Acids; unsaturated acyclic monocarboxylic, cyclic monocarboxylic, their anhydrides, halides, peroxides and peroxyacids; their halogenated, sulphonated, nitrated or nitrosated derivatives
In plain English
This category covers various organic acids, including unsaturated chain-like or ring-shaped monocarboxylic acids, along with their related forms such as anhydrides, halides, peroxides, and peroxyacids. It also includes derivatives of these acids that have been halogenated, sulphonated, nitrated, or nitrosated. The specific types are distinguished by their chemical structure, such as acrylic, methacrylic, oleic, linoleic, or linolenic acids, as well as aromatic acids like benzoic and phenylacetic acid. Specific items like binapacryl and benzoyl peroxide are listed separately from other acids that do not fit into the more specific categories.
