In 2022,Osafune, Yukio; Toshida, Kenji; Han, Jinshun; Kishimoto, Toru; Iizuka-Furukawa, Sachiko; Isogai, Atsuko; Mukai, Nobuhiko published an article in Journal of Bioscience and Bioengineering. The title of the article was 《Identification of 2-furanmethanethiol contributing to roast aroma in honkaku shochu and awamori》.Reference of Ethyl propiolate The author mentioned the following in the article:
Honkaku shochu and awamori are traditional Japanese spirits. 2-Furanmethanethiol (2FM), a volatile thiol, was identified as a roast aroma compound in honkaku shochu and awamori. The detection threshold of 2FM in 25% (volume/volume) ethanol water solutions was determined as 1.6 ng/L. The odor activity values, calculated using the detection threshold suggested that 2FM affects the quality of honkaku shochu and awamori. The odor activity values of 2FM were higher in barley shochu distilled at atm. pressure than in sweet potato shochu, rice shochu and awamori; therefore, 2FM is considered to contribute to the characteristics of barley shochu. The experimental part of the paper was very detailed, including the reaction process of Ethyl propiolate(cas: 623-47-2Reference of Ethyl propiolate)
Ethyl propiolate(cas: 623-47-2) is a clear colorless to pale yellow liquid that is soluble in ethanol, ether and chloroform. It an important organic chemical raw material and pharmaceutical intermediate. Ethyl propargylate is obtained by oxidation of propargyl alcohol to propargylic acid followed by esterification.Reference of Ethyl propiolate
