The silent electric discharge in petroleum gas with all glass discharge tube of 0.3cm discharge gap and alternating current of 60=, 15KV was carried out and the composition of the gasphase and liquid product was studied. Hydrocarbons higher than C_3 disappears almost completely after discharge of 3 hours and the contents of hydrogen and methane increase strongly in gas phase. The existence of hydrocarbons higher than C_< : 20> in the liquid product can be expected from its mean molecular weight, which varied with discharge time from 230 to 190. The iodine value of liquid products changes from 2,01 to 1,3 during the discharge and when compared with mean molecular weight, it appears that the liquid compound contains more than one double bonds as mean. The extraordinary high molecular weight and highly unsaturate character of liquid product suggest the importance of reactions at the innear wall of discharge tube. Through the period of discharge, the concentration of all gaseous components shows a straight line relation suggesting the presence of close connection among their reaction velocities.
