Solvent Red 49 Use and Manufacturing

Methods of Manufacturing

Using 2-hydroxy-N, N-diethylaniline and phthalic anhydride as raw materials, the two are condensed in the presence of sulfuric acid, and the product is obtained by alkali dissolution and acid dissolution. After filtering and drying, the finished product is obtained.

Uses

Oil-soluble red BN is used for coloring of grease, candles, rubber, plastics and transparent paint.
