Abstract
PURPOSE: To provide a stabilizing agent containing an aluminum compound as a main component, and useful for suppressing the decomposition of an aqueous solution containing 2-aminocyclohexanone oxime (Amox) or its salt useful as a raw material for the preparation of an essential amino acid,(L-lysine, etc.).
CONSTITUTION: The decomposition of Amox is suppressed effectively by adding 5W5,000ppm of an aluminum compound (e.g. aluminum chloride, aluminum sulfate, aluminum acetate, etc.) as a stabilizer to Amox.
EFFECT: The agent exhibits higher effectivity in the basic range in which Amox is unstable or in the presence of iron which accelerates the decomposition of Amox. It is also effective to flocculate and precipitate the impurities and to remove from the system. The turbidity of the solution is decreased, the transmittance of the visible light is increased, and the purifying effect is also improved.
