Read： 654 Time：20months ago Source：Transform the World with Simplicity

In the field of raw materials for chemical production, AA (acrylic acid) and its related products are very important organic compounds. AA plays an important role in the chemical industry because of its many unique properties and wide range of uses. This article will explore the nature and uses of AA and related products in detail.

1. the nature of AA

1. physical properties: acrylic acid is a colorless transparent liquid, a pungent smell. It has a higher boiling point, a higher density than water, and is insoluble in water, but soluble in organic solvents.
2. chemical properties: acrylic acid has a very active double bond and carboxyl, prone to addition, polymerization, esterification and other reactions.

2. the use of AA

1. Polymer manufacturing: Acrylic acid is an important monomer for the manufacture of many polymers, such as polyacrylic acid, polyacrylate, etc. These polymers have excellent properties and are widely used in coatings, adhesives, fibers and other fields.
2. Surfactants: Acrylic acid can be used to make surfactants, such as anionic, nonionic, and cationic surfactants. These surfactants have excellent wetting, emulsifying and dispersing properties, and are widely used in daily chemical, textile, petroleum and other industries.
3. Water treatment agent: Acrylic acid and its salts can be used as water treatment agents for adjusting the pH value of water, inhibiting scale formation, dispersing suspended solids, etc.

3. the properties and uses of AA related products

1. Acrylate: Acrylate is a compound produced by esterification of acrylic acid and alcohols. Acrylate has excellent light resistance, weather resistance, chemical resistance and other properties, widely used in coatings, adhesives, plastics and other fields.
2. Acrylic emulsion: Acrylic emulsion is an aqueous dispersion system composed of acrylic acid and other monomers. It has excellent water resistance, weather resistance, chemical resistance, etc., and is widely used in architectural coatings, textile printing and dyeing, leather processing and other industries.
3. methyl methacrylate (MMA): methyl methacrylate is an important derivative of acrylic acid, with high molecular weight, high transparency, high hardness and other characteristics, widely used in the manufacture of organic glass, plastic products, coatings and other fields. The production process of

4. AA
the production process of
AA mainly includes acetylene method, acrylonitrile method and ethylene method. Among them, the acetylene method is the most widely used method at home and abroad, it is acetylene, formaldehyde and catalyst as raw materials, through oxidation, absorption, distillation and other processes to produce acrylic acid.

5. the market prospect of AA

With the continuous development of science and technology, AA and its related products are more and more widely used in the field of chemical production raw materials, and the market demand is also increasing year by year. In the future, with the improvement of environmental protection awareness and the development of new energy industry, the market prospect of AA and its related products will be broader.

In short, AA and its related products have a very important position and role in the field of chemical production raw materials. Understanding their properties and uses is of great significance for improving chemical production efficiency and product quality.
