Application of high-purity Acetonitrile

1.High-purity Acetonitrile reagentacetonitrile application company -Yuanfarchemical

Production of high purity Acetonitrile, must ensure purity ≥99.9%, water ≤100ppm, metal ion content ≤10ppb, the number of dust particle size greater than 0.2μm of less than 400/ml. Acetonitrile for different uses have different requirements of impurities content, can be divided:MOS (Metal-Oxide-Semiconductor) grade,VLSI (very large scale integration) grade, HPLC (High Performance Liquid Chromatography) grade and analytical, spectral pure.

2.Used for chemical analysis and instrumental analysis

Recently Acetonitrile as an organic modifier and solvent used in thin layer chromatography, paper chromatography, spectrum and polarographic analysis.Since pure Acetonitrile does not absorb ultraviolet light at 200nm~400nm, therefore, it is to open up the use of as a solvent in high performance liquid chromatography.With the popularity of this testing technology, HPLC grade Acetonitrile demand growth year after year.

3.Used as the semiconductor cleaning agent in the microelectronics industry

Conventional semiconductor cleaning agent has been using hydrochloric acid, sulfuric acid, nitric acid, hydrogen peroxide, toluene, etc., these agents have strong corrosive effect, low cleaning efficiency, poor results.Because Acetonitrile is a polar organic solvents, has good solubility to oils, salts and a polymer compound, can wash away grease, wax, fingerprints, corrosive and flux residues on the silicon wafer and the like. So we began using high-purity Acetonitrile as semiconductor cleaning agent.

YUANFAR CHEMICAL have been engaged in chemical business since 2001, and has our own factories  manufacturing hydrazine product
