    Abstract: Organic tertiary polyphosphine monoxides are prepd. in high yield. Organic tertiary polyphosphine compds. (I) [R1, R2, R3, R4, R5, R6, R7, R8=hydrocarbon (C1-30); Y=hydrocarbon containing only carbon and hydrogen, hydrocarbon containing oxygen, nitrogen or sulfur; a,b,d=0,1; C=1,2,3! are reacted with an alkylating agent to give insoluble monophosphonium salts of the compds. (I). The salts are hydrolyzed in alkali soln. to give title compds.

    Abstract: The invention deals with a process for preparing a diester of oxalic acid from carbon monoxide and an ester of nitrous acid in the vapor phase under a pressure in the presence of a special palladium supported catalyst. The catalyst is a solid palladium supported catalyst comprising metallic palladium or a salt thereof deposited on a nonacidic carrier, such as alpha-alumina, having a surface area of less than about 10 square meters per gram. This process provides an increased conversion to the diester product, a longer catalyst life and less by-product formation.

    Abstract: A process is provided for the utilization of dialkyl carbonates formed as by-products in a continuous process for the synthesis of oxalic acid esters from nitrous acid esters and carbon monoxide and wherein the esters are subsequently used as intermediates in the production of commercially useful products, such as ethylene glycol. The process comprises contacting a mixture containing the by-product comprised of a dialkyl carbonate with an aqueous solution of a metal carbonate under hydrolyzing conditions whereby the dialkyl carbonate is converted to the corresponding alkanol and the metal carbonate is converted to metal bicarbonate. Upon distillation of the alkanol from the mixture the bicarbonate is converted back to the metal carbonate which can then be recycled from the bottoms to the hydrolyzing zone for use in further hydrolysis of by-product. The alkanol is recycled for use in the continuous process.
