Abstract
Continuous process for producing carbon bisulfide by reaction of sulfur and hydrocarbon gas containing a multi-carbon hydrocarbon having at least three carbon atoms at a pressure in the range of 3.5 to 12 atmospheres. A stream of sulfur at a temperature of at least 650.degree. C and a stream of the hydrocarbon gas are fed into a reaction zone continuously. The temperatures and rates of flow of said vapor and gas are such that the calculated mixing temperature thereof is in the range of about 585 to 700.degree. C., and the flow conditions and mixing conditions of said gas and vapor streams are such that the hydrocarbon gas become substantially completely mixed with the sulfur vapor before the hydrocarbon comes into contact with a wall of the reaction zone.
