5 /J,6/?-Epoxidation of 3 jß-Cholesteryl Acetate and its Analogues
The incorporation of oxygen containing groups into the steroid structure is of considerable interest in connection with the synthesis of corticosteroids and cardioactive substances. Oxidations with reagents containing hexavalent chromium have been widely used either to functionalize non-activated positions of policyclic hydro carbons [1 ], or to obtain through allylic oxidations keto derivativ...
متن کاملFormation of the 5,6-epoxy derivatives of 7-liydroxy-cholesteryl 3 β-acetates during peroxidation of clholesteryl acetate
La peroxidación térmica del colesteril acetato (OA) produce varios compuestos, la mayoría de los cuales fueron ya identificados en estudios precedentes. Los trimetilsilil (TMS) derivados de los productos de la termodegradación de los hidroperóxidos simples del CA (7ay 7(3-) producen espectros GC-MS que son siempre idénticos a aquellos de la peroxidación de CA, a excepción de los cuatro compuest...
متن کاملPyrolysis and catalytic pyrolysis of protein- and lipid-rich feedstock
In this study, pyrolysis of microalgal remnants was investigated for recovery of energy and nutrients. Chlorella vulgaris (C.vulgaris) biomass was first solvent-extracted for lipid recovery then the remnants were used as the feedstock for fast pyrolysis experiments using a fluidized bed reactor at 500 o C. Yields of bio-oil, biochar and gas were 53, 31, and 10wt.%, respectively. Bio-oil from C....
متن کاملMolecular products from the pyrolysis and oxidative pyrolysis of tyrosine.
The thermal degradation of tyrosine at a residence time of 0.2s was conducted in a tubular flow reactor in flowing N2 and 4% O2 in N2 for a total pyrolysis time of 3min. The fractional pyrolysis technique, in which the same sample was heated continuously at each pyrolysis temperature, was applied. Thermal decomposition of tyrosine between 350 and 550°C yielded predominantly phenolic compounds (...
متن کاملPyrolysis of Table Sugar
Table sugars were pyrolyzed at different temperatures (300, 400, and 500°C) in a fixed-bed reactor. The effect of pyrolysis temperature on yields of liquid, solid, and gaseous products was investigated. As expected the yield of liquid products gradually increased and the yield of solid products gradually decreased when the pyrolysis temperature was raised. The yield of liquid products was great...
