    摘要: A process for the dehydrohalogenation of a (polyhaloalkyl)benzene containing a benzylic halogen such as 1,3-dichloro-5-(2,4,4,4-tetrachlorobutyl)benzene by contacting the (polyhaloalkyl)benzene with a suitably active Lewis acid catalyst such as SbCl.sub.5 or TiCl.sub.4 under conditions sufficient to catalyze said dehydrohalogenation to form a (polyhaloalkenyl)benzene such as 3,5-dichloro-.alpha.-(2,2,2-trichloroethyl)styrene.

    摘要: In an isomeric mixture of ar-substituted-1-(sec-alkyl)benzenes, such as a mixture of 2-chlorocumene, 3-chlorocumene and 4-chlorocumene, the alkyl groups of the 3-isomer and 4-isomer react preferentially with a halogen in the presence of a catalyst such as benzoyl peroxide to form a 3-halo-1-(.alpha.-alkyl, .alpha.-halo)alkylbenzene and 4-halo-1-(.alpha.-alkyl, .alpha.-halo)alkylbenzene such as 3-chloro-.alpha.-bromocumene, and 4-chloro-.alpha.-bromocumene.

    摘要: In a mixture of isomers of ar,ar-dihalo-ar-alkylbenzene wherein the halogen substituents are meta oriented with respect to each other, (e.g., a mixture of 3,5-dichlorocumene and 2,4-dichlorocumene), the 2,4-dihalo-1-alkylbenzene is preferentially reacted with an alkylating agent, e.g., an alkyl halide, by contacting the mixture with the agent in the presence of a Friedel-Crafts catalyst at a temperature of less than about 90.degree. C. The resulting alkylated isomer is readily separated from the unreacted isomer(s) by simple distillation.

    摘要: The herbicidal action of a herbicidal triazine upon weeds is enchanced upon also applying to the weeds a second herbicidal component, a butyl or pentyl glycol sulfonate or glycol sulfamate having 3, 5 or 3 substituted phenyl in the 2-position of the butyl or pentyl chain. The glycol sulfonate or sulfamate also adds its own herbicidal action to increase effectiveness.Both components are applied simultaneously as a novel composition which may also contain crop oil or crop oil concentrate. Application is made post-emergently before weeds reach about the 8 leaf stage. Advantageously, in an additional step, triazine alone or in combination with at least some of the sulfonate or sulfamate is also applied at planting or very early postemergently prior to the treatment described.
