Abstract
A method for producing an amine. The first step is contacting a cyanide, an acid, water and a substrate compound capable of generating a carbonium ion by reaction with the acid to generate a first reaction intermediate. The second step is contacting the first reaction intermediate with water to form a second reaction intermediate. The third step is removing cyanide present in the second reaction intermediate to a concentration less than 10 ppm. The fourth step is contacting the second reaction intermediate with an alkali metal hydroxide to form the amine.
