ABSTRACT:
Glyoxal is prepared by oxidizing glycol in the presence of a silver catalyst of a defined particle size and under defined conditions of temperature, residence time and inert gas concentration.
The glyoxal obtainable by the process of the invention may be used in wrinkle-resist finishing, as an assistant for increasing the tensile strength and resilience of fibrous materials, a tanning agent, a hardener in the photographic industry, and a starting material for the manufacture of synthetic resins, textile auxiliaries, for example to prevent shrinkage after washing, paper additives, for example for increasing the wet strength, and plastics.
