Fatty methylydrazides (FMHs) have been successfully synthesized from palm oil. Glycerol was produced as a by-product. The synthesis was carried out by reflux palm oil with methylhydrazine in hexane. FMHs have been characterized using elemental analysis, Fourier transform infrared spectroscopy and 1H nuclear magnetic resonance technique. The results showed that a 6:1 molar ratio of palm oil to meth...... hiện toàn bộ
One-pot synthesis, molecular docking, ADMET, and DFT studies of novel pyrazolines as promising SARS-CoV-2 main protease inhibitors

Carbon–silica composite bio-sorbents with a high density of oxygen-containing sites for efficient methylene blue adsorption
Research on Chemical Intermediates - Tập 42 - Trang 839-854 - 2015
Jia-Liang Lv, Shang-Ru Zhai, Zhen-Zhen Wang, Zhi-Min Lei, Qing-Da An
There is a growing trend to employ agricultural waste/by-products (AWBs) as substrates for the development of dye bio-sorbents, and surface modification plays a vital role in improving the sorption of dye by raw AWBs. However, the fabrication of low-cost and high-performance bio-sorbents that can effectively adsorb dye remains a great challenge. Herein, a new rice husk-based nanoporous carbon–sili...... hiện toàn bộ
‘In water’ exploration of Alpinia zerumbet-fabricated CuO NPs in the presence of NaPTS at room temperature: green synthesis of 1,8-dioxooctahydroxanthene derivatives
Research on Chemical Intermediates - - 2021
Bipin Shinde, Santosh Kamble, Harsharaj Jadhav, Prasad Mane, Kalpesh Khude, Hern Kim, Bhausaheb Karale, Arvind Burungale
The biogenic synthesis of copper oxide nanoparticles (CuO NPs) from the leaf extract of Alpinia zerumbet was investigated in this protocol. The basic nature of A. zerumbet leaf extract helps in CuO NPs synthesis. The catalytic activity of A. zerumbet-fabricated CuO NPs is explored in water at room temperature only in the presence of NaPTS hydrotrope. The green catalytic protocol is investigated vi...... hiện toàn bộ
Synthesis of Sm-doped TiO2 nanotubes and analysis of their methylene blue-removal properties under dark and UV-irradiated conditions
Research on Chemical Intermediates - Tập 39 - Trang 1581-1591 - 2012
Dong Jin Park, Tohru Sekino, Satoshi Tsukuda, Shun-Ichiro Tanaka
TiO2 nanotubes (TNTs) have received much attention over the past decade because of their unique nanostructure and physicochemical properties; in particular, TNTs can be applied in photocatalysis. In this study, degradation of methylene blue (MB) by samarium (Sm)-doped TNTs synthesized by a soft chemical process was investigated. Transmission electron microscopy revealed TNTs had diameters of appro...... hiện toàn bộ

The α-Fe2O3/g-C3N4 composite as an efficient heterogeneous catalyst with combined Fenton and photocatalytic effects
Research on Chemical Intermediates - Tập 43 - Trang 3307-3323 - 2016
Sushan Ren, Changhong Chen, Yan Zhou, Qimei Dong, Hanming Ding
Integration of Fenton and photocatalytic processes in one reaction system may increase the degradation efficiency in wastewater treatments. In this work α- Fe2O3/g-C3N4 composites with different mass percentages of α-Fe2O3 have been prepared in order to catalyze the Fenton and photocatalytic reactions simultaneously. The catalytic efficiency is greatly boosted in the presence of H2O2 under visible...... hiện toàn bộ
Molecular orbital and DFT studies of the alimemazine radical cation
Research on Chemical Intermediates - Tập 26 - Trang 739-745 - 2000
Ke-Sheng Song, Lei Liu, Chen -Rui Hou, Xiao -Song Li, Qing -Xiang Guo
Semiempirical molecular orbital methods including CNDO, MNDO, AM1 and PM3, and density function theory method B3LYP/3-21G(d) were employed in the study of the alimemazine radical cation. It was found that PM3 was much better than CNDO, MNDO and AM1 in the structural optimization. The bond lengths and bond angles by PM3 were close to the experimental data, and comparable with the results by the den...... hiện toàn bộ

An efficient method for synthesis of 3-arylbenzo[f]quinoline-1,2-dicarboxylates catalyzed by SnCl2
Research on Chemical Intermediates - Tập 41 - Trang 6967-6974 - 2014
Qing Yan, Hongjun Zang, Jiaxuan Feng, Mingguang Li, Danni Yang, Hai Lu, Bowen Cheng
A wide variety of 3-arylbenzo[f]quinoline-1,2-dicarboxylates and their dehydro derivatives have been synthesized by one-pot, three-component reaction of an aromatic aldehyde, naphthalene-2-amine, and dimethyl but-2-ynedioate in the presence of SnCl2 under reflux in acetonitrile. This procedure has several advantages, for example high yield, short reaction time, easy work-up, little pollution, and ...... hiện toàn bộ
