2- STABILIZATION OF TRIS2-HYDROXYETHYLMETHYLAMMONIUM HYDROXIDE AGAINST DECOMPOSITION WITH DIALKYHYDROXYLAMINE

摘要

The present invention provides a stabilized solution useful as a raw material for various applications and a method of stabilizing such aqueous solution with a stabilizer comprising at least one dialkylhydroxylamine or an inorganic or organic acid salt thereof. Methods for stabilizing the stabilized solution and its aqueous solution include, for example, those relating to tris (2-hydroxyethyl) methylammonium hydroxide (THEMAH) and / or carbohydrazide (CHZ).
