摘要： In a process for obtaining substantially sulfur free pure naphthalene from bituminous coal tar and thionaphthene as a by-product, a de-phenolized thionaphthene-containing naphthalene fraction from oxidative purification is extracted with concentrated sulfuric acid and acetic acid anhydride in benzene. The thionaphthene is converted into its sulfonic acid derivative and water washed from the benzene-naphthalene mixture. The benzene is distilled leaving pure naphthalene. The sulfonic acid group is cleaved from the thionaphthene with superheated steam to yield thionaphthene.

摘要： Isobutylene containing a minor amount, e.g. 0.06-0.10 wt %, of n-butene-1 is subjected to gas phase isomerization using hydrogen and Group VIII metal catalyst to convert the butene-1 to butene-2 with at least 65% conversion and no more than 0.3% hydrogenation of the isobutylene; butene-2 is more readily separated from the isobutylene by distillation. Isomerization conditions applied are defined by a pressure of 3 to 5 bars gauge, a temperature of from 40.degree. to 50.degree. C., a space velocity of from 150 to 300 vol/vol/hour, a mass velocity of from 1.1 to 1.5 metric tons/m2/hour and a hydrogen/feed volume ratio of not more than 2.5%.

摘要： A hydrocarbon stream comprising C.sub.2 to C.sub.8 hydrocarbons is stripped at a high temperature to allow passage of the stripper bottoms stream into a reaction zone without further heating, and the effluent of the reaction zone is then heat exchanged against the feed stream to the stripper column to recover heat. Operation of the reaction zone at the desired temperature is achieved by adjusting the amount of the stripper bottoms stream which is split off for cooling by heat exchange against the feed to the stripper column. The cooled split-off portion is then admixed with the remaining high temperature portion. Adjusting the flow rate of the portion of hot reaction zone effluent which is heat exchanged against the stripper feed stream is performed to control either the temperature of the stripper feed stream or the temperature of the reaction zone effluent as it is passed to a downstream operation.
