29143990 is a subcategory of the Harmonized System of Nomenclature (HSN) code that refers to “Other aromatic ketones without other oxygen function.” Ketones are a type of organic compound that contain a carbonyl group, which is a carbon atom double-bonded to an oxygen atom. Aromatic ketones, in particular, contain an aromatic ring structure in addition to the carbonyl group
- This HSN code includes ketones that have an aromatic ring structure but do not contain any other oxygen functional groups such as hydroxyl (-OH) or carboxyl (-COOH) groups.
- Examples of aromatic ketones that fall under this code include acetophenone, benzophenone, and fluorenone.
- Aromatic ketones have various applications in the chemical industry, including as solvents, intermediates in the synthesis of other organic compounds, and components of perfumes and flavors.
- The properties of aromatic ketones can vary depending on the specific compound, but they generally have a characteristic sweet odor and are soluble in organic solvents such as ethanol and acetone.
- Aromatic ketones can be synthesized through various methods, including Friedel-Crafts acylation and oxidation of aromatic hydrocarbons.
