Isophytol dehydration: Isophytol dehydration. Shmelev, V. A.In this study， 87984-43-8 and 505-32-8 are also used.; Sarycheva, I. K.; Evstigneeva, R. P. (Bolokhov. Khim. Komb. Sint. Poluprod. Vitam., Bolokhovo, USSR). Khim.-Farm. Zh., 17(9), 1102-6 (Russian) 1983. CODEN: KHFZAN. ISSN: 0023-1134. DOCUMENT TYPE: Journal CA Section: 30 (Terpenes and Terpenoids) Section cross-reference(s): 22 Spectral and selective hydrogenation data indicated that the dehydration of isophytol by BF3×2HOAc in BuOAc gave C13H27CH2CH:CHCMe:CHMe and C13H27CH:CHCH:CMeEt. The dehydration was a 1st order process with an activation energy of 9230 cal/mol and an activation entropy of -31.82 cal/mol °K. .
