EXAMPLE 3 Benzene diazonium fluoride was prepared substantially in accordance with the procedure of Example 1 except that the temperature of the refrigerated bath of glycol and water was maintained at plus 5.degree. C. The temperature of the reaction mixture exiting each static mixer in the first four sections was higher (35.degree. C., maximum temperature in each such section). The temperature of the reaction mixture exiting each static mixer in the last six sections was also higher (about 20.degree. C., maximum temperature in each such section). The resulting mixture exiting the cross-flow tubular reactor was a dark brownish-black solution. Analysis of the samples of the exiting stream showed presence of benzene diazonium fluoride in lower concentrations of from about 2.05 to about 2.17 g-moles per liter, corresponding to a diazonium fluoride yield of about 85 to 90% based on the amount of nitrosyl fluoride introduced into the reactor. |

示例3 氟化重氮苯的制备实质上按照程序例1进行，除了乙二醇和水冷却浴的温度保持在加+5℃以外。在前四个部分中每一个静态混合器出来的反应混合物的温度较高(在每个这样部分的最高温度35℃)。在后六个部分中每一个静态混合器出来的反应混合物的温度也较高(在每个这样的部分的最高温度20℃)。流出横流式管式反应器所产生的混合物是黑暗的棕黑色的溶液。流出的样品的分析表明，氟化重氮苯的浓度比较低，大约从2.05摩尔每升到约2.17摩尔每升，相当于氟重氮物产率约85％至90％，是基于进入反应器的亚硝酰基氟的量计算的。 |
