About esters; phosphite esters and their salts; their halogenated, sulphonated, nitrated or nitrosated derivatives, diethyl phosphite

HS code 292022 covers a range of organic chemical compounds known as esters, phosphite esters, and their derivatives. These compounds are widely used in various industries, including agriculture, pharmaceuticals, and plastics manufacturing. They play a crucial role in the production of pesticides, lubricants, and other essential products, making them an important part of the global chemical industry.

Production process

The production of the compounds covered by HS code 292022 typically involves a series of chemical reactions. The key steps often include the esterification of alcohols with phosphoric acid or its derivatives, as well as the halogenation, sulfonation, nitration, or nitrosation of the resulting esters. These processes are carried out in specialized chemical plants using a range of equipment, such as reactors, distillation columns, and purification systems.

Production inputs

The main inputs required for the production of the compounds under HS code 292022 include alcohols, phosphoric acid, and various halogenating, sulfonating, nitrating, or nitrosating agents. Additionally, the industry relies on a range of specialized equipment, such as chemical reactors, distillation columns, and purification systems. The availability of these raw materials and technological resources is crucial for the efficient and sustainable production of these essential chemical compounds.

Production outputs

The compounds covered by HS code 292022 are used as intermediates in the production of a wide range of other chemical products. For example, the esters and phosphite esters may be used in the manufacture of 290920 (Ethers, ether-alcohols, ether-phenols, ether-alcohol-phenols, alcohol peroxides, ether peroxides, ketone peroxides (whether or not chemically defined), and their halogenated, sulphonated, nitrated or nitrosated derivatives), 380810 Insecticides, rodenticides, fungicides, herbicides, anti-sprouting products and plant-growth regulators, disinfectants and similar products, and 390690 Acrylic polymers in primary forms.
