Truth about synthetic production of benzene and toluene by cracking of petroleum oils. Oil, Paint and Drug Rep., vol. 91, May 7, 1917, p. 48-H. Claims that the Rittman process is a failure, and explains the difficulties. (See also Gas Age, vol. 40, July 2,1917, pp. 13-14.) 826. Corr, J. W. Mineral oils. Reports of Progress of Applied Chemistry, vol. 1, 1916 (London, 1917), pp. 61-66. Summary of recent work, particularly that of Rittman, in cracking mineral oils. 827. Cross, Roy. The cracking of petroleum in the liquid phase. Met. and Chem. Eng., vol. 16, June 1, 1917, pp. 643-645. Paper read before the American Chemical Society, Kansas City. Gives conditions necessary for cracking petroleum in the liquid phase, compares this process with cracking in the gas phase, and gives results of experiments. Advantages gained are higher quality and yield, freedom from further cracking in the vapor phase, saving of heat, removal of gasoline as formed, and the deposit of carbon in the oil rather than on the walls of the tubes. 828. Cushman, A. S. Chemistry and American industry. Jour. Franklin Inst., vol. 183, May, 1917, pp. 557-574. Considers the manufacture of fuels by cracking processes, and substitutes for gasoline. 829. Desmauets, M. La pyrogenation des hydrocarbures. (The cracking of hydrocarbons.) Rev. Gen. Sci., t. 28, February, 1917, pp. 109-118. Reviews history of cracking processes, and describes the most noteworthy example. 830. Egloff, Gustav. Benzene, toluene, and xylene from petroleum. Met. and Chem. Eng., vol. 16, May 1.1917, pp. 492-495. Address before American Chemical Society, April, 1917. A general review of the work done ...
