Abstract
Tris(2-acetoacetoxy ethyl)-amine, and its hydrosoluble mineral or organic acid salts, preparation process, use as formaldehyde collectors, and finishing process for fabrics based on cellulose fibres.
Claims5
Tris(2-acetoacetoxy ethyl)-amine or its hydrosoluble mineral or organic acid salts.
Preparation process for tris(2-acetoacetoxy ethyl)-amine, or its mineral or organic acid salts, characterized in that 2,2,6-trimethyl-oxo-l,3-dioxine is reacted with triethanolamine in order to obtain tris(2-acetoacetoxy ethyl)-amine which optionally is salified.
A process for finishing cellulose containing fibers which comprises placing the fibers in an aqueous finishing bath which contains an aminoplastic resin, the improvement comprising adding an effective amount of tris(2-acetoacetoxy ethyl)-amine or one of its hydrosoluble mineral or organic acid salts to act as a formaldehyde collector.
A process for collecting formaldehyde which is present in cellulose containing fibers comprising applying to said fibers an effective amount of an aqueous solution of tris(2-acetoacetoxy ethyl)-amine or one of its hydrosoluble mineral or organic acid salts.
