Application of pesticides
So, for the synthesis of acetate or acetone pinacolone can be synthesized in a variety of new pesticides, fungicides , plant growth regulators and pesticides , such as triazole alcohol, benzyl chloride triadimenol , triadimefon ( triadimefon ) , MET double oxacillin alcohol , effects azole , allyl trazodone , tebuconazole , sprout inhibition azole , shrink strains azole Fortunately, trazodone and so on. These products have high efficiency , low toxicity , uptake , broad-spectrum , with less Vinca and other characteristics of rice, wheat , soybeans , fruit, vegetables and other crops with resistance to plant diseases and insect pests , such as lodging has good control effect .
Application of medicine
Pivaloyl chloride production furosemide ampicillin , double-effect material pivaloyl adrenal table can be used for the production of ampicillin , amoxicillin , cefazolin , and other semi-synthetic antibiotics. Pivalate prepared with prednisone good solubility , high efficacy , side effects, can be used to treat rheumatoid arthritis. Benzoyl pivalate capillaries increase the stability , for the treatment of tuberculosis. Pivalate prepared fluorometholone , used as an ointment for treating psoriasis of the active ingredient .
Application areas initiator agent
Pivalic acid chloride is reacted with t-butyl peroxide , sodium peroxide, t -butyl ester generated can produce free radicals , may be as low temperature -50 ℃, high efficiency , short induction period, the short cycle characteristics. In addition, use it as efficient initiator, polymers produced good thermal stability, good electrical properties , non-toxic , with a large and good linearity , etc. in the structure of the molecular weight of the product can be used as food packaging bags.
By Nippon Oil & Fats Co., Ltd. A novel pivalate peroxide initiator , t-hexyl peroxide Kit pivaloyl (HPP), which is the initiator efficiency , has no toxicity , low activity and other characteristics. And by its high peroxide initiator di – compound ( 2 -ethyl) hexyl acrylate with an initiator system consisting of a suspension of PVC in the production of a number of advantages : to reduce the polymerization time , the reaction heat uniformly to facilitate the process operation ; product particle morphology is good, “fish eyes” small, narrow molecular weight distribution, good quality products.
Pivalate for synthesis triggered there is great potential agents , should increase research efforts.
Application of coatings
Pivalic acid obtained by the initiator produced polyacrylate coating agent as compared with the conventional initiators obtained by selecting the specific structure of such an initiator and a chain transfer agent, a high solids synthetic hinge polyacrylate paint showed a higher gloss and gloss retention in aging experiments.
Shell Oil Company can be reported pivalic preparing epoxy powder coating treatment agent. Such a treatment agent with the powder coating with excellent color and luster and easy hydrolysis durable.
Other Applications
Pivalate having a resistance to hydrolysis and aroma , fragrance soap used as shampoos . Such as n-propyl pivalate with fruit, especially n-amyl valerate with orchid flavor, especially valerate with citrus flavor. Allyl pivalate can be used in the manufacture of hair gel . Pivalic acid esters of polyethylene glycol used as a truck ‘s brake oil, its lithium salt used as an engine fuel additive to increase the octane number . With a special acid as photosensitive materials coupler, with consumption of a small amount of silver , which will help thinning the layer to improve film clarity, the coupling reaction speed and other characteristics. In addition , special acid extraction agent also used metal , wood preservatives , etc., is widely used.
