2-Isopropyl-N,2,3-trimethylbutyramide Chemical Properties,Usage,Production
Description
2-isopropyl-N,2,3-trimethylbutyramide is one nearly odorless white crystalline powder widely used as a coolant in medicinal preparations, oral care products, foodstuffs, cosmetics, and confection-eye products. It is an artificial synthesis cooling agent and could be synthesized by the Ritter reaction of 2,2-diisopropylpropionitrile (DIPPN) with methanol in the presence of acid. Compared with menthol, WS-23 is characterized by a continuous and long-lasting cooling and refreshing effect with no side effects of burning or stinging sensations. As an important additive in menthol cigarettes, WS-23 can cover up the bitter and astringent taste of cigarettes, make the cigarette feel fresh, improve the coordination and softness of cigarette smoke, and reduce the thorn in the mouth and throat. WS-23 is also compatible with other flavors and cooling agents[1].
Chemical Properties
N,2,3-Trimethyl-2-isopropylbutanamide is a white, crystalline powder,which gives a physiological
cooling sensation on skin or mucosa. It is mainly used to create cooling
and freshness in oral care preparations.
The material can be prepared by a Ritter reaction using N,2,3-trimethyl-2-
isopropylbutyronitrile as the starting material and alkylating agents such as, for
example, borates, carbonates, or phosphates.
Chemical Properties
2-Isopropyl-N-2,3-trimethylbutyramide has a cool, mint–menthol-type odor
Uses
2-Isopropyl-N,2,3-trimethylbutanamide is flavored compound and comprising the recount flavored compound for electronic cigarette liquid.
Uses
Physiological coolant in foods, beverages, tobacco products, toiletries, cosmetics and pharmaceuticals.
Definition
ChEBI: N,2,3-Trimethyl-2-(1-methylethyl)butanamide is a fatty amide.
Aroma threshold values
Aroma characteristics at 5.0%: slight cooling impact with little character.
Taste threshold values
Taste characteristics at 20 ppm: high-impacting cooling that lasts on the tongue and palate.
Trade name
Winsense WS-23 (Renessenz).
Synthesis
67029-99-6
51115-67-4
Step 3: 3-isopropyl-4-methyl-2-pentanone (128 g, 0.82 mol) obtained above was dissolved in tetrahydrofuran, followed by the addition of hydroxylamine hydrochloride (1.2 equiv.) and potassium carbonate and the reaction was stirred. The progress of the reaction was monitored by TLC and after confirming that the reaction was complete, water was added to the reaction mixture and extracted with ethyl acetate. The organic phases were combined, dried over anhydrous sodium sulfate and concentrated under reduced pressure to give 135 g of crude product. The crude product was dissolved in polyphosphonic acid and heated to 100 °C for 3-8 hours. After the reaction was completed, the reaction solution was neutralized with alkali, extracted again with ethyl acetate, and the organic phase was dried over anhydrous sodium sulfate and then distilled under reduced pressure to remove the solvent. Finally, it was purified by recrystallization to obtain N,2,3-trimethyl-2-isopropylbutyramide 85 g with 99% purity and 49.7% combined yield.
