EXAMPLE 4 Diazotization of Aniline in a Cross-Flow Recycle Reactor 9.11 kg (97.96 g-moles) of aniline was added with stirring to 11.77 kg (588.5 g-moles) of HF in tank 34 while maintaining a temperature of 5.degree. C. via cooling water, thereby forming a solution of aniline-HF at a 1 to 6 molar ratio. Then 6.76 kg (97.97 g-moles) of sodium nitrite were added with stirring to 23.51 kg (1173 g-moles) of HF in tank 36 while maintaining a temperature of 2.degree. C. via cooling water, thereby forming a solution of nitrosyl fluoride in HF at a 1 to 12 molar ratio. The aniline-HF solution was fed continuously to the multi-stage reactor for one hour at 25.degree. C. at a flow rate of 200 ml/min. Once the multi-stage reactor was filled with aniline-HF the recycle pump 64 was set to deliver 2,050 ml/min. or a 4.81 mass ratio of recycled to total mass in. The nitrosyl fluoride-HF solution was injected incrementally into lines 38, 44 and 48 immediately prior to each of the three static mixers. The proportions of nitrosyl fluoride fed to static mixer 58, 74 and 68 respectively, were 50%, 40% and 10%. The nitrosyl fluoride solution was fed continuously for one hour at 10.degree. C. by pressurizing tank 36 and controlling the flow rate at 209 ml/min. via a control valve (not shown) allowing approximately 7% of the feed aniline to exit at 70 unconverted. The temperature of the reaction mixture was maintained by pumping a solution of glycol and water, maintained at 5.degree. C. by a chiller, through heat exchangers 60 and 62. The cooling solution flow was maintained such that the temperature of the reaction mixture was between 5 and 25.degree. C. in the first two reaction sections and between 5 and 18.degree. C. in the third reaction section. The completely reacted reaction mixture leaving the recycle reactor was a clear brownish-orange solution that was collected for further processing to produce fluorobezene. Test samples of the reaction mixture were collected every five minutes. Of the samples taken, the concentration of benzene diazonium fluoride was between 2.59 g-mole/liter and 2.61 g-mole/liter, corresponding to a conversion of between 98% and 100% of aniline to benzene diazonium fluoride, based on nitrosyl fluoride injected. |

EXAMPLE 4 示例4 Diazotization of Aniline in a Cross-Flow Recycle Reactor 在错流循环反应器中苯胺的重氮化 9.11 kg (97.96 g-moles) of aniline was added with stirring to 11.77 kg (588.5 g-moles) of HF in tank 34 while maintaining a temperature of 5.degree. C. via cooling water, thereby forming a solution of aniline-HF at a 1 to 6 molar ratio. 在通入冷却水保持5℃、已有11.77公斤（588.5摩尔）HF的反应罐34中，伴随搅拌加入9.11公斤(97.96摩尔)苯胺，从而形成了摩尔比在1至6的苯胺-HF溶液。 |

苯胺- HF溶液连续输送到25℃的多级反应器，时间为一小时，流速为200毫升/分钟。 Once the multi-stage reactor was filled with aniline-HF the recycle pump 64 was set to deliver 2,050 ml/min. or a 4.81 mass ratio of recycled to total mass in. 一旦苯胺HF充满了多级反应器，循环泵64被设置为2,050毫升/分钟，或按总质量循环，其质量比为4.81。 The nitrosyl fluoride-HF solution was injected incrementally into lines 38, 44 and 48 immediately prior to each of the three static mixers. 把亚硝基氟-HF溶液依次注入三个静态混合器前的管线38、44和48。 The proportions of nitrosyl fluoride fed to static mixer 58, 74 and 68 respectively, were 50%, 40% and 10%. 按50％、40％和10％的比例将亚硝基氟分别输送到静态混合器58、74和68。 The nitrosyl fluoride solution was fed continuously for one hour at 10.degree. C. by pressurizing tank 36 and controlling the flow rate at 209 ml/min. via a control valve (not shown) allowing approximately 7% of the feed aniline to exit at 70 unconverted. 把亚硝基氟溶液用一小时在10℃连续输送，通过密封罐36中，且流速控制在209毫升/分钟，是通过控制阀（未显示），使大约7％的苯胺进料输出(未转化的)70。 |

反应混合物方案温度的维持是由泵入经由冷却器5℃的乙二醇和水的溶液，通过了热交换器60和62。 保持冷却的溶液的流量，这样在前两个反应阶段中反应混合物的温度在5至25℃，第三反应阶段在5和18℃之间。 流出循环反应器的完全反应的反应混合物是淡的棕橙色溶液，收集再进一步加工生产氟苯。 每五分钟收集反应混合物的样品。 所获得的样品，氟化重氮苯浓度在2.59摩尔/升到2.61 摩尔/升之间，基于注入亚硝基氟计算，相当于苯胺生成氟化重氮苯转化率的98％到100％之间。 |
