Abstract
Provided is a method for producing a 2-cyanoethyl group-containing organic compound having a high ratio of replacement by cyanoethyl groups and a high dielectric constant. More specifically, provided is a method for producing a 2-cyanoethyl group-containing organic compound comprising a step of reacting acrylonitrile with a hydroxyl group-containing organic compound in the presence of a quaternary ammonium salt as a catalyst through a Michael addition.
Claims3
A method for producing a 2-cyanoethyl group-containing organic compound comprising a step of reacting acrylonitrile with a hydroxyl group-containing organic compound in the presence of a quaternary ammonium salt as a catalyst through a Michael addition, wherein:
- the hydroxyl group-containing organic compound is selected from the group consisting of starch, pullulan, alkylcelluloses, hydroxylalkylcelluloses, hydroxylalkylalkylcelluloses and polyvinyl alcohols;
- the quaternary ammonium salt is selected from the group consisting of benzyltriethylammonium chloride, benzyltrimethylammonium chloride, benzyltrimethylammonium hydroxide, benzyltriethylammonium hydroxide and any combination thereof;
- and
- the quaternary ammonium salt is added in an amount of from 0.5 to 50 parts by weight relative to 100 parts by weight of the hydroxyl group-containing organic compound.
