Chemistry is the experimental and theoretical study of materials on their properties at both the macroscopic and microscopic levels. 80841-78-7. In a patent£¬Which mentioned a new discovery about 80841-78-7, molcular formula is C5H5ClO3, introducing its new discovery.
10L autoclave, 520g (0.75mol) Compound 5, DMF3kg, potassium carbonate and 215.3g (1.6mol), stirred at room temperature 1.5-2.5h added to the system after 63.0g (0.38mol) of potassium iodide was added dropwise while – Chloromethyl -5-methyl-1,3-dioxol-2-one 40.0g (0.94mol). Dropping was completed, the reaction at room temperature after 3-4h TLC or HPLC in control, raw reaction was complete. To the system was added ethyl acetate and 3L 3L water and 200g of sodium chloride, stirring separated and the aqueous layer was washed with 3X1L ethyl acetate, the combined organic layers, the organic layer was dried, filtered and the solvent was evaporated cooling is added 0-10 , methanol was added 1600g beating 30min, filtered, then the filter cake was slurried at room temperature in acetonitrile 1600g 30min, filtered to afford intermediate 6 about 553.8g,
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 4-(Chloromethyl)-5-methyl-1,3-dioxol-2-one.C5H5ClO3
