Abstract: 11,430 PROCESS FOR PRODUCING BIS(N,N-DIALKYLAMINO)ALKYL ETHERS A process is provided for producing bis-(N,N-dialkylamino)alkyl ethers of the formula (R2NR')2O, wherein R is a methyl or ethyl group and R' is a bivalent alkylene group having from 2 to 3 carbon atoms. The novel process is effected by a two-step, "one pot" reaction that utilizes SO3 vapor and R2NR'ONa as reactants, wherein R and R' are defined above. The resulting bis-ethers are useful as catalysts in the production of polyurethanes, especially cellular polyurethanes. S P E C I F I C A T I O N

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.

Abstract: 12,133 NEW PROCESS FOR PREPARING BIS(N,N-DIALKYLAMINO)ALKYL ETHERS A process is provided for producing bis-(N,N-dialkylamino)alkyl ethers of the formula (R2NR')2O, wherein R is a methyl or ethyl group and R' is a bivalent alkylene group having from 2 to 3 carbon atoms. The novel process is effected by a two-step, "one pot" reaction that utilizes a chloro-containing compound selected from the group consisting of sulfuryl chloride, thionyl chloride and chlorosulfonic acid together with R2NR'ONa as reactants, wherein R and R' are defined above. The resulting bis-ethers are useful as catalysts in the production of polyurethanes, especially cellular polyurethanes. S P E C I F I C A T I O N
