Ethyl acetate is one of the most widely used fatty acid esters. It is a quick-drying solvent with excellent solubility. It is an excellent industrial solvent and can also be used as an eluent for column chromatography. It can be used for nitrocellulose, ethylcellulose, chlorinated rubber and vinyl, cellulose acetate, cellulose butyl acetate and synthetic rubber. It can also be used for liquid nitrocellulose ink for copy machines. It can be used as a solvent for adhesives and a thinner for spray paint. Ethyl acetate is an efficient solvent for many types of resins, and is widely used in the production of inks and artificial leather. Used as analytical reagent, chromatographic analysis standard substance and solvent.
Main uses Its main uses are: as an industrial solvent, used in coatings, adhesives, ethyl cellulose, artificial leather, linoleum colorants, man-made fibers and other products; as an adhesive, used in the production of printing ink, artificial pearls ; As an extractant, it is used in the production of medicines, organic acids and other products; As a spice raw material, it is used as the main raw material for fruit flavors such as pineapple, banana, strawberry and spices such as whiskey and cream. Used as a solvent, and in the synthesis of dyes and some pharmaceutical intermediates. It is one of the most widely used synthetic spices in food flavors, and is widely used in the deployment of flavor food flavors such as bananas, pears, peaches, pineapples, and grapes. It is a quick-drying solvent for nitrocellulose, ethyl cellulose, cellulose acetate and neoprene, and a low-toxicity solvent for industrial use. It can also be used as a cleaning agent in the textile industry and an extractant of natural fragrances, and is also an important raw material for the pharmaceutical industry and organic synthesis.
