Storage method

Store in a sealed, cool, dry and dark place.

Synthesis method

Obtained from the reaction of anthranilic ether and acetic anhydride. Put the measured amount of o-anisole into the reaction kettle, and add glacial acetic acid under stirring. Add acetic anhydride dropwise at 10 to 12°C, finish the addition in about 2 hours, and let it stand for 2 hours to obtain the intermediate o-acetamidoanisole for industrial use. The ingredient ratio is anthranilate: glacial acetic acid: acetic anhydride = 1:0.9:1 (weight ratio). You can also mix anthranilate and acetic anhydride, reflux in a sand bath for 2 hours, let cool, obtain needle-like crystals, filter, wash away the acidity with water, and then recrystallize with water to obtain the finished product.

Purpose

1. Organic synthesis. Used as raw material for organic synthesis, used in the manufacture of pesticides, medicines, etc. Preparation of aniline yellow and other dyes.
