Purpose of work-is to study some kinetic laws of the heating decomposition reaction of monochloromethane in an airless environment at a slightly higher temperature. The growing demand for unsaturated ethylene series hydrocarbons in recent years shows how important the work in this field is. Pyrolysis of methyl chloride was carried out in a special flow and differential reactor. YuKS-20/30, YuKS-20, YuKS-30 and silicoaluminummagnesium phosphates: YuKS-30 Si , YuKS-30 Fe , YuKS-30, and YuKS- 30 modified with Mg were used as catalysts. The selectivity and acidic properties of modified YuKS-30, YuKS-20/YukS-30, YuKS-20 catalysts were studied using the thermoprogrammed desorption method of ammonia. Changes in CH3Cl conversion dynamics were observed at different temperatures and catalysts. From the obtained results, the selectivity for propylene in YuKS-20/YukS-30 and YuKS-20 samples was 32mol% and 35mol%, and in YuKS-30 it was 44mol%. In YuKS-20 and YuKS-20/YukS- 30 samples, the total selectivity of C 2 -C 3 formation at 500 min is 61 mol%, and in YuKS-30 it is equal to 71 mol%. Monochloromethane conversion was 80.5%. In the temperature range of 400-500℃, the activity of silicoaluminummagnesium phosphate was 77-84%, the active period of the catalyst increased at the volume rate of monochloromethane of 1000 h-1 . Ethylene extraction selectivity increases from 26 mol% to 41 mol% after 500 min at a volume rate of 1000-1500 h-1, and propylene selectivity increases to 45-47 mol%.
