Category : Others
CAS NO : 75-98-9 EC NO : 200-922-5 MF : C5H10O2 MW : 101.1243 Specification : 99% min Packing : 25kg 50kg drum or bag Product description : What is the chemical of Pivalic acid ? Appearance: White crystalline solid； Assay: 99% by HPLC； IR Identity: conform to standard； HNMR： conform to standard； carbon spectrum: conform to standard Water by K. F.:0.5% max or as per the customer’s request； Loss on drying:0.5% max. or as per the customer’s request； =============================================================================== It is a very important chemical raw material and reagent, as well as an important raw material and intermediate in organic synthesis. At room temperature, it is a white needle-like crystal, which can be used as a stabilizer for polyvinyl chloride and paints, and a radical promoter. It is used as an intermediate for pesticides, pharmaceuticals, and dyes, and also in high-grade coatings, polymer initiators, photosensitive materials, fragrances, lubricating oils, etc. It is an intermediate for producing carbamate insecticide zoaparathion and herbicide imazosulfuron. It can be used as a component and primary raw material for fragrances, liquid adhesives, lubricants, and humidifiers. It can also be used as a pharmaceutical raw material for treating arthritis, tuberculosis, and psoriasis, and is the raw material for trimethylacetyl chloride, a key raw material for producing ampicillin and cephalothin antibiotics. It is mainly used in the pharmaceutical, pesticide, dye intermediate, and chemical industries. In the pharmaceutical industry, it serves as an intermediate for carbamate insecticides (such as zoaparathion) and herbicides (such as imazosulfuron). It is a precursor to trimethylacetyl chloride, a key raw material for producing antibiotics (such as ampicillin and cephalothin). It is used in the synthesis of drugs for treating arthritis, tuberculosis, etc. In the chemical and materials field, it is used in high-grade coatings, polymer initiators (such as t-butyl peroxide), photosensitive materials, fragrances, lubricating oils, etc., as well as as a polyvinyl chloride stabilizer and radical promoter. In other applications, it is used as a fragrance component and a raw material for liquid adhesives. ============================================================================= Synthesis Route (Industrial Mainstream): (1) Isobutylene Carbonylation (Koch Method): (CH₃)₂C=CH₂ + CO + H₂O → (CH₃)₃CCOOH (strong acid catalysis, such as H₂SO₄/HF, high pressure); (2) Condensation of Isobutanol with Formic Acid: (CH₃)₂CHCH₂OH + HCOOH → (CH₃)₃CCOOH + H₂O (concentrated H₂SO₄ catalysis, heating); (3) Hydrolysis after Cyanide Cleavage of tert-Butyl Halide: (CH₃)₃CCl → (CH₃)₃CCN → (CH₃)₃CCOOH (acidic hydrolysis, lower yield due to steric hindrance). This substance is a corrosive chemical (for reference only). Uses : It is a very important chemical raw material and reagent, as well as an important raw material and intermediate in organic synthesis. At room temperature, it is a white needle-like crystal, which can be used as a stabilizer for polyvinyl chloride and pain Synonyms : 2,2-Dimethylpropanoic acid;Pivalic acid;2,2-dimethylpropanoate; Molecular Structure :
