Solvent (721 kg) is distilled off at a temperature of about 40 to 50 C. and p=200 mbar. Then 2-propanole (240 kg) is added at a temperature in the range between about 40 to 50 C. If the content of fluorobenzene is greater than 1% as determined via GC, another 140 kg of solvent are distilled off and 2-propanole (140 kg) is added. Then the solution is cooled from about 50 C. to 40 C. within one hour and seeding crystals (50 g) are added. The solution is further cooled from about 40 C. to 20 C. within 2 hours. Water (450 kg) is added at about 20 C. within 1 hour and the suspension is stirred at about 20 C. for an additional hour before the suspension is filtered. The filter cake is washed with 2-propanole/water (1:1; 800 kg). The product is dried until a water level of <0.06% w/w is obtained. The second half of the organic phase is processed identically. A total of 410 kg (94% yield) of product which has a white to off-white crystalline appearance, is obtained. The identity of the product is determined via infrared spectrometry.
