Preparation of biphenyl from the crude benzene fraction of pyrolysis products. II. Ismailov, R. G.; Aliev, D. A.; Ivanova, T. M. Azarbaycan Neft Tasarrufati (1963), 42(5), 33-5. CODEN: AZNKAY ISSN: 0365-8554. Journal written in Russian. CAN 64:26521 AN 1966:26521 CAPLUS Abstract cf. CA 60, 5253h. The possibility of the use of the crude benzene fraction for the prepn. of Ph2 and pure C6H6 was investigated. The thermal condensation of this fraction at 850 yields 5.8-9.3% gas, 4.3-9.1% coke, and 79.1-82.8% tar. The components of the gas are H 58.8-76.4, CH4 17.4-30.8, C2H6 1.6-2.9, and C2H4 4.1-7.8%. Steam distn. of the tar fraction yields 53.8-57.3% C6H6 and 12.2-16.1% Ph2. The process comprises pyrolysis and cyclization of the olefins, partial decompn. of C6H6, and condensation of C6H6 to Ph2. The Ph2 obtained by recrystn. has a purity of 98.8-9.0% and a m.p. of 66.6-8.8. A high-quality, pure C6H6 contg. 98.8-9% aromatic compds. can also be obtained by this process without H2SO4 purification.
