专利号:US-2022411943-A1 优先权日:2021-06-23 标 题 :Process for the Electrochemical Synthesis of Green Urea, an Electrochemical Cell for the Electrochemical Synthesis of Green Urea and the Green Urea Produced Thereby 发明人:GHORAI UTTAM KUMAR; MUKHERJEE Jit; PAUL SOURAV; ADALDER ASHADUL 权利人:GHORAI UTTAM KUMAR; RAMAKRISHNA MISSION VIDYAMANDIRA 摘要:This invention relates to a process for the electrochemical synthesis of green urea, and the urea produced thereby. The electrochemical synthesis of urea involves the reduction of dual purging gases N 2 and CO 2 via six electron transfer process (N 2 +CO 2 +6H + +6e − →CO (NH 2 ) 2 +H 2 O) & reduction of the NO 3 − ions and CO 2 via sixteen electron transfer process (2NO 3 −+CO 2 +18H + +16e − →CO(NH 2 ) 2 +7H 2 O) under ambient condition using copper phthalocyanine (CuPc) catalyst. The binding of two intermediate products during dual reduction simultaneously, leads to the production of urea in water medium under ambient conditions.

Irradiation of single mode, high power, microwave is a particularly well suited technique to realize high quality semiconductor nanoparticles. The use of microwave radiation effectively automates the synthesis, and more importantly, permits the use of a continuous flow microwave reactor for commercial preparation of the high quality colloidal nanoparticles.

The process is simple, economical, and produces alkyl 2-(3-chloropyridin-2-yl)-5-oxo-pyrazolidine-3-carboxylate with a comparatively high yields.
专利号:US-2023279562-A1 优先权日:2021-12-30 标题 :Process for the Electrochemical Synthesis of Ammonia (NH3) and the Ammonia Produced Thereby 发明人:GHORAI UTTAM KUMAR; PAUL SOURAV; ADALDER ASHADUL; SARKAR SOUGATA 权利人:GHORAI UTTAM KUMAR; RAMAKRISHNA MISSION VIDYAMANDIRA 摘要:This invention relates to a process for the electrochemical synthesis of ammonia (NH3) and the ammonia produced thereby. Ammonia is synthesized by the electrochemical reduction of nitrogenous materials such as nitrogen or nitrates (NO3-) using metal phthalocyanine such as iron phthalocyanine (FePc) or β-cobalt phthalocyanine (CoPc) or iron phthalocyanine-molybdenum disulfide (FePc-MoS2) or cobalt phthalocyanine- carbon nitride (CoPc-C3N4) catalyst at very low pressure and room temperature by applying low potential.
