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.
Example 4; The reaction was carried out in the same manner as in Example 1 except that 4- (1-hydroxy-1-methylethyl) -2-propyl-1- {4- [2- (trityltetrazol-5-yl) phenyl] -carboxylic acid sodium salt (Chemical Formula 5) and 50 mL of N, N-dimethylacetamide were added, the temperature was adjusted to 5 to 10 DEG C and 4 g of potassium carbonate was added. A solution of 6.2 g of 4- (chloromethyl) -5-methyl-1,3-dioxol-2-one (Formula 6) in 6 mL of N, N-dimethylacetamide was added dropwise to the reaction portion, For 4 hours. After the reaction was completed, the reaction solution was cooled to 20 to 25 C, and then 220 mL of ethyl acetate, 30 g of salt, and 170 mL of purified water were sequentially added to the reaction mixture, followed by separation of the organic layer, followed by the addition of 30 g of salt and 170 mL of purified water . & Lt; / RTI & gt; 1 g of activated carbon and 20 g of anhydrous sodium sulfate were added to the organic layer, followed by stirring for 30 minutes to 1 hour, followed by filtration. The filtrate was concentrated under reduced pressure, and 100 mL of acetonitrile was added to the residue, followed by stirring at 50 to 55 DEG C for 1 hour. The crystals were cooled to 0 to 5 C., stirred for 2 hours, filtered, washed with 50 mL of isopropyl alcohol and dried to obtain 21.7 g (yield: 93%, purity: 99.96%) of tritylolemethanemethoxysilane
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.
