Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 456-55-3, name is (Trifluoromethoxy)benzene, A new synthetic method of this compound is introduced below., COA of Formula: C7H5F3O
Example 2 4-Chloromethyl-1-trifluoromethoxybenzene 200 g of trifluoromethoxybenzene and 48 g of paraformaldehyde were dissolved in 500 ml of methanol, and dry hydrogen chloride gas was introduced at 60 C. for 7 hours. The waste gases were, via a reflux condenser, passed into aqueous ammonia. The reaction mixture was then poured onto 1,000 g of ice and extracted twice with in each case 300 ml of methyl tert-butyl ether. The combined extracts were washed with 100 ml of water and then with 100 ml of sodium bicarbonate solution and subsequently concentrated. The residue was distilled at 18 hPa in a spinning band column. This gave 158.8 g of 4-chloromethyl-1-trifluoromethoxybenzene as a colorless liquid (65% of theory) of b.p. 71-74 C.
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
