Abstract: A PROCESS FOR THE PREPARATION OF FAST DYEINGS AND PRINTS ON FIBROUS MATERIALS CONTAINING HYDROXY GROUPS OR NITROGEN, WHICH PROCESS COMPRISES APPLYING WATER-SOLUBLE ORGANIC DYESTUFFS WHICH CONTAIN AT LEAST A GROUP OF THE FORMULA

-SO2-CH2-CH2-O-CO-NH-X

IN THE MOLECULE IN WHICH GROUP X IS A HYDROGEN ATOM OR AN -SO3H- GROUP ON THE SAID FIBROUS MATERIALS AND FIXING THEM AT NORMAL OR AT ELEVATED TEMPERATURE OR UNDER THE ACTION OF HEAT YIELDING VERY VALUABLE, INTENSE DYEINGS AND PRINTS WICH ARE VERY STABLE WHEN BEING SUBJECTED TO TREATMENTS OF WASHING AND TO THE ACTION OF LIGHT. THEY HAVE ALSO A REMARKABLE FASTNESS TO WATER, SEAWATER, RUBBING, IRONING, ACIDS, ALKALIS AND SOLVENTS. WHEN BEING FINISHED AFTERWARDS WITH SYNTHETIC RESINS IN AN ACID MEDIUM, DYEINGS AND PRINTS OF THE INVENTION SHOW ADVANTAGEOUS PROPERTIES.

Abstract: N-acetoacetyl-2,5-dimethoxy-4-chloroanilide is obtained in high yield and purity by suspending 2,5-dimethoxy-4-chloroaniline in water and adding the complete amount of diketene necessary altogether at the beginning of the reaction. The product is obtained in a purity allowing its use as an azoic coupling component without purification.
