Reductive catalytic fractionation of biomass has recently emerged as a powerful lignin extraction and depolymerization method to produce monomeric aromatic oxygenates in high yields. Here, bifunctional molybdenum-based polyoxometalates supported on titania (POM/TiO2 ) are shown to promote tandem hydrodeoxygenation (HDO) and alkylation reactions, converting lignin-derived oxygenated aromatics in...
در این بررسی خمیر ماهی کپور سرگنده با استناد بر سه فرمول تهیه و براساس آزمایش های چشایی (organoleptic properties) فرمول شماره سه انتخاب شد. سپس این محصول به سه قسمت تقسیم گردید. نمونه1 (شاهد) ،نمونه 2 (حاوی01/0 درصد آنتی اکسیدان (butylated hydroxy anisole )bha و نمونه3 (حاوی 02/0 درصد آنتی اکسیدان bha) بودند. نمونه ها منجمد و برای تعیین زمان ماندگاری در سردخانه در 18- درجه سلسیوس نگهداری شدند و...
In this project, total phenolic and flavonoid contents of the aqueous extract of Laurus nobilis L. leaves were evaluated by colorimetric methods. These natural products which are found in plants extracts, can be considered as reducing and stabilizing agents in the synthesis of metal nanoparticles. Regarding to high amounts of these compounds in the extract, silver nanoparticles were synthesized...
Binary Ni–Cu heterogeneous catalysts are known to demonstrate excellent activity in conventional hydrogenation of phenolic compounds, and Cu addition facilitates hydrodeoxygenation (HDO). In this study, we aimed show the effect on specific catalytic selectivity transfer hydrogenation, which 2-PrOH was used as a solvent an H donor. Catalytic transformations anisole were studied sub- supercritica...
