  • Synthesis of 3,5-dichloroalkylbenzene and recovery of 1,3-dichlorobenzene
    Patent number: 5030777
    Abstract: A process for synthesizing 3,5-dichloroalkylbenzene and recovering 1,3-dichlorobenzene from a starting mixture of 1,3- and 1,4-dichlorobenzenes. The process includes the sequential steps of selectively alkylating the 1,3-dichlorobenzene in the starting mixture; isomerizing a portion of the 2,4-dichloroalkylbenzene produced to 3,5-dichloroalkylbenzene; separating the 1,4-dichlorobenzene from the isomeric mixture of dichlorocumenes; and selectively transalkylating the dichlorocumenes to yield alkylbenzene, 3,5-dichloroalkylbenzene and 1,3-dichlorobenzene. By selectively alkylating only a portion of the 1,3-dichlorobenzene, the reaction products are obtained in good yield and substantially free of undesirable by-products.
