Description

Ethyl acetate is widely used as a solvent in cleaning of the circuit board. It is most suited for HPLC instruments and spectrophotometers including the UV-visible spectrophotometer, the IR spectrometer and the mass spectrometer. In addition, it can also be used as a solvent in column chromatography and solvent extraction. It is also used in glues, nail polish removers, decaffeinating tea and coffee and in cigarettes. It is present in confectioneries, perfumes and fruits.

Ethyl acetate application in Decaffeination Industry


· Cleaning Solvent: It is used to clean circuit boards and electronic components because of its ability to dissolve residues without damaging the components.

· Precision Cleaning: In precision cleaning operations, ethyl acetate is valued for its fast evaporation rate, leaving behind no residue on optical devices, mechanical parts, and sensitive electronics.

· Degreasing: Its solvency power is employed in degreasing metals and plastics, preparing surfaces for further processing or finishing.
