Reaction Conditions

Reaction Steps

Approximately 225 pounds of decylmercaptan are loaded into a jacketed reactor equipped with an agitator. 1.25 pounds of zinc chloride catalyst are added through the manhole. The system is heated to approximately 140° C. and 130 pounds of 2-ethyl-2-oxazoline are added at the rate of 3 lbs/min in about 45 minutes. About 30 minutes are allowed for the reaction to be completed, the reactor cooled to approximately 120° C. and 155 pounds of 32 weight percent hydrochloric acid are then added to the reaction mixture. The reactor is heated to 150°-160° C., at which time the vapor pressure of the system is approximately 60 psi. The temperature is maintained near 150° C. for 2 hours to complete the hydrolysis.
