The major producers of chemicals have been the Europe, Japan and China. Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a compound 6515-09-9, name is 2,3,6-Trichloropyridine. This compound has unique chemical properties. The synthetic route is as follows. COA of Formula: C5H2Cl3N
In a 1000 ml stainless steel autoclave, 50 g of 2,3,6-trichloropyridine was added.300g of methanol, 35g of triethylamine, and then added 0.05g of 10% palladium carbon.First replace the air in the kettle three times with nitrogen, and then replace it three times with hydrogen.Pressurize to 4.0Mpa and control the temperature at 45~50C.The reaction speed was set to 300 rpm/min, and hydrogen was continuously added during the reaction.The reaction pressure was maintained at 3.0 to 4.0 MPa, and the reaction was stopped after 4 hours of reaction.Cooling, sampling for liquid phase quantitative detection and analysis,The conversion rate of raw material 2,3,6-trichloropyridine is 96.5%.The selectivity to 2,3-dichloropyridine was 86.7%. After filtering the reaction solution,After rectifying and removing the reaction solvent, after adding a moisture layer,The organic phase was subjected to rectification to obtain 33.1 g of a white 2,3-dichloropyridine product.The product purity is 99.5%.
With the rapid development of chemical substances, we look forward to future research findings about 6515-09-9.
