1.Methyl acetate is a fast drying solvent of nitrocellulose and cellulose acetate, which is used in paints and coatings.

2. It is also used in the manufacture of artificial leather and spices and as an extractant of oil.

3.It is also a raw material for making dyes .

4. In the experimental study, it is used as standard material and solvent for chromatographic analysis, and also used for the separation of lithium chloride from alkali metal chloride and the synthesis of spices.

Methyl acetate is an important solvent and organic chemical raw material. It is used in Production of oil and diesel. High-purity methyl acetate is also widely used in the synthesis of acetic acid, acetic anhydride, methyl acrylate, vinyl acetate and acetamide. The carbonylation of methyl acetate to produce acetic anhydride is currently the most economical process for producing acetic anhydride, and its market application prospects are very broad. The market price of high-purity methyl acetate is 2~4 times higher than low-purity methyl acetate. Therefore, the production of high-purity methyl acetate has greater economic benefits.
