Separation of dienic, naphthenic, and aromatic hydrocarbons from cuts containing them, using cyanamide solvents

Separation of dienic, naphthenic, and aromatic hydrocarbons from cuts containing them, using cyanamide solvents. 71-43-2 are also occured in this study. Atlani, Martial; Corso, Vincent; Wakselman, Claude (Compagnie Francaise de Raffinage S. A.; Agence Nationale de Valorisation de la Recherche, Fr.). Fr. Demande FR 2335584 15 Jul 1977, 21 pp. (French). (France). CODEN: FRXXBL. CLASS: IC: C10G021-20. APPLICATION: FR 75-39059 19 Dec 1975. DOCUMENT TYPE: Patent CA Section: 51 (Fossil Fuels, Derivatives, and Related Products) Section cross-reference(s): 48 The title hydrocarbons are sepd. by liq.-liq. extn. or extractive distn. by using substituted cyanamides as solvents. The solvent is exemplified by RR1NCN (R and R1 = alkyl or alkenyl) or N-cyanoheterocyclic compds. Thus, C6H6 [71-43-2] and n-heptane [142-82-5] were sepd. in the presence of N-cyanomorpholine [1530-89-8] solvent. A mixt. was prepd. that contained 17.5, 32.5 and 50.0 wt.%, resp., of the 3 compds. The ext. contained 15.5, 2.5, and 82, and the raffinate 21, 73, and 6 wt.%, resp., of the 3 compds. .

An unknown salivary morpholine metabolite

An unknown salivary morpholine metabolite. Wishnok, John S.; Tannenbaum, Steven R. (Dep. Nutr. Food Sci., Massachusetts Inst. Technol., Cambridge, Mass., USA). Anal. Chem., 49(8), 715A-716A, 718A (English) 1977. CODEN: ANCHAM. DOCUMENT TYPE: Journal CA Section: 4 (Toxicology) Section cross-reference(s): 80 In a expt. to study the formation of possible carcinogenic nitrosamines, morpholine [110-91-8] was treated with human saliva, and N-nitrosomorpholine [59-89-2] and an unknown morpholine deriv. was detected in the morpholine-treated saliva. The unknown metabolite was identified by mass spectroscopy and by comparison with a synthetic sample to be N-cyanomorpholine (I) [1530-89-8]. I was found to be nonmutagenic.
