After phase separation the organic phase (1200kg) is separated into two halves (600kg each). From the first half of the organic phase solvent (172kg) is distilled off at a temperature of about 40 to 50°C (p=200mbar). Then 2-propanole (640kg) is added. The solution is heated to about 50°C and then filtered through a charcoal cartouche (clear filtration). The cartouche may be exchanged during filtration and washed with a fluorobenzene/2-propanole mixture (1 :4; 40kg) after filtration. Solvent (721 kg) is distilled off at a temperature of about 40 to 50°C and p=200mbar. Then 2-propanole (240kg) is added at a temperature in the range between about 40 to 50°C. If the content of fluorobenzene is greater than 1 percent as determined via GC, another 140kg of solvent are distilled off and 2-propanole (140kg) is added. Then the solution is cooled from about 50°C to 40°C within one hour and seeding crystals (50g) are added. The solution is further cooled from about 40°C to 20°C within 2 hours. Water (450kg) 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 ; 800kg). The product is dried until a water level of <0.06percentw/w is obtained. The second half of the organic phase is processed identically. A total of 410kg (94percentyield) of product which has a white to off-white crystalline appearance, is obtained. The identity of the product is determined via infrared spectrometry. The synthetic route of 19094-56-5 has been constantly updated, and we look forward to future research findings. Reference:
