80841-78-7, The molecularity is the number of molecules that collide during that step in the mechanism. If only a single reactant molecule in an elementary reaction, that step is designated as unimolecular; if there are two reactant molecules, it is bimolecular.80841-78-7. A new synthetic method of this compound is introduced below.
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.
