ABSTRACT OF THE DISCLOSURE Continuous process for producing carbon disulfide 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 1.0 to 12 atmospheres. A stream of sulfur at a temperature of at least 650°C and a stream of the hydrocarbon gas are fed into a reaction zone continuously. The flow conditions and mixing conditions of said gas and vapor streams are such that the hydrocarbon gas becomes substantially completely mixed with the sulphur vapor before the hydrocarbon comes into contact with a wall of the reaction zone. The improvement comprises moving the reaction mixture vertically from the zone of introduction of the hydrocarbon stream, the temperatures and rates of flow of the vapor and gas are such that the calculated mixing temperature thereof is in the range of about 585°to 700°C., preferably about 625° to 675°C.
