Open the CIPO recordAbstract From the Canadian patent
Organometalates are prepared by the reaction, in a liquid reaction menstruum between a, soluble salt of an organic-containing cation and a heavy metal salt, e.g. silver salt, of a metalate to product a soluble organometalate and a substantially insoluble heavy metal salt. The heavy metal salt of the metalate may be substantially insoluble in the reaction menstruum. The organometalates are useful to enhance the selectivity to monoalkylene glycols when provided in processes for the hydrolysis of alkylene oxides. D-14292
