinyl carboxylate, facilitated by an alkaline compound.
