Acrylic acid is an organic compound composed of a vinyl group and a carboxyl group. It is also the simplest unsaturated carboxylic acid. Pure acrylic acid is a colorless, clear liquid with pungent smell. It can be miscible with water, alcohol, ether and chlorine. Acrylic acid is an important basic organic raw material, which is mainly used in the production of acrylic ester, super absorbent resin (SAP), special acrylate, water treatment agent, washing aid and other products. Acrylic acid has the special molecular structure of unsaturated double bond organic acids, which can be combined into thousands of polymers. In view of this, industrial enterprises, including China, generally support the construction of acrylic acid and acrylate production units to ensure the supply of raw materials for acrylate.
Analysis of upstream and downstream industrial chain of acrylic acid
The upstream raw material of acrylic acid is propylene, which is obtained from refinery and ethylene cracking unit. Downstream is mainly used for acrylate and other polyesters. Acrylic acid is mainly used to produce acrylate (resin) in industry, accounting for about 60% of the total consumption of acrylic acid. It is used in construction, papermaking, leather, textile, plastic processing, packaging materials, daily chemical industry, water treatment, oil extraction, metallurgy and other fields. Acrylic acid plays an important role in fine chemical industry. Polypropylene and acrylic acid copolymer produced from acrylic acid are used as dispersant, flocculant and thickener. It has a broad market space in various fields such as daily life and high-tech materials.
