Effects of methyl linoleate hydroperoxide and hydrogen peroxide on N-nitrosation of dimethylamine

Effects of methyl linoleate hydroperoxide and hydrogen peroxide on N-nitrosation of dimethylamine. Kikugawa, K.; Kato, T.; Konoe, Y.; Sawamura, A. (Tokyo Coll. Pharm., Tokyo 192-03, Japan). Food Chem. Toxicol., 23(3), 339-42 (English) 1985. CODEN: FCTOD7. ISSN: 0278-6915. DOCUMENT TYPE: Journal CA Section: 4 (Toxicology) The effects of Me linoleate hydroperoxide (I) [11068-03-4] and H2O2 on the N-nitrosation of dimethylamine [124-40-3] were investigated. H2O2 inhibited the formation of N-nitrosodimethylamine [62-75-9] by the reaction of dimethylamine and nitrite in citrate buffer (pH 3-5). The inhibitory effect was due to the loss of available nitrite by quant. conversion into nitrate. The formation of N-nitrosodimethylamine from the reaction of dimethylamine and nitrous acid in CHCl3 was effectively inhibited by I. The inhibitory effect of I was much greater than that of Me linoleate [112-63-0]. The loss of nitrous acid from the reaction mixt. was due to the conversion of nitrous acid into nitric acid and the formation of 2 adducts, both of which contained N and had peroxide and carbonyl or carbonyl-liberating functions. Evidently, unsatd. fatty acids and lipid hydroperoxides are effective inhibitors of nitrosamine formation.

Catalytic isomerization of safflower oil with rhodium complexes

Catalytic isomerization of safflower oil with rhodium complexes. Basu, Amitabha; Kasar, T. G. (Alchemie Res. Cent., Thane 400 601, India).Some commonly used reagents like 78360-52-8 and 47859-60-9 are used in this experiment. JAOCS, J. Am. Oil Chem. Soc., 63(11), 1444-7 (English) 1986. CODEN: JJASDH. DOCUMENT TYPE: Journal CA Section: 45 (Industrial Organic Chemicals, Leather, Fats, and Waxes) Complexes of the type [(NBD)RhL2]+ ClO4- (NBD = norbornadiene; L = Ph3P or diphenylphosphinoethane) were studied as catalysts for the isomerization of Me linoleate (I) [112-63-0] and safflower oil. The catalysts gave very good yields of conjugated products with both oil and I. The isomerization could be carried out under very mild conditions (55-65°, 1 atm N2). Although the catalyst underwent transformation in the course of the reaction, it maintained its catalytic activity. In fact, the catalysts isolated from the reaction with safflower oil were recycled with practically no loss of activity. .
