Mass spectrometric analysis of polybutyladamantane oils

Mass spectrometric analysis of polybutyladamantane oils. Hala, Slavoj; Kuras, Mecislav; Zachar, Pavel (Prague Inst. Chem. Technol., Prague, Czech.). Sb. Vys. Sk. Chem.-Technol. Praze, Technol. Paliv, D33, 305-21 (Russian) 1976. CODEN: SVCTA6. DOCUMENT TYPE: Journal CA Section: 51 (Fossil Fuels, Derivatives, and Related Products) Section cross-reference(s): 24 Based on mass spectral and chromatog. data, in alkylation with isooctane [540-84-1] in the presence of AlCl3, adamantane [281-23-2] yielded tri-, tetra-, penta-, and hexabutyladamantanes (56% 1,3,5-tributyl- [59856-61-0] and 1,3,5,7-tetrabutyladamantane [63758-81-6], in whch the iso-n-sec-butyl ratio was :15 with tert-butyl absent) and small amts. of tetrapentyl- [63757-69-7] and hexyltripentyladamantane [63757-67-5], 1,1'-biadamantyl [3732-31-8] yielded mainly polybutylbiadamantyls with asym. substitution, and diamantane [2292-79-7] yielded .apprx.50g dibutyl- (chiefly 4,9-dibutyl- [63835-96-1]), 25% monobutyl- (chiefly 4-butyl- [63835-97-2]), and 25% tributyldiamantane [63757-68-6] with small amts. of pentyl derivs. As components in lubricating oils, these adamantane derivs. resembled such alkanes as squalane in oxidative stability and naphthenes in viscosity behavior.

Diamantane and 4-methyldiamantane in Naftalan and Russian petroleums

Diamantane and 4-methyldiamantane in Naftalan and Russian petroleums. Musaev, I. A.; Bagrii, E. I.; Kurashova, E. Kh.; Zaikin, V. G.Chemicals with cas numbers 41171-94-2 and 2292-79-7 also play role.; Sanin, P. I. (Inst. Neftekhim. Sint. im. Topchieva, Moscow, USSR). Neftekhimiya, 23(5), 600-3 (Russian) 1983. CODEN: NEFTAH. ISSN: 0028-2421. DOCUMENT TYPE: Journal CA Section: 51 (Fossil Fuels, Derivatives, and Related Products) Section cross-reference(s): 24 The thermodiffusion (hot wall 120°, cold wall 10°) of fractions (b. 250-350°) from the title petroleums gave I [R = H (I) [2292-79-7] and equatorial Me (II) [28375-86-2]]. Both of these compds. were identified by their retention times in gas chromatog. and also mass spectroscopy. The compns. of I and II in the Russian oil field (Western Siberia) crude was 6 and 9 times, resp., higher than their concns. in the Naftalan crude. Besides I these crudes contained also detectable concn. of tetracyclo[6.3.1.11,6.02,3] tridecane [52353-12-5] (cyclopentanoadamantane) and tetracyclo[7.3.1.02,7.17,11]tetradecane [41171-94-2] (cyclohexanoadamantane). .
