Numerous contributions have been made to our knowledge of the process of conjugation of phenol in vivo (2, 3). The studies in vitro are related to the formation of either phenyl sulfate (4-6) or glucuronide (7-11). Because of the great difference in behavior towards hydrolysis of the sulfate and the glucuronide (12), the formation of phenyl sulfate and phenyl glucuronide can be followed simulta...

background: omega-3 fatty acids have established beneficial effects for cardiovascular disease. the use of omega-3 supplements for patients with non-alcoholic fatty liver disease (nafld) was proposed. the purpose of this study was to review the relationship between omega-3 fatty acids intake and nafld. methods: in this study, the terms such as nafld, omega-3 fatty acids, docosahexanoic acid, an...

The expense of repair and maintenance of private and public sewage systems in Germany runs to about 100 billion US $. This primarily affects concrete pipes and brickwork sewers. Approximately 40 per cent of the damage can be attributed to corrosion by biogenous sulfuric acid attack as a result of long flow periods and insufficient ventilation of waste water. The report deals with investigations...

ABSTRACT. The effect of acetic acid and ethanol as polar aqueous solvents on sulfuric with hydrogen peroxide an oxidant was studied. A small amount these significantly improved the copper leaching recovery. parameters such temperature, stirring speed, H2O2 concentration, solid/liquid ratio, H2SO4 concentration particle size were examined. About 76.33% highest Cu extraction gained 2 M H2O2, 600 ...

The reaction of 3-chloropropyl boehmite nanoparticles with caffeine and sulfuric acid afforded BNPs-3-propyl-imidazolopyridinium hydrogen sulfate [BNPs-Caff]HSO4 as a new BNPs-supported ionic liquid (IL) catalyst. [BNPs-Caff]HSO4 proved to be an efficient heterogeneous catalyst for the synthesis of pyrazolopyranopyrimidines via a one-pot four-component reaction of...

nano silica sulfuric acid as a solid acid, was described to be an effective catalyst for one-pot three-component reaction of kojic acid, aryl aldehydes and indoles for the preparation of 2-substituted aryl (indolyl) kojic acid derivatives. the catalyst was prepared by combination of chlorosulfonic acid to nano silica gel. the size of nanoparticles were observed with sem.all prepared compounds w...
