What is Acrylic Acid?

Acrylic Acid is the easiest unsaturated carboxylic acid with a molecular framework consisting of a vinyl group and a carboxyl group. Pure acrylic acid is a clear, colorless fluid with a characteristic poignant smell. Thickness 1.0511. Melting point 14 ℃. Boiling point 140.9 ℃. Strong acidity. Corrosive. Soluble in water, ethanol and also ether. Chemically energetic. Easy to accumulation right into clear white powder. Propionic acid is created during decrease. When included with hydrochloric acid, 2-chloropropionic acid is formed. For the preparation of acrylic resin, etc, but additionally for various other natural synthesis. It is obtained by the oxidation of acrolein or the hydrolysis of acrylonitrile. It can likewise be synthesized from acetylene, carbon monoxide as well as water, or obtained by the stress oxidation of ethylene and also carbon monoxide.
Acrylic acid can undertake the characteristic response of carboxylic acid, and also the equivalent ester can also be obtained by response with alcohol. One of the most typical acrylates consist of methyl acrylate, butyl acrylate, ethyl acrylate, and also 2-ethylhexyl acrylate.

Preparation method of Polymer Acid

The original powder of silicate zeolite MCM-49 synthesized by hydrothermal crystallization was exchanged with 1 mol/L ammonium nitrate solution at 85 °C for 6 h, filtered and washed with suction, repeated 3 times. The obtained filter cake was dried at 120 °C and calcined at 540 °C for 3 h to obtain H-MCM-49 zeolite.

Dissolve 123.5 grams of ammonium paramolybdate and 14.9 grams of ammonium metavanadate in 500 grams of distilled water to obtain solution A. Solution B was obtained by dissolving 28.2 g of copper nitrate and 31.8 g of strontium nitrate in 100 g of distilled water. The solution B was firstly added to the solution A under stirring, and the pH of the mixed solution was adjusted to 6 with ammonia water, and the temperature was raised to 70°C for aging for 5 hours. After being evaporated to dryness at 100°C, dried at 120°C, and pre-calcined at 250°C for 3 hours and 400°C for 6 hours in an air atmosphere, the composite oxide catalyst Mo12V2.2Cu2Sr1.5OX for the oxidation of acrolein to acrylic acid was prepared .

Put 5ml of 10-20 mesh H-MCM-49 type zeolite catalyst into a stainless steel reactor (the first reactor) with an outer diameter of 12 mm and an inner diameter of 8 mm, and put 15 ml of 10-20 mesh Mo12V2.2Cu2Sr1.5OX catalyst into the outer A stainless steel reactor (second reactor) with a diameter of 19 mm and an inner diameter of 15 mm was connected in series. Glycerol, water and nitrogen are vaporized and mixed in a molar ratio of 1:0.78:8.22 and then enter the first reactor. The total gas space velocity is 3000h-1 and the reaction temperature is 360℃; the outlet of the first reactor contains acrolein. The mixed gas and the supplemented air entered the second reactor according to the volume ratio of vaporized glycerol and air being 1:7, and the reaction temperature was 270°C. The reaction product of the second reactor was sprayed and absorbed with 4°C chilled water, and then analyzed by gas chromatography. The results were: 100% glycerol conversion, 73.2% acrylic acid yield, and 20.2% carbon oxide yield after 10 hours of reaction; 100% glycerol conversion, 73.0% acrylic acid yield, and 20.5% carbon oxide yield after 400 hours of reaction.

Polymer Acid Coatings

Polymer Acid coatings mainly include thermoplastic acrylic coatings, thermosetting acrylic coatings, high solid acrylic coatings, acrylic latex paints, and water-dilutable acrylic resin coatings.
(1) The main component of thermoplastic acrylic coating is polymethyl methacrylate, but pure polymethyl methacrylate is too brittle, and has poor adhesion to the substrate, and the solvent is not easy to use up, because its glass transition temperature high. The solid content of solvent-based thermoplastic Polymer Acid coatings is too low (volume concentration is about 12%), and the amount dropped sharply after entering the 1970s. Instead, thermosetting acrylic coatings were developed, especially high-solid acrylic acid. coating.
(2) Thermosetting acrylic resin can increase the non-volatile content of the coating, and crosslinking occurs during the curing process after the coating is applied. In addition to higher solid content, thermosetting acrylic coatings have better gloss and appearance, better chemical resistance, solvent resistance, alkali resistance, heat resistance, etc. The disadvantage is that they cannot be stored for a long time. Thermosetting acrylic coatings use melamine-formaldehyde resins or polyisocyanates as crosslinking agents.
(3) It is difficult to prepare Polymer Acid resins for high solids coatings. Generally, the volume solid content of high-solid polyester coatings can reach 65% to 70%. It is easy for polyester to ensure that there are more than two hydroxyl groups on each molecule, but it is difficult for acrylic resin to achieve more than two hydroxyl groups on each molecule. hydroxyl. In order to solve this problem, one is to increase the amount of hydroxyethyl methacrylate (HEMA), such as increasing it to 15%; the other is to make the molecular weight distribution of the resin as narrow as possible, and the distribution of polar groups should be as uniform as possible. The latter is very critical in high solids coatings. At present, the volume solid content of high solid acrylic resin coatings can reach 54% to 56% (weight solid content can reach 70% to 72%) under the spray viscosity.
(4) Acrylate latex is the best and most important latex. Compared with polyvinyl acetate emulsions, Polymer Acid emulsions improve the flexibility and adhesion of coatings, and the cost is moderate. In addition, its outdoor durability, including resistance to UV light degradation, is significantly improved, leading to applications in architectural coatings for walls, floor polishes that can be scrubbed and decontaminated, and paint printing pastes.
(5) Water-dilution Polymer Acid resin is a thermosetting resin. First, a water-soluble polymer is prepared, which will be cross-linked into a water-resistant and tough coating during film formation. Water-thinned acrylic paints can be used for spray painting, dip painting, etc. The most successful application is can lining coatings. Another important application is electrophoretic paint.
