On May 25, 2020, Kulal, Nagendra; John, Crowny; Shanbhag, Ganapati V. published an article.Recommanded Product: 1,3-Diphenylurea The title of the article was Rational design of bifunctional catalyst from KF and ZnO combination on alumina for cyclic urea synthesis from CO2 and diamine. And the article contained the following:

This study is mainly focused on the design of stable, active and selective catalyst for direct synthesis of 2-imidazolidinone (cyclic urea) from ethylenediamine and CO2. Based on the rationale for the catalyst properties needed for this reaction, KF, ZnO and Al2O3 combination was selected to design the catalyst. ZnO/KF/Al2O3 catalyst was prepared by stepwise wet-impregnation followed by the removal of physisorbed KF from the surface. High product yield could be achieved by tuning acid-base sites by varying the composition and calcination temperature The catalysts were characterized by various techniques like XRD, N2-sorption, NH3-TPD, CO2-TPD, TEM, XPS and FT-IR measurements. It is shown that acidic and basic properties of the solvent can influence the activity and product selectivity for this reaction. Under optimized condition; 180°C, 10 bar and 10 weight% catalyst in batch mode, 96.3% conversion and 89.6% selectivity towards the 2-imidazolidinone were achieved. The experimental process involved the reaction of 1,3-Diphenylurea(cas: 102-07-8).Recommanded Product: 1,3-Diphenylurea

On July 25, 2021, Dahnum, Deliana; Dang, Huyen Tran; Tran, Ngoc Tuan; Ha, Jeong-Myeong; Lee, Hyunjoo published an article.Electric Literature of 102-07-8 The title of the article was One-pot synthesis of 3D-ZIF-7 supported on 2D-Zn-Benzimidazole-Acetate and its catalytic activity in the methoxycarbonylation of aniline with dimethyl carbonate. And the article contained the following:

For the first time, three-dimensional Zeolitic Imidazole Framework (3D) ZIF-7 (Zn(BeIM)2, BeIM = benzimidazole) supported on two-dimensional (2D) Zn(BeIM)OAc (Zinc-Benzimidazole-Acetate) was synthesized by reacting Zn(OAc)2 and benzimidazole in a one-pot reaction. By modulating the amount of diethylamine during the reaction, the ZIF-7/Zn(BeIM)OAc with a 1 to 1 molar ratio was obtained when the reactant molar ratio of Zn(OAc)2 and benzimidazole was 1 to 1.5. It was found that 3D-ZIF-7 was synthesized first and then transformed into 2D-Zn(BeIM)OAc by the reaction with remaining Zn(OAc)2. The synthesized ZIF-7 (Zn(BeIM)2) supported on Zn(BeIM)OAc (1/1) showed enhanced catalytic performance in the methoxycarbonylation of aniline with di-Me carbonate. The yield of Me N-Ph carbamate reached 92.0% in 2 h at 190°C, which was higher than yields obtained using the single component catalysts ZIF-7 (69.9%) and Zn(BeIM)OAc (35.4%). Furthermore, this catalyst was successfully reused four times, maintaining an MPC yield of 92.0%-95.8%.

These solid acids were used as catalysts in the solvent-free synthesis of biphenyl urea using microwave irradiation technique starting from aniline and di-Me carbonate. Surface acidity and the phase of the solid acid were found to have a significant role in the synthesis of biphenyl urea. Up to (98%) yield of biphenyl urea with 100% selectivity was obtained in just 12 min. The activity of ZrO2-Al2O3 was compared with Mo(VI)/ZrO2 which is a solid super acid. For comparison, the reactions were also carried out by using conventional heating method. Kinetic studies were carried out to determine energy of activation of the solid acids. These solid acid catalysts were found to be reactivable and reusable when used for up to six reaction cycles.
