Storage method
This product should be stored sealed in a dry and dark place.
Synthesis method
1. Phthalic anhydride is first condensed with p-chlorobenzene, and then condensed with p-toluidine for a second time, and then through; grinding; drying and commercialization chemical treatment to obtain products.
2.Mainly use the contraction method. It is obtained by performing a condensation reaction of aniline, hydrochloric acid and nitrobenzene, then adding hydrochloric acid and sodium hydroxide for acid-base leaching, and then beating and drying.
Purpose
1. Mainly used for dyeing pure polyester, and can also be used for dyeing acetate fiber. Can also be used for direct printing and transfer printing. Often combined with dispersed red 3B and dispersed yellow RL to form the three primary colors. Reactive dyes or direct dyes can be used to dye polyester/viscose blended fabrics in the same bath.
2.Mainly used for coloring polystyrene, ABS, rigid PVC resin, and also used for coloring polyester fiber pulp. Used in cosmetic coloring.
