  • Production and Use of 3,4' and 4,4'-Dimethylbiphenyl Isomers
    Publication number: 20210053890
    Abstract: Processes are described for separating 3,4?- and 4,4?-dimethylbiphenyl from a mixture comprising at least 3,3?-, 3,4?- and 4,4?-dimethylbiphenyl. In the processes, the mixture is cooled to produce a crystallization product comprising at least of the 4,4?-dimethylbiphenyl from the feed mixture and a first mother liquor product. The first mother liquor product is distilled to produce a bottoms stream enriched in 4,4?-dimethylbiphenyl as compared with the first mother liquor product and an overhead stream deficient in 4,4?-dimethylbiphenyl as compared with the first mother liquor product. The overhead stream is then cooled to produce a second crystallization product comprising at least part of the 3,4?-dimethylbiphenyl from the overhead stream and a second mother liquor product.
