Ethyl acetate Application:
1,It is widely used in the production of ink, adhesive and artificial leather,
as well as the extraction agent of pharmaceutical and organic acids,
and as the component of varnish and perfume.
2,It can be used to dissolve nitrocellulose, ink, grease, etc.
It can also be used for raw materials such as paint,
artificial leather, plastic products, dyes, medicines and spices.
3,Used as a seasoning for feed.
production method of Ethyl acetate :
1.Calcined from zinc carbonate.Acetic acid and methanol were directly esterified with sulfuric
acid as catalyst to Acetic acid and ethanol were heated and esterified in the presence of sulfuric acid,
neutralized and dehydrated by sodium sulfonate, and then rectified.
2.Sodium acetate or potassium acetate and ethanol are distilled in the presence of sulfuric acid.
3.Acetaldehyde is polymerized in the presence of lead alcohol or lead acetate catalyst.
Storage condition:Warehouse ventilation and low temperature drying;
Store separately from oxidizer.
