[ 1 ] - One-pot Multi-step Synthesis of some Aromatic Salicylaldoximes Using MgO Nanoparticles
MgO nanopartticels (NP-MgO) in average size between 30—130 nm were prepared by sonochemistry method. Some phenols have been converted to ortho-hydroxybezaldehyd by ortho-formylation using MgO nanoparticles and (CH2O)n in xylene and subsequently treated with aqueous NH2OH.HCl, affording the corresponding aldoxime in a one-pot procedure. Moreover, this one-pot process, with two transformations, o...
[ 2 ] - Rapid and Green Synthesis of some Benzothiazole-, Benzimidazole- and Benzoxazole-2-thiol Derivatives Using Copper Sulfate in Aqueous Media
In this study an easy, green, efficient and simple approach is reported for the synthesis of some benzothiazole-, benzimidazole- and benzoxazole-2-thiolderivatives. The proposed approach employs the reaction of corresponding aromatic amine with potassium isopropyl xanthate (Z11) in the presence of copper sulfate (CuSO4) as a catalyst under conventional heating and ultrasonic irr...
[ 3 ] - بهینه سازی فرایند تخریب الکتروشیمیایی رنگ اسید بلو 25 با استفاده از طراحی مرکب مرکزی و تابع مطلوبیت
ررنگ زدایی سریع الکتروشیمیایی از محلول حاوی رنگ اسید بلو 25 با استفاده از یکسو کننده جریان صورت گرفت. یک طراحی مرکب مرکزی با چهار فاکتور برای بررسی فاکتورها و برهمکنش آنها مورد استفاده قرار گرفت. پارامترهای موثر بر تخریب رنگ به نحوی بهینه شدند که بالاترین بازده تخریب رنگ با حداقل مصرف انرژی الکتریکی صورت گیرد. به این منظور از تابع مطلوبیت برای بهینه سازی پارامترها و دستیابی همزمان به هر دو هدف ...
[ 4 ] - Methane oxy-steam reforming over a highly efficient Ni/Al2O3 nanocatalyst prepared by microwave-assisted impregnation method
An alumina-supported nickel catalyst was prepared by impregnation of Ni2+ solution onto mesoporous alumina under microwave irradiation (denoted as M-Ni/Al2O3). For comparison, a catalyst with the same nickel content was prepared by conventional impregnation method (denoted as UM-Ni/Al2O3). Both M-Ni/Al2O3 and UM-Ni/Al2O3 catalysts were applied to the syngas (H2 + CO) production by methane oxy-s...
