Research speed reading in 2021. In classical electrochemical theory, both the electron transfer rate and the adsorption of reactants at the electrode control the electrochemical reaction. 15988-11-1, name is 4-Phenyl-1,2,4-triazolidine-3,5-dione belongs to triazoles compound, it is a common compound, a new synthetic route is introduced below. Safety of 4-Phenyl-1,2,4-triazolidine-3,5-dione

General procedure: A mixture of dimedone (1, 1 mmol), 4-phenylurazole (2, 1 mmol), aromatic aldehyde (3a-h, 1mmol) and S-LCCO nano perovskite (0.01 g) was mixed in a high-pressure Teflon reactor, which was equipped with a magnetic stirrer and an optical fiber, which was implemented to control the reaction’s temperature. The reaction mixture was irradiated by 400 W microwave at 80 oC, for the specified reaction times. TLC with n-hexan:ethylacetate eluent was used to monitor the progress of the reactions. After reaction completion and cooling, the reaction mixtures were filtered and washed with ethanol to separate the catalyst. First, 10 mL water was added to the solution. Then, EtOH/H2O (4:1) was added to crystallize the water insoluble crude products. Then the crystals were filtered to achieve pure products (4a-h).

Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law. In my other articles, you can also check out more blogs about 15988-11-1, and we look forward to future research findings.

Research speed reading in 2021. The dynamic chemical diversity of the numerous elements, ions and molecules that constitute the basis of life provides wide challenges and opportunities for research. 15988-11-1, name is 4-Phenyl-1,2,4-triazolidine-3,5-dione belongs to triazoles compound, it is a common compound, a new synthetic route is introduced below. Computed Properties of C8H7N3O2

General procedure: Dimedone (0.14 g, 1 mmol), benzaldehyde (0.1 g, 1 mmol), and 4-phenylurazole (0.177 g, 1 mmol) were mixed with PEG-SO3H (0.6 g, 0.1 mmol) and the obtained mixture was stirred magnetically at 80 C for 40 min. After the completion of the reaction warm water (20 mL) was added and the mixture stirred for about 5 min. The insoluble crude product was filtered and recrystallized from EtOH/H2O 4:1 and the pure product was obtained (0.352 g, 91%). In order to recover the catalyst, the filtrate was dried under reduced pressure and recovered catalyst was washed with diethyl ether and reused after drying under reduced pressure. The equivalent procedure was used for the synthesis of triazolo[1,2-a]indazole-tetraones.

The catalyzed pathway has a lower Ea, but the net change in energy that results from the reaction is not affected by the presence of a catalyst. In my other articles, you can also check out more blogs about 15988-11-1
