Discussion on factors influencing use ratio of methanol in methane chloride production;

Methylcyclopentadiene was synthesized from cyclopentadiene,metallic sodium and methane chloride by a two-step method,which included synthesis of cyclopentadiene sodium by reaction of cyclopentadiene with metallic sodium and successive methylation of cyclopentadiene sodium with methane chloride.

The outlets of methane tetrachloride produced in the production facilities of chloromethane in China at present were proposed,such as conversion to diphenyl ketone,ethylene tetrachloride,cinnamic acid,trichloroacetyl chloride,methane chloride and chloroform.

Phase analysis of methyl chloride high pressure thermal chlorinating;

Experimental results were reported here regarding the gas phase conversion of CTC to methyl chloride by using transition metal salt composite catalyst embedded on active carbon.

Gas-liquid equilibrium data for water - triethylene glycol - methyl chloride ternary system were measured in an equilibrium cell at 0.

The optimum reaction conditions are as follows: reaction temperature 35 ℃, time 5 h, n(morpholine)∶n(monochloromethane)=1∶1.

Production processes of chlorinated methanes including monochloromethane, dichloromethane ,trichloromethane and carbon tetrachloride at home and abroad are introduced.

In this paper,the response factors of thermal conductivity detector(TCD) of monochloromethane and dimethyl ether are estimated and calculated by using group cross section area method,molecular diameter method and homologue linear rule method.
