About esters of other inorganic acids of non-metals (other than of hydrogen halides) and their salts, their halogenated, sulphonated, nitrated or nitrosated derivatives

HS code 2920 covers a diverse range of organic compounds known as esters of other inorganic acids of non-metals. These compounds play a crucial role in various industries, including pharmaceuticals, agrochemicals, and specialty chemicals. They are valued for their unique properties and versatility, making them essential building blocks for a wide array of products that impact our daily lives.

Production process

The production of HS 2920 compounds typically involves a multi-step chemical synthesis process. This often begins with the reaction of an inorganic acid, such as phosphoric acid or sulfuric acid, with an alcohol or phenol. The resulting ester is then subjected to further modifications, such as halogenation, sulfonation, nitration, or nitrosation, to produce the desired derivatives. Advanced techniques, including distillation, crystallization, and purification, are employed to ensure the high quality and purity of the final products.

Production inputs

The main inputs required for the production of HS 2920 compounds include a variety of inorganic acids, alcohols, and other organic precursors. Specialized equipment, such as reactors, distillation columns, and purification systems, are also essential for the manufacturing process. Additionally, skilled personnel with expertise in organic synthesis and chemical engineering are crucial for the efficient and safe production of these compounds.

Production outputs

The diverse range of HS 2920 compounds find applications in numerous industries. They are used as intermediates in the production of 2921 Amine-function compounds, 2922 Oxygen-function amino-compounds, and 2924 Carboxyamide-function compounds; amide-function compounds of carbonic acid, among others. These esters and their derivatives are also utilized in the formulation of various 3002 (Human blood; animal blood prepared for therapeutic, prophylactic or diagnostic uses; antisera, other blood fractions and immunological products, whether or not modified or obtained by means of biotechnological processes; vaccines, toxins, cultures of micro-organisms (excluding yeasts) and similar products), 3808 Insecticides, rodenticides, fungicides, herbicides, anti-sprouting products and plant-growth regulators, disinfectants and similar products, and 3824 (Prepared binders for foundry moulds or cores; chemical products and preparations of the chemical or allied industries (including those consisting of mixtures of natural products), not elsewhere specified or included).
