FIELD: chemistry.
SUBSTANCE: invention relates to a method for synthesis if 3-(methylthio)propanal and 2-hydroxy-4-(methylthio)butane nitrile through a catalytic reaction for respectively bonding methylmercaptan to acrolein and hydrocyanic acid to 3-(methylthio)propanal. In the said methods, the catalyst is heterogeneous, does not dissolve in the reaction medium and has formula (I) 
in which R1 and R2 represent hydrogen, alkyl with chain length from C1 to C12, and R1 can assume values different from R2, x is a number ranging from 0 to 6 and A represents a synthetic resin.
EFFECT: reduced material and technical expenses on production.
