80841-78-7, A balanced equation for a chemical reaction indicates what is reacting and what is produced, but it reveals nothing about how the reaction actually takes place. The reaction mechanism is the process, or pathway, by which a reaction occurs.80841-78-7. An updated downstream synthesis route of 80841-78-7 as follows.
The reaction flask was charged with 697.5 g of compound V obtained in the previous step,414 g of anhydrous potassium carbonate (3.00 mol)163.4 g of 4-chloromethyl-5-methyl-1,3-dioxol-2-one (Compound VI) (1.10 mol)And 2500 ml of acetonitrile were refluxed for 2 hours,After the reaction,filter,The filtrate was concentrated to dryness,The residue was stirred in 1500 ml of ethyl acetate and 500 ml of water for 15 minutes,Layered, organic layer and then washed with water,Dried over anhydrous sodium sulfate,filter,The filtrate was concentrated to dryness,To give the crude product of compound VII,Recrystallization from toluene and petroleum ether,To obtain pure product 683.2 grams; two-step yield:85.40% (calculated as compound II).
The chemical industry reduces the impact on the environment during synthesis, 4-(Chloromethyl)-5-methyl-1,3-dioxol-2-one, , I believe this compound will play a more active role in future production and life.
