A PROCESS FOR THE PREPARATION OF OLEFINIC MERCAPTANS WHICH COMPRISES REACTING AN OLEFIN-CONTAINING COMPOUND WITH AN EXCESS OF HYDROGEN SULFIDE AT AN ELEVATED TEMPERATURE WITHIN THE RANGE OF BETWEEN 100 AND 325*F. WHILE MAINTAINING A CONSTANT ELEVATED PRESSURE WITHIN THE RANGE OF 400 TO 800 P.S.I.G. SUCH THAT EXCESS HYDROGEN SULFIDE WILL BE PRESENT AS A LIQUID IN THE REACTING MASS SUCH THAT IT WILL ABSORB THE HEAT OF REACTION AND THEREBY VAPORIZE IN A QUANTITY SUFFICIENT TO MAINTAIN SAID TEMPERATURE.
