2837. RUBIN, L. C. (M. W. Kellogg Co.). Synthesis of Organic Compounds. United States Patent 2,448,279, Aug. 31, 1948; appl. filed Aug. 23, 1944, Serial No. 550,799; 3 claims (Cl. 260-449.6). Chem. Abs., vol. 42, 1948, p. 9123.

Powdered catalyst such as one of the composition Co: 0.15 MgO: 2.0 Superfiltrol was used in a reactor sufficiently large to allow 2 distinct phases, the one having a density ordinarily not less than ½ that of the settled mass and the other a diffuse phase large enough to allow disengagement of catalyst by settling. After the catalyst was raised to reaction temperature, the preheated feed gas was introduced. Conversion started and the operation continued for some time, with the temperature controlled by H₂O bath in jacket. The H₂O was withdrawn from the jacket, and the temperature controlled by vaporization of a light naphtha introduced into the reaction zone through nozzles. The naphtha b. 126° -360° F. had been produced in the process. An example using H₂O as the injected coolant and 1 using the injection method in combination with indirect heat exchange are given. Conditions and results are given in tabular form. 6 United States patents and 2 foreign patents cited.
