摘要： Disclosed is a method of increasing the percentage of certain isomers made when di or tri-substituted benzenes are chlorinated in the presence of a Friedel-Crafts catalyst. The use of about 0.001 to about 1 wt % a cocatalyst during chlorination alters the isomeric ratio of the product mixture. In particular, the percentage of the 2,5-isomer is increased when said substituted benzene is ortho or meta-substituted, the percentage of the 3,4-isomer is increased when said substituted benzene is para-substituted, and the percentage of the 2,4,5-isomer is increased when said substituted benzene is 2,4-disubstituted, 3,4-disubstituted, or 2,5-disubstituted.

摘要： Disclosed is a method of making high purity 2,4- and 3,4-dichlorotoluene from parachlorotoluene that contains some metachlorotoluene. About 0.0001 to about 5 wt % of a Friedel-Crafts catalyst and about 0.5 to about 10 equivalents of a brominating agent are added to the parachlorotoluene. The metachlorotoluene is brominated, but most of the parachlorotoluene is not brominated. Without separating the brominated products from the unbrominated products, about 0.5 to about 1.5 equivalents of a chlorinating agent are added, whereby only the unbrominated products (i.e., the parachlorotoluene) are chlorinated. The resulting 2,4-dichlorotoluene and 3,4-dichlorotoluene can be separated by distillation.

摘要： Disclosed is an improved process for reacting a halogenated ester with an alkali metal alkoxide to form an alkoxy ester and a salt. A solvent is added to the halogenated ester prior to the addition of the alkali metal alkoxide. This results in a substantial increase in the particle size of the salt which greatly facilitates its separation from the solution of the alkoxy ester product.

摘要： The present invention provides an efficient process for the production of ethylene or a mixture of ethylene and vinyl chloride, in which some 1,2-dichloroethane (EDC) may also be produced, by reacting chlorine with ethane. The process is characterized by a conversion of ethane per pass through the reactor of at least about 50%, and a combined molar yield of ethylene and vinyl chloride of at least about 80% based on the ethane consumed. In accordance with this invention, there is provided a process for preparing ethylene or a mixture of ethylene and vinyl chloride by the reaction of ethane and chlorine which comprises: (a) providing a stream of ethane feed gas and a stream of chlorine feed gas; (b) preheating either said ethane stream only or both said ethane and chlorine streams; (c) thoroughly mixing said ethane and chlorine feed gases within about one second and at a molar ratio of ethane to chlorine of at least about 0.9:1.0; (d) said preheating being sufficient to enable the resultant mixture to have a temperature above the free radical formation temperature for chlorine; and (e) permitting said ethane and chlorine in said mixture to react so that the reacted mixture has a temperature between about 600.degree. C. and 800.degree. C.; whereby the combined molar yield of ethylene and vinyl chloride is at least about 80 percent of the ethane reacted.
