Acetic acid Acetic acid Acetic acid , systematically named ethanoic acid , is a colourless liquid organic compound with the chemical formula CHCOOH (also written as CHCOH or CHO). When undiluted, it is sometimes called "glacial acetic acid". Vinegar is no less than 4% acetic acid by volume, making acetic acid the main component of vinegar apart from water. Acetic acid has a distinctive sour taste and pungent smell. In addition to household vinegar, it is mainly produced as a precursor to polyvinyl acetate and cellulose acetate. It is classified as a weak acid since it only partially dissociates in solution, but
Nitrosylsulfuric acid organic chemistry to prepare diazonium salts from amines. Related NO-delivery reagents include nitrosonium tetrafluoroborate ([NO]BF) and nitrosyl chloride. Nitrosylsulfuric acid is a hazardous material and precautions are indicated. Nitrosylsulfuric acid Nitrosylsulfuric acid is the chemical compound with the formula NOHSO. It is a colourless solid that is used industrially in the production of caprolactam, and was formerly part of the lead chamber process for producing sulfuric acid. The compound is the mixed anhydride of sulfuric acid and nitrous acid. In organic chemistry, it is used as a reagent for nitrosating, as a diazotizing agent, and as an oxidizing agent. A
