Abstract
The present invention provides a method for minimizing the decomposition of cyanohydrins in exothermic chemical reactions involving cyanohydrins. The method comprises providing a reaction medium and reactants to a tubular reactor having internal mixing means, mixing the reaction medium and reactants to form a homogenous reaction mixture, removing heat from the reaction process and reacting the reactants to produce a mixed product having a bulk temperature. The method may further comprise cooling the reaction medium to a temperature from 1-10° C. cooler than the bulk temperature of the mixed product prior to providing the reaction medium to the tubular reactor.
