Application Of Pivalic Acid In Coating

Shandong Minji Chemical Co.,Ltd | Updated: Aug 31, 2017



Special valeric acid, also known as trimethylacetic acid or 2,2-dimethyl propionic acid, also known as pivalic acid, is an important chemical raw materials. Because of its carbonyl group can be connected to the tertiary carbon atoms, it shows some special physical and chemical properties, Pivalic Acid in the organic synthesis industry has been widely used. In recent years, a variety of new pharmaceuticals, pesticides, coatings and other intermediates are special valeric acid as the starting material, these intermediates show a very bright future, domestic and international market consensus, many intermediates have become hot development products, Downstream market huge development space to stimulate and promote the production and development of pivalic acid.

Aspartic acid because of its structure of the particularity, Pivalic Acid in the synthesis of fine chemical products has a wide range of applications. Widely used in pesticides, pharmaceuticals, initiators, coatings and many other areas.

3.1 Application of pesticides

The synthesis of a variety of new pesticide fungicides, plant growth regulators and insecticides, such as triadimenol, benzyl chlorotriazole alcohol, triazolone, ), Paclobutrazol, dibenzoylenol, idiopheneazole, ketazolone, tebuconazole, oligosilazole, squad, azazolone and the like. Pivalic Acid These products have the characteristics of high efficiency, low toxicity, internal absorption, broad spectrum, low dosage and long residual effect. They have good control effect on the pests and diseases such as rice, wheat, soybean, fruit trees and vegetables.

3.2 The application of medicine

Pivaloyl chloride is the production of furosemide, double effect of the adrenal gland table of raw materials, can also be used to produce ampicillin, amoxycillin, cefazolin and other semi-synthetic antibiotics. Delethoate prepared by the solution of prednisone good solubility, high efficacy, side effects, Pivalic Acid can be used for the treatment of rheumatoid arthritis. Benzylpentate can increase the stability of capillaries and can be used to treat tuberculosis. Pivalic Acid Fentanic acid prepared by pivalic acid can be used as an active ingredient in the treatment of psoriasis ointment.

3.3 Initiator aspects of the application

Tert-butyl peroxide produced by the reaction of the acid chloride and tert-butyl peroxide to produce free radicals, the use of temperature can be as low as -50 ℃, with high efficiency, short induction period, short cycle and so on. In addition, it is used as a highly efficient initiator, Pivalic Acid the production of polymer thermal stability, good electrical properties, non-toxic, in the structure of the product with a large molecular weight and good linearity, etc., can be used as food packaging bags.

Nippon Oil & Fats Co., Ltd. has synthesized a new peroxide initiator, such as tert-hexyl pivaloyl peroxide (HPP), which is a medium-acting initiator with non-toxic and low-temperature activity. The composite initiator system consisting of it and the efficient initiator, bis (2-ethylhexyl) peroxydicarbonate, Pivalic Acid has many advantages in the production of PVC suspension: it can shorten the polymerization time, the reaction is exothermic and the process is easy to operate. Particle shape is good, "fish eyes" less, narrow molecular weight distribution range, product quality is good.

Especially valeric acid for the synthesis of the initiator there is a great potential, should increase the intensity of research.

3.4 Application of paint

The polyacrylic acid ester coating produced from the initiator made from pivalic acid is obtained by selecting a special structure of the initiator and the chain transfer agent as compared with the conventional initiator, Pivalic Acid and the synthetic high solid content polyacrylate hinge Paint in the aging test showed a higher gloss and light retention performance.

Pivalic acid can also be used to prepare epoxy resin powder coating agent. Pivalic Acid The powder coating treated with this treatment agent has excellent color and gloss and is difficult to hydrolyze and durable.

3.5 Some other applications

Extra valerate has a resistance to hydrolysis and a certain aromatic odor, can be used as a fragrance of shampoo soap. Such as n-propyl pivalate has a fruit flavor, Pivalic Acid n-amyl valerate has a orchid flavor, methyl pivalate with citrus flavor. Allyl valerate can be used to make hair gel. Polyethylene glycol monoester of pivalic acid can be used as a brake oil for trucks, Pivalic Acid and its lithium salt is used as an engine fuel additive to increase the octane number. With special valeric acid as a photosensitive material of the coupler, with a small amount of silver consumption, which will help thinning the layer, improve film clarity, coupling reaction speed and so on. In addition, the special valerate can also be used as a metal extractant, wood preservatives, etc., is widely used.
