Pivalic Acid For pesticides, pharmaceuticals, dyes intermediates.

Pivalic acid, Trimethylacefic acid, is an important chemical raw materials for pesticides, pharmaceuticals, dyes intermediates, such as pivalic acid, trimethylacetic acid, 2,2-dimethyl propionic acid, , But also for high-grade coatings, polymerization initiators, photographic materials, spices, etc., Pivalic Acid is the most widely used alkyl carboxylic acid one.

Povaric acid, acetic acid or acetone as raw materials can be synthesized by a variety of new pesticide fungicides, plant growth regulators and pesticides such as triazole alcohol, benzyl chloride triazole alcohol, triazolone (pink rust Ning) , Paclobutrazol, dibenzoyl alcohol, idiopheneazole, ketazolone, tebuconazole, oligosilazole, squad, azazolone and the like. These products have the characteristics of high efficiency, low toxicity, internal absorption, broad spectrum, low dosage and long residual effect. Pivalic Acid They have good control effect on the pests and diseases such as rice, wheat, soybean, fruit trees and vegetables.

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, 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., Pivalic Acid can be used as food packaging bags.

(HPP), which is a medium-acting initiator, has the characteristics of non-toxic and low-temperature activity, which is a new peroxide initiator with pivalic acid. The composite initiator system consisting of it and the efficient initiator, bis (2-ethylhexyl) peroxydicarbonate, 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, Pivalic Acid should increase the intensity of research.

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, and the synthetic high solid content polyacrylate hinge Paint in the aging test showed a higher gloss and light retention performance.
