Product use:

The molecular structure of the pigment is trans isomer, giving red light orange. Hostaperm Orange GR has a specific surface area of 46 m2 / g. Light and weather fastness grade 7-8. Used for the coloring of acrylonitrile (PAN) puree (cloth, canvas, and tent), transparent polystyrene coloring, soluble in thermoplastic polyester to give a yellow color; metallic luster in paint with metallic aluminum paste; acid / alkali resistance Excellent, also suitable for outdoor latex paint coatings.

Synthesis principle:

Condensation reaction of 1,4,5,8-naphthalenetetracarboxylic acid with o-phenylenediamine at 120 ° C in glacial acetic acid medium to generate cis (blue-red) and trans (yellow-red) The mixture was separated by means of different solubility in potassium hydroxide-ethanol solution, heated at 70 ° C for 1H, the trans isomer was precipitated, filtered, and the crude pigment was hydrolyzed to prepare CI Pigment Orange 43 by pigmentation treatment.
