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. | [Chemical Properties]
Potassium valerate is a white powder that is readily soluble in ethanol and diethyl ether and is also soluble in water. It is slightly acidic and corrosive and can corrode metals. | [Uses]
Potassium trimethylacetate is used as a intermediate for chemical research. | [Preparation]
Sulfuric acid was added to an autoclave, and the air inside was purged with carbon monoxide three times. Carbon monoxide was then introduced until the pressure reached approximately 4.90 MPa. With the autoclave stirring, a small amount of chloroform was initially added using a metering pump, followed by the addition of isobutylene and chloroform in a 1:1 volume ratio over approximately 3 hours. The pressure inside the autoclave was maintained at approximately 4.90 MPa throughout the process. After the addition was complete, the reaction mixture was stirred at room temperature for 30 minutes and then discharged. The discharged material was stirred in ice water for 15 minutes. The chloroform layer was separated and dried over anhydrous sodium sulfate. The resulting mixture was distilled, and the fraction collected at 65–70 °C under a pressure of 2.67 kPa yielded trimethylacetic acid with a purity of 97% and a yield of 74%. The resulting trimethylacetic acid was then reacted with KOH to produce potassium trimethylacetate. |
