Reference of 320-50-3, The chemical industry reduces the impact on the environment during synthesis 320-50-3, name is 1,4-Dichloro-2-(trifluoromethyl)benzene, I believe this compound will play a more active role in future production and life.
EXAMPLE 8 4-Chloro-2-trifluoromethylphenol To a 300 ml, 3-necked flask fitted with a stirrer, condenser, thermometer and drying tube is added dimethylsulfoxide (100 ml), tert-butanol (20 ml), powdered potassium hydroxide (KOH) pellets (85%, 30 g) and 2,5-dichlorobenzotrifluoride (21.5 g, 0.10 mole). The reaction mixture is warmed to 71-73 C. for 60 hours, then additional KOH (10 g) is added and heating is continued at 73-75 C. for 24 hours. The reaction mixture is cooled and the solvent partially removed by distillation at 0.9 mm, bp 55 C.). The cooled pot residue is then poured into ice water (1000 g) which had been preacidified to pH 1 with conc. HCl (50 ml). The aqueous mixture is extracted with carbon tetrachloride (CCl4), the CCl4 layer decanted and dried and the solvent removed under vacuum to afford 10.8 g of 4-chloro-2-trifluoromethylphenol, which is sublimed to afford pure product, mp 81-81.5 C. Elemental Anal. Calcd for C7 H4 ClF3 O: C, 42.75; H, 2.06; Cl, 18.04: Found: C, 42.54; H, 2.36; Cl, 18.16. STR14
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 1,4-Dichloro-2-(trifluoromethyl)benzene, other downstream synthetic routes, hurry up and to see.
