Acids; acyclic polycarboxylic acids; maleic anhydride

HS v2017 Code: 291714

About acids; acyclic polycarboxylic acids; maleic anhydride

HS code 291714 covers a range of acyclic polycarboxylic acids, including maleic anhydride. These chemicals are essential building blocks for a variety of industries, from plastics and resins to pharmaceuticals and agricultural products. As a key component in the production of many common consumer and industrial goods, the 291714 industry plays a vital role in the global economy.

Production process

The primary production method for the chemicals under HS code 291714 is catalytic oxidation. Hydrocarbon feedstocks, such as benzene or butane, are oxidized in the presence of a catalyst to produce the desired polycarboxylic acids and maleic anhydride. The specific reaction conditions, including temperature, pressure, and catalyst composition, are carefully controlled to optimize yield and product quality.

Production inputs

The main inputs for the 291714 industry include hydrocarbon feedstocks, catalysts, and energy sources. Common feedstocks are benzene, butane, and other light hydrocarbons. Catalysts, such as vanadium or molybdenum compounds, are critical to the oxidation process. Significant energy inputs, in the form of heat and electricity, are also required to power the production facilities.

Production outputs

The primary outputs of the 291714 industry are maleic anhydride and various acyclic polycarboxylic acids. These chemicals are then consumed by a wide range of downstream industries, including 390110 Polyethylene, having a specific gravity of less than 0.94, in primary forms, 390120 Polyethylene, having a specific gravity of 0.94 or more, in primary forms, and 300490 Medicaments consisting of mixed or unmixed products for therapeutic or prophylactic uses, put up in measured doses or in forms or packings for retail sale, among others.
