Description

Technical Field

[0001] The present invention relates to the technical field of chemical purification, and in particular to methyl acetate purification equipment and process. Background Art

[0002] Methyl acetate, also known as methyl acetate, is a colorless, transparent, aromatic liquid with excellent solubility, quick drying properties, and low toxicity. It is an important organic solvent and chemical raw material. As a solvent, it is widely used in the production of resins, coatings, inks, paints, adhesives, and leather. High-purity methyl acetate can be used as a raw material to produce polyesters, acetic anhydride, and acetamide. The current market demand is large and the price is high, so the production of high-purity methyl acetate has great economic benefits. The existing methyl acetate is only processed by a single stirring process, resulting in uneven heating and distillation effects at the bottom and top of the stirring tank, resulting in low purification efficiency. To this end, we have proposed a methyl acetate purification equipment and process. Summary of the Invention

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:
