synthetic route
The industrial synthesis of methyl ortho aminobenzoate is mainly achieved through chemical synthesis methods, rather than direct extraction from plants. The common routes are as follows:
Esterification of ortho aminobenzoic acid with methanol: Under the action of acidic catalyst (such as concentrated sulfuric acid), ortho aminobenzoic acid undergoes esterification reaction with methanol to produce ortho aminobenzoic acid methyl ester.
Reduction method of methyl ortho nitrobenzoate: First, methyl ortho nitrobenzoate is reduced to methyl ortho aminobenzoate, which is suitable for production with high purity requirements
This compound naturally exists in plants such as grapes, citrus, and jasmine, but due to high demand, industrial production mainly relies on synthetic routes
