Acetone (CH3COCH3), also known as dimethyl ketone, is the simplest saturated ketone. It is a colorless transparent liquid with a special pungent smell. Soluble in water, methanol, ethanol, ether, chloroform, pyridine and other organic solvents. It is inflammable and volatile, with active chemical properties. Acetone is an important raw material for organic synthesis, which is used to produce epoxy resin, polycarbonate, plexiglass, medicine, pesticide, etc. It is also a good solvent for coatings, adhesives, cylinder acetylene, etc. It is also used as diluent, cleaning agent and extractant. It is also an important raw material for manufacturing acetic anhydride, diacetone alcohol, chloroform, iodoform, epoxy resin, polyisoprene rubber, methyl methacrylate, etc. It is used as a solvent in smokeless gunpowder, celluloid, acetate fiber, painting and other industries. It is used as extractant in oil and other industries.

It is used to prepare important organic chemical raw materials such as plexiglass monomer, bisphenol A, diacetone alcohol, hexanediol, methyl isobutyl ketone, methyl isobutyl methanol, phorone, isophorone, chloroform and iodoform. It is used as an excellent solvent in coating, acetate fiber spinning process, acetylene storage in steel cylinder, dewaxing in oil refining industry, etc.

Role of acetone in manufacturing process：

(1) Surface cleaning

(2) Remove photoresist.

According to the current development of semiconductor chips, the finer the process, the higher the pollution control requirements for chip manufacturing. In the 80-60 nm process, the chip cleaning process is about more than 100 steps, while in the 10 nm process, the cleaning process increases sharply to more than 200 steps. Such a large amount of cleaning agent also puts forward higher requirements for the quality of acetone.

Acetone test items

Content detection, concentration detection, gas phase detection, moisture detection, furfural detection, chemical detection, insoluble matter detection, national standard detection, etc.
