80841-78-7,Chemistry can be defined as the study of matter and the changes it undergoes. You¡¯ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.4-(Chloromethyl)-5-methyl-1,3-dioxol-2-one,introducing its new discovery.
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).
Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. I hope my blog about 80841-78-7 is helpful to your research. 80841-78-7
