analyzed by icp for molybdenum and other metals the dried solid was analyzed by icp for metal impurities some of the solid samples were also analyzed for the amount of moo 2 and moo 3 a 20 g sample of the technical oxide was suspended in 60 g of water concentrated sulfuric acid 10 g was added and the mixture was heated to 60 u00b0 c after stirring the mixture for 30 minutes at 60 u00b0 c chlorine 3 6 g was slowly bubbled through the mixture over a period of 40 minutes the gray slurry became light green the mixture was heated to 90 u00b0 c and stirred at 90 u00b0 c for 30 minutes nitrogen was bubbled through the mixture at 90 u00b0 c for 30 minutes to strip off any unreacted chlorine the mixture was cooled to room temperature the slurry was then filtered under suction and washed with 20 g of 2 hydrochloric acid and 20 g of water the wet cake 22 6 g was dried in an oven at 90 u00b0 c for 15 hours to yield 16 8 g of product a slurry of 50 g of the same technical oxide used in example 1 was formed in 95 g of water was stirred at 60 u00b0 c for 30 minutes chlorine 6 8 g was bubbled through the slurry for about 40 minutes maintaining a positive pressure of.
