About anionic organic surface-active agents (other than soap); linear alkylbenzene sulphonic acids and their salts, whether or not put up for retail sale

HS code 340231 covers a crucial class of chemical compounds known as anionic organic surface-active agents, which are widely used in a variety of industrial and consumer applications. These surface-active agents, including linear alkylbenzene sulphonic acids and their salts, play a vital role in the formulation of detergents, cleaners, and other cleaning products. Their ability to lower the surface tension of liquids makes them indispensable in industries ranging from textile processing to oil recovery, contributing significantly to the global economy.

Production process

The production of anionic organic surface-active agents under HS code 340231 typically involves a multi-step process. The key steps include the alkylation of benzene to form linear alkylbenzenes, followed by sulfonation to create the linear alkylbenzene sulphonic acids. These acids are then neutralized with various salts, such as sodium or potassium, to produce the final anionic surfactant products.

Production inputs

The main inputs required for the production of HS code 340231 products include benzene, linear olefins, and sulfuric acid as the primary raw materials. Additionally, specialized equipment such as reactors, distillation columns, and mixing tanks are necessary for the various stages of the production process. Energy sources, such as steam or electricity, are also crucial inputs to power the manufacturing operations.

Production outputs

The primary outputs of HS code 340231 are anionic organic surface-active agents, including linear alkylbenzene sulphonic acids and their salts. These surfactants find widespread application in the formulation of 340211 Anionic organic surface-active agents, whether or not put up for retail sale, 340219 Anionic organic surface-active agents, whether or not put up for retail sale, and 340220 Preparations put up for retail sale, among other related product categories.
