Title (EN) USING NOVEL AMINES TO STABILIZE QUATERNARY TRIALKYLALKANOLAMINES
(FR) UTILISATION DE NOUVELLES AMINES POUR STABILISER DES TRIALKYLALCANOLAMINES QUATERNAIRES
Abstract: front page image
(EN)New stabilizers for solutions of choline hydroxide and related quaternary trialkylalkanolamines are disclosed. The stabilizers are alkyl hydroxylamines, hydrazines, hydrazides, or derivates thereof, including compounds containing more than one such functionality. The new stabilizers are effective at concentrations less than about 1000 ppm, and choline hydroxide solutions stabilized with the compounds described herein typically have Gardner Color change less than about 2.0 after six months at reasonable temperatures.
(FR)La présente invention concerne de nouveaux stabilisants pour des solutions d'hydroxyde de choline et de trialkylalcanolamines quaternaires apparentées. Les stabilisants sont des alkyl-hydroxylamines, hydrazines, hydrazides, ou leurs dérivés, y compris des composés contenant plus d'une fonctionnalité de ce type. Les nouveaux stabilisants sont efficaces à des concentrations inférieures à environ 1000 ppm, et les solutions d'hydroxyde de choline stabilisées avec les composés décrits dans ce document présentent généralement un changement de couleur Gardner inférieur à environ 2,0 après six mois à des températures raisonnables.
