The kinetic regularities and mechanism of proceeding the reaction of esterification of dichloromaleic anhydride with ethyl alcohol in the presence of zeolite catalysts HZSM, ЦВК have been studied. It has been established that is possible to describe kinetics of the reaction by the low of homoeneus acidic catalysis. The supposed stage mechanisms of proceeding the reaction has been suggasted the kinetic model, depicting adequatly the received results has been made up. The parameters of  the kinetic model have been  calculated.
