Methyl anthranilate Use

Methyl anthranilate (Methylanthranilate or Methyl2-aminobenzoate) naturally exists in the essential oils of citrus, tuberose, jasmine, gardenia, orange blossom, etc. It has a strong fruity and floral aroma and is one of the backbone products of the fragrance industry. It is widely used in daily flavors and food flavors. In food flavors, it is the main flavor of grape flavor, and it can also be used in various fruity flavors such as berry, melon, honey, citrus, lemon, strawberry and pineapple. About 60 kinds of spices can also be prepared from methyl anthranilate, for example, other anthranilate esters prepared by transesterification of methyl anthranilate are one of the commonly used raw materials for perfumery, with wide application and high value ; It undergoes condensation reaction with some aldehydes to generate Schiff base with more stable properties and richer aroma, which is a good fixative in essence.

Methyl anthranilate Production method

In nature, methyl anthranilate is found in tower flower oil, orange flower oil, ylang ylang ylang, jasmine oil, tuberose oil, etc. Industrial manufacturing is generally obtained by esterification of o-aminobenzoic acid and methanol. Heat the methanol solution of o-aminobenzoic acid to 65 ℃, drop sulfuric acid, and react at 75 ℃ to generate sulfate of methyl o-aminobenzoate. Then neutralize with sodium hydroxide solution to precipitate methyl anthranilate. Extract with toluene, wash the toluene extraction solution and evaporate the toluene, then distill the crude methyl o-aminobenzoate under reduced pressure in the presence of sodium carbonate, cool the finished distillate to below 12-15 ℃, and then the methyl o-aminobenzoate is separated out. Another preparation method is to obtain this product from phthalic anhydride through ammoniation, degradation and esterification.
