Investigation of the thermal condensation of petroleum-derived benzene for the production of biphenyl.    Ismailov, R. G.; Aliev, D. A.; Ivanova, T. M. Azarbaycan Neft Tasarrufati  (1963),  42(4),  35-7.  CODEN: AZNKAY  ISSN: 0365-8554.  Journal  language unavailable. CAN 60:30034 AN 1964:30034 CAPLUS

Abstract

A study was made of the prepn. of biphenyl (I) (used as a heat-transfer agent and in the manuf. of elec. insulating fluids) by thermal condensation of petroleum-derived C6H6.  Pure C6H6 from the light oil fraction obtained by pyrolysis of liquid petroleum distillates was used as raw material, and the reaction was studied in a lab. app. consisting of a Cr-Ni reaction tube heated in an elec. furnace, condensers for liquid products, and a flask for measuring the vol. of gaseous products.  Liquid products were sepd. by steam-distn. into a C6H6 fraction and a I fraction.  I was purified by recrystn. from EtOH.  The reaction was investigated at temps. ranging from 600 to 850.  No condensation occurred at temps. of 600-700, and only small amts. of I and gaseous products were formed at 750.  At 800-50, condensation of C6H6 gave 88.4-91.5% resinous products, and 2.5-4.0% gaseous products, and 3.3-4.6% coke.  Gaseous products consisted of 89.3-90.6% H and 9.4-10.7% CH4.  The yield of I increased with temp. from 8.7 to 18.6%.  Decreasing the contact time to 0.33 sec. at 850 increased the yield of I to 19.6%.
