Direct Yellow 66 Chemical Properties,Uses,Production
Preparation
4-Nitrobenzenamine diazo, coupled with 2-Hydroxybenzoic acid, will the nitro reduction, and 4-Nitrobenzoyl chloride condensation , then the nitro reduction nitride pay equal attention to, and 1-(3-Nitrophenyl)-3-carboxy-5-pyrazolone?coupling and will last a nitro reduction.
Properties and Applications
yellow. Moderate soluble in water for yellow orange, hardly soluble in alcohol. The strong sulfuric acid in orange, yellow for diluted. The dye solution to join strong hydrochloric acid colour and lustre is obvious change; Add thick sodium hydroxide solution without change color. Used for cellulose d dyeing and printing, dyeing copper, iron ion in the same light
