Acetonitrile is a commonly used polar aprotic solvent. In inorganic chemistry, acetonitrile is widely used as a ligand, and its abbreviation is MeCN. For example, acetonitrile complex PdCl2 (MeCN) 2 c

Acetonitrile is a stable compound, which is not easy to be oxidized or reduced, but there is a three bond between carbon and nitrogen, which is prone to addition reaction. In the presence of acid or b

Acetonitrile HPLC grade small. In the commercial HPLC and superior absorption spectra of acetonitrile and methanol, the absorption Z of acetonitrile HPLC is small (especially in the short wavelength).

Precautions for acetonitrile operation: strictly seal, provide sufficient local exhaust and comprehensive ventilation. The operation should be mechanized and automated as much as possible. Operators m

Health hazards of isopropanol: When exposed to high concentration steam, headache, sleepiness, ataxia and eye, nose and throat irritation symptoms occur. Oral administration can cause nausea, vomiting

Tetrahydrofuran (THF) is a colorless organic liquid that is miscible with water and has a small viscosity under normal temperature and pressure. The chemical formula of this cyclic ether can be writte

Acetonitrile is a toxic and flammable colorless transparent liquid, so we must pay attention to safety during transportation. During the transportation of acetonitrile, the transportation vehicles sha

Invasion route: inhalation, ingestion, skin absorption. Health hazards: acute acetonitrile poisoning occurs more slowly than hydrocyanic acid, with a incubation period of several hours. The main sympt

Method of recovering tetrahydrofuran: the waste liquid containing tetrahydrofuran is distilled and concentrated for many times to gradually increase the content of tetrahydrofuran, and then dehydrated

1. Used as solvent and raw material for organic synthesis. 2. Used as chromatographic reagent, organic solvent and nylon 66 intermediate. Tetrahydrofuran, also known as monocyclopentadecane, oxyhetero

1. Respiratory system protection: filter gas mask (half mask) should be worn when it may be exposed to its vapor. If necessary, it is recommended to wear self-contained breathing apparatus. 2. Eye pro

The acetonitrile manufacturer tells you the precautions for acetonitrile operation: strictly seal it, and provide sufficient local exhaust and comprehensive ventilation. The operation should be mechan
