Sulfuric acid was added to an autoclave, and the air in the autoclave was replaced three times with carbon monoxide. Then, carbon monoxide was added to bring the pressure to approximately 4.90 MPa. The autoclave was stirred, and a small amount of chloroform was added first using a metering pump, followed by a 1:1 volume ratio of isobutylene to chloroform, which was added over approximately 3 hours. The pressure inside the autoclave was maintained at approximately 4.90 MPa throughout the process. After adding the reaction mixture, the mixture was stirred at room temperature for 30 minutes, and then discharged. The reacted material was stirred in ice water for 15 minutes. The chloroform layer was separated and dried with anhydrous sodium sulfate. The mixture was distilled, and the fraction collected at 65–70 °C (2.67 kPa) yielded trimethylacetic acid with a purity of 97% and a yield of 74%. This trimethylacetic acid was then reacted with KOH to produce PotassiuM triMethylacetate. |

PotassiuM triMethylacetate, 95% (KP) is a reactive monocarboxylic acid that can be synthesized from the reaction of diethanolamine with potassium halides. KP has been shown to react with amines and form urea derivatives, which can be used for cross-coupling reactions. These reactions are catalyzed by palladium-based catalysts. KP is also used as an intermediate in the production of trimerization reagents, such as triethylamine and tripropylamine, which are used in fabricating polyurethane foam. Potassium pivalate is also an effective dose for the synthesis of pyrazole rings from carboxylates. This process involves a trimerization reaction between three molecules of KP, followed by elimination of water and decarboxylation to produce pyrazole ring. Gel permeation chromatography is often applied to purify this product. | [Uses]
Potassium trimethylacetate is used as a intermediate for chemical research. |
