چکیده
A series of C(80) isoprenoid 20-bis-16,16'-biphytanyl tetraacids has previously been found to be responsible for calcium naphthenate scaling in crude oil processing. This paper describes the structure elucidation by high-field NMR spectroscopy of the structures of the series of homologous C(80) tetraacids containing 4-8 five-membered rings. In addition, the structures of methyl-substituted C(81) and C(82) analogues containing 7 and 8 five-membered rings have been determined for the first time. The biosynthetic implications are discussed.

Explanation of the different preferential binding sites for Ce and La in M 2 @ C 80 ( M 1⁄4 Ce , La ) — a density functional theory prediction
Metallofullerenes have many possible uses in technology and even in bio-medical applications. Some fullerenes have been found to have two incarcerated metal atoms such as M2@C80 (M 1⁄4 La, Ce, etc.). We have calculated the structural and electronic properties of Ce2@C80 using density functional theory (DFT). Ce is known to be preferentially incorporated into the Ih symmetric C80 isomer as La do...
متن کاملDetermination of Saturates, Aromatics, Resins and Asphaltenes (SARA) Fractions in Iran Crude oil Sample with Chromatography Methods: Study of the Geochemical Parameters
In this study, Iran crude oil samples (K, L) were separated on the basis of solubility and polarity, resulting in saturates, aromatics, resins, and asphaltenes fractions. The fractions were analyzed by traditional open column chromatography, thin layer chromatography-Flame ionization detector in an Itroscan instrument (TLC-FID) and Gas chromatography with flame ionization detection for the dete...
متن کاملApplication of the Avrami Theory for Wax Crystallisation of Synthetic Crude Oil
Wax crystallisation and deposition from offshore reservoirs have been causing serious problems such as plugged pipelines and reduced production flow rates. This issue is receiving more attention from the researchers and for commercial applications due to the shift in trend from using offshore production facilities to pipelines utilization. The aim of this study is the implementation of the Avra...
متن کاملInvestigation of Reversibility of Asphaltene Precipitation and Deposition for an Iranian Crude Oil
In this work, the precipitation and re-dissolution of asphaltenes were studied for an Iranian relatively heavy crude oil. A series of experiments were designed and carried out to quantitatively examine the reversibility of asphaltenes precipitation upon the change in the solvent concentration along with the temperature. n-Heptane was used as the precipitant, and a temperature range of 30 to...

The [4 + 2] cycloaddition of o-quinodimethanes, generated in situ from the sultine 4,5-benzo-3,6-dihydro-1,2-oxathiin 2-oxide and its derivative, to La metal-encapsulated fullerenes, La2@C80 or La@C82, afforded the novel derivatives of endohedral metallofullerenes (3a,b, 4a,b and 5b). Molecular structures of the resulting compounds were elucidated using spectroscopic methods such as MALDI-TOF m...
