摘要： Conventional plant to produce peroxomonosulphuric acid (Caro's acid) is large and emphasises extensive cooling, so that it is awkward to transport, can be cumbersome to install beside existing plant and can suffer from relatively expensive capital and/or running costs.In the present invention, Caro's acid is generated continuously in relatively small plant adiabatically, by introducing concentrated hydrogen peroxide into a stream of concentrated sulphuric acid in a reaction chamber dimensioned so that the throughput is very fast. In particularly suitable embodiments, the reaction chamber is annular at the points of introduction of the reagents, its width being greater in the vicinity of the hydrogen peroxide inlet than in the vicinity of the sulphuric acid inlet. The hydrogen peroxide inlet is preferably angled backwardly so that its encounter angle with the sulphuric acid stream is over 90.degree. to about 165.degree..
摘要翻译：生产过氧硫酸（Caro's acid）的传统工厂很大，并且强调大量的冷却，因此运输是尴尬的，安装在现有工厂旁边可能很麻烦，并且可能遭受相对昂贵的资金和/或运行成本。在本发明中，通过将浓缩的过氧化氢引入反应室中的浓硫酸流中，绝热地在相对较小的植物中连续生成Caro酸，其尺寸使得生产量非常快。在特别合适的实施方案中，反应室在试剂引入点处是环形的，其宽度在过氧化氢入口附近比在硫酸入口附近更大。过氧化氢入口优选地向后倾斜，使得其与硫酸流的碰撞角超过90度至约165度。
