1. Product Introduction                                                                                          

(1) Acrylic acid is the simplest unsaturated carboxylic acid. Its molecular structure is composed of one vinyl group and one carboxyl group. Pure acrylic acid is a colorless clear liquid with characteristic pungent smell. Density 1.***1. Melting point: *4 ℃. Boiling point **0.9 ℃. Strong acidity. Corrosive. Soluble in water, ethanol and ether. Chemically active. Easy to polymerize into transparent white powder. Propionic acid is formed during reduction. *-chloropropionic acid is formed when it is added with hydrochloric acid. It is used for preparing acrylic resin and other organic synthesis. It is prepared by oxidation of acrolein or hydrolysis of acrylonitrile, synthesis of acetylene, carbon monoxide and water, or pressurized oxidation of ethylene and carbon monoxide.

(2) Acrylic acid can undergo the characteristic reaction of carboxylic acid, and the corresponding esters can also be obtained by reacting with alcohol. The most common acrylates include methyl acrylate, butyl acrylate, ethyl acrylate and *-ethylhexyl acrylate.

(3) After acrylic acid and its esters are mixed with itself or other monomers, polymerization will occur to form homopolymers or copolymers. Generally, monomers that can be copolymerized with acrylic acid include amides, acrylonitrile, vinyl containing monomers, styrene and butadiene. These polymers can be used to produce all kinds of plastics, coatings, adhesives, elastomers, floor polishes and coatings.

2. Usage                                                                                                                   

Acrylic acid and its series products, mainly its esters, have developed rapidly in recent years. For example, ethylene, propylene, vinyl chloride and acrylonitrile have developed into important raw materials for polymer chemical industry. Acrylic acid and its esters as monomers of polymer compounds, the world's total output has exceeded 1 million T, and the output of polymer and copolymer (mainly emulsion type resin) produced by it is nearly 5 million T. These resins are widely used in coatings, plastics, textiles, leather, papermaking, building materials, packaging materials and many other departments. Acrylic acid and its esters can be used for organic synthesis and polymer synthesis, and most of them are used for the latter, and are more copolymerized with other monomers, such as vinyl acetate, styrene and methyl methacrylate, to prepare synthetic tree esters with various properties, functional polymer materials and various additives.

3. Application                                                                                                                         

(1) Warp sizing

Warp sizing agent prepared from acrylic acid, methyl acrylate, ethyl acrylate, acrylonitrile, ammonium polyacrylate and other raw materials can desize and save starch than polyvinyl alcohol sizing agent.

(2) Adhesive

The copolymer latex of acrylic acid, methyl acrylate, ethyl acrylate and *-ethylhexyl acrylate can be used as the adhesive for electrostatic flocking and wool planting. It has good firmness and hand feel.

(3) Water thickener

A high molecular weight powder was prepared from the copolymer of acrylic acid and ethyl acrylate. It can be used as thickener in oil field. It can increase **0t crude oil per ton of product, and has good oil recovery effect for old wells.

(4) Coated paper finishing agent

Using acrylic acid, butyl acrylate, *-ethylhexyl acrylate, styrene and other quaternary copolymer latex as coated paper coating has the advantages of color retention, no yellowing, good printing performance, no roll adhesion, better than styrene butadiene latex, and can save dry pigment

(5) Polyacrylates use acrylic acid to produce various polyacrylate products (such as ammonium salt, sodium salt, potassium salt, aluminum salt, nickel salt, etc.). Used as coagulant, water treatment agent, dispersant, thickener, food preservative, acid-base resistant desiccant, softener and other polymer additives.
