Abstract

275,563. Guggenheim, D., Guggenheim, M., Guggenheim, S. R., Guggenheim, S., Macgowan, J. K., and Smith, E. A. C., (trading as Guggenheim Bros), (Assignees of Fischer, A. H.). Aug. 3, 1926, [Convention date]. Void [Published under Sect. 91 of the Acts]. Xantho compounds.-Ethyl xanthic anhydride may be made by adding ethyl chloroformate to a mixture of potassium ethyl xanthate and ethyl alcohol and allowing to stand; on diluting with a large volume of cold water, the anhydride separates. Propyl and butyl xanthic anhydrides may be similarly prepared.
