| abstract |
1,148,337. Anhydrous monomeric glyoxal. IMPERIAL CHEMICAL INDUSTRIES Ltd. 8 April, 1968 [3 May, 1967], No. 20611/67. Heading C2C. Anhydrous monomeric glyoxal is prepared by heating hydrated glyoxal suspended in a silicone fluid at a temperature in the range 120-185‹ C. to evaporate a mixture comprising glyoxal and water vapour and removing the water from the vapour mixture e.g. by condensation. The vapour may be dried further by a molecular sieve or a dehydrating agent. The process may be carried out at reduced pressure. |
