Solvent Yellow 98 - Uses and synthesis methods
Introduction
Solvent Yellow 98 is a fluorescent green yellow dye with excellent light resistance and temperature resistance. It can be used for coloring various plastics, PS, SAN, PC, PETP and PBTP, PMMA, PA6, PA66 and hard PVC.
production method
4-nitro -1, 8-naphthalene dimethyl anhydride, o-aminothiophenol and octaamine are used as raw materials. First, 4-nitro -1, 8-naphthalene dimethyl anhydride is condensed with o-aminothiophenol to prepare thioether compounds, and then condensed with decaamine to prepare naphthalene dimethyl imide intermediate, and finally The free amino group in the molecule is diazotized, closed in the presence of copper sulfate, and the product is obtained after liquid alkali treatment. The finished product is filtered, dried and crushed.
