Uses and synthesis of Methacrylic acid Liquid

Methacrylic acid Liquid is colorless crystal or transparent liquid with irritating odor. Soluble in hot water, soluble in most organic solvents such as ethanol, ether, etc. Methacrylic acid CAS 79-41-4 is easy to polymerize into water-soluble polymers. Flammable, with high heat, open flame has the danger of combustion, thermal decomposition can produce toxic gases.

Methacrylic acid Liquid is an important chemical raw material, Methacrylic acid CAS 79-41-4 has two functional groups of carbon-carbon double bond and carboxylic acid group, so it can be polymerized and esterified, etc. Methacrylic acid Raw Materials can be used in the preparation of methyl methacrylate, paint, Methacrylic acid Raw Materials can be used in the preparation of methyl methacrylate, coatings, synthetic rubbers, adhesives, fabric treatments, resins, polymer additives and functional polymer materials.

Applications / Functions of Methacrylic Acid Liquid

1. Methacrylic acid CAS 79-41-4 is used in the manufacture of coatings, insulating materials, adhesives and ion exchange resins.
2. Important organic chemical materials and polymer intermediates.Methacrylic acid Raw Materials the most important derivatives of methyl methacrylate production of plexiglass can be used in aircraft and civil construction of the window, but also can be processed into buttons, solar filters and automotive lamps lens, etc.; production of coatings with superior suspension, rheology and durability; made of adhesives can be used in metals, leather, plastics and building materials. It can be used for the bonding of metal, leather, plastic and construction materials; Methacrylate polymer emulsion is used as fabric finishing agent and antistatic agent.
3. In addition, Methacrylic Acid Liquid is used as a raw material for synthetic rubber.
4. Methacrylic Acid Raw Materials are used as organic reagents.
5. Manufacture of resins and plastics, polymers, manufacture of esters.

Physicochemical Property of Methacrylic acid Liquid

Colorless and transparent liquid at room temperature. Methacrylic acid Raw Materials is soluble in hot water, ethanol and most organic solvents.

production methodprocess of Methacrylic acid Liquid

There are two main industrial production methods of Methacrylic acid Raw Materials, namely, acetone cyanohydrin method and isobutene (tert-butanol) oxidation method.

• 1.Acetone cyanohydrin method Acetone and hydrocyanic acid in the presence of alkali catalyst, the reaction to generate acetone cyanohydrin, and then reacted with concentrated sulfuric acid to generate methacrylamide sulfate, and then hydrolyzed to generate methacrylic acid. The production of acetone cyanohydrin and sulfuric acid is required to be free of moisture, otherwise it will produce acetone or α-hydroxyisobutyric acid methyl ester left in the product, affecting product quality. To produce methacrylic acid by acetone cyanohydrin method, each ton of product consumes 898kg of sodium cyanide (>87%), 1100kg of acetone (98.5%) and 4080kg of sulfuric acid (fuming).
• 2. Isobutylene (tert-butanol) oxidation method Isobutylene is oxidized in two steps, the first step generates methacrolein, the second step generates methacrylic acid, and then qualified Methacrylic acid Liquid is obtained by distillation.
• 3.Methacrylic Acid Hydrolysis MethodTaking isobutene as raw material, Methacrylic Acid Raw Materials are obtained by ammonia oxidation and hydrolysis.
• 4.Methacrylic Acid CAS 79-41-4 is obtained by oxidizing methacrylic aldehyde by isobutane oxidation method.
