Improvement of the oxidation step in 2-methyl-2-pentanoic acid production. Zheng, Youtao; Zhang, Deling; Huang, Jinfang (Shanghai Light Ind. Exp. Plant, Shanghai, Peop. Rep. China). Huaxue Shijie, 26(6), 207-8 (Chinese) 1985. CODEN: HUAKAB. ISSN: 0367-6358. DOCUMENT TYPE: Journal CA Section: 17 (Food and Feed Chemistry) 2-Methyl-2-pentenal [623-36-9] was placed in a glass oxidn. column; air was then introduced at 3 L/min for 6-7 h and the oxidn. conditions were maintained at 30-40°. Air was then replaced by N for ~1 h at 40° then the column was cooled to room temp. The reaction mixt. was extd. with NaOH soln., the NaOH ext. was acidified to pH 1, washed with H2O, and distd. at reduced pressure. Distillate contg. 2-methyl-2-pentenoic acid (I) [3142-72-1] was dissolved in hexane and cooled to -30° to form I crystals. This method is simple and inexpensive and is useful for producing I as a food flavoring compd.
