To identify the impact of technological process parameters on the yield of methyl acetylenic fraction in the reaction of elimination of DCP in the presence of zeolite CaX, studies have been carried out and changes in temperature and contact time revealed. It became evident that the best performance out of A and MA was obtained at temperature of 400º C and contact time of 7.4 sekond. Further rise in temperature, as well as contact time leads to the increase in the formation of hydrogen chloride and unsaturated hydrocarbons.
