EXAMPLE 2 The procedure of Example 1 was repeated except that the total flow of HF solution of nitrosyl fluoride was injected via 7 approximately equal flows of 43 to 50 ml/minute through the inlets of the 7 downstream static mixers and the temperature of the refrigerated bath of glycol and water was maintained at minus 8.degree. C. The temperature of the reaction mixture entering the second and each successive static mixer was essentially unchanged (about 5.degree. C.); the temperature of the reaction mixture exiting each static mixer in the first four sections was unchanged (about 25.degree. C.); and the temperature of the reaction mixture exiting each static mixer in the three downstream sections into which the fifth, sixth and seventh flows of the nitrosyl fluoride solution were injected was about 15.degree. C. (the maximum temperature in each such section). The resulting mixture exiting the tubular reactor was substantially the same as the resulting mixture in Example 1, including (a) clear brownish-orange solution, (b) concentrations of benzene diazonium fluoride of about 2.36 to 2.41 g-moles per liter, and (c) diazonium fluoride yield of 98 to 100% based on the amount of nitrosyl fluoride introduced into the reacto |

示例2 重复示例1，不同的是，通过7注入的亚硝基氟的HF溶液的总流量在7下游静态混合器的入口约等于43至50毫升/分钟，并且乙二醇和水的冷却浴的温度保持在零下8℃。进入第二个和每一个连续的静态混合器的反应混合物的温度基本上是不变的(约5℃)；流出前四个部分的每一个静态混合器的反应混合物的温度基本上不变（约25℃)；并且流出在3个下游的进入第五，第六和第七段的亚硝基氟溶液的反应混合物的温度约15℃(在这里每个部分的最高气温)。流出管式反应器的产物混合物和例1中得到的混合物大致相同,包括：(a)透明的深橙色溶液，(b)氟化苯重氮的浓度约2.36至2.41摩尔每升，和(c)基于进入反应器的亚硝基氟的量计算氟化重氮物的产率为98至100％。 |
