HS v2022 Code: 291423
About ketones; cyclanic, cyclenic or cycloterpenic, without other oxygen function, ionones and methylionones
HS code 291423 covers a group of organic compounds known as ketones, specifically those with a cyclanic, cyclenic, or cycloterpenic structure, without any other oxygen function. This class of chemicals is widely used in the production of fragrances, flavors, and various industrial applications. As a key component in the global chemical industry, the 291423 product group plays a vital role in the broader economy, contributing to the manufacturing of a diverse range of consumer and industrial goods.
Production process
The production of ketones under HS code 291423 typically involves a multi-step process. The starting point is the selection of appropriate raw materials, which may include various cyclic hydrocarbons. These are then subjected to oxidation reactions, often using catalysts, to introduce the ketone functional group. Purification and separation techniques, such as distillation or crystallization, are then employed to obtain the desired ketone compounds in high purity.
Production inputs
The main inputs required for the production of 291423 ketones include cyclic hydrocarbon feedstocks, oxidizing agents, catalysts, and various processing equipment such as reactors, distillation columns, and purification systems. The specific raw materials and production methods may vary depending on the target ketone compound and the desired purity levels.
Production outputs
The primary outputs of HS code 291423 are a diverse range of ketone compounds, including ionones and methylionones, which are widely used in the fragrance and flavor industries. These ketones may also find applications in the production of 291521 Acyclic aldehydes without other oxygen function, 291529 Cyclic aldehydes without other oxygen function, and 291700 Halogenated, sulfonated, nitrated or nitrosated derivatives of hydrocarbons, among other related chemical products.
