38. Liquid phase standard��It can be used as a cleaning agent in the textile industry, as a flavor extractant for special modified alcohols in the food industry, and as an extractant for pharmaceutical processes and organic acids. It is an important spice additive in the spice industry and can be used as a component of flavoring agents. Ethyl acetate is also a raw material for the manufacture of dyes, drugs and fragrances. 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 reagents, chromatographic analysis standard materials and solvents
