Photosensitized cis-trans isomerization of Jojoba wax

Photosensitized cis-trans isomerization of Jojoba wax. Galun, Arjeh B.; Shaubi, Eleonora; Markus, Arie; Grinberg, Sarina; Zabicky, Jacob (Appl. Res. Inst., Ben-Gurion Univ., Beer Sheva 84110, Israel). JAOCS, J. Am. Oil Chem. Soc., 61(1), 102-3 (English) 1984. CODEN: JJASDH. DOCUMENT TYPE: Journal CA Section: 62 (Essential Oils and Cosmetics) Section cross-reference(s): 22 Jojoba wax solns. were irradiated at wavelengths >366 nm, in the presence of sensitizers (benzophenone [119-61-9], 2-chlorobenzaldehyde [89-98-5], benzaldehyde [100-52-7], or acetophenone [98-86-2]), at room temp. Cis-trans Isomerization took place only with sensitizers with triplet energy >68 kcal/mol. 100-52-7 and 119-61-9 are just another two chemicals used in this study. Quantum yields were low and a conversion of up to 25% of the trans isomer was achieved at the photostationary state. .

CODEN: JKXXAF. CLASS: IC: A01N009-28. APPLICATION: JP 75-6757 13 Jan 1975. DOCUMENT TYPE: Patent CA Section: 5 (Agrochemicals) Section cross-reference(s): 42, 43, 27 .alpha.-(O-chlorobenzylidene)-.gamma.-valerolactone (I) [57786-75-1] and other valerolactone ad butyrolactone derivs. are used as fungicides. The min. inhibitory concn. of I for Aspergillus niger and Rhizopus nigricans was 200 and 100 ppm, resp.There are some commonly used reagents with their cas registry numbers 57786-72-8 and 57786-80-8 in this article. These fungicides are used for fungal control in industrial goods such as paint and pulp. I was prepd. by treating .gamma.-valerolactone [108-29-2] with o-chlorobenzaldehyde [89-98-5]. .
