Preparation technology of phenylboronic acid reaction liquid

The invention discloses a preparation technology of phenylboronic acid reaction liquid, and relates to the technical field of chemical preparation. The preparation technology comprises the following steps of under the protection of nitrogen, enabling anhydrous tetrahydrofuran, iodobenzene and n-BuLi to be subjected to an interaction so as to prepare layered reaction liquid; then through triisopropyl borate, hydrochloric acid and MTBE, obtaining an organic matter; and finally performing extraction and separation on the organic matter so as to obtain phenylboronic acid crude products. The preparation technology is simple in technological process and short in period, mass production requirements can be met, besides, the preparation period is short, and the working efficiency is high. 本发明公开了种苯硼酸的反应液的制取工艺，它涉及化学制造技术领域；在氮气保护下，无水四氢呋喃、碘苯、n-BuLi的相互反应制备层成反应液；在通过与硼酸三异丙酯、盐酸、MTBE得到有机物，最后通过对有机物的萃取分离得苯硼酸粗品；它工艺流程简单，制备工艺周期较短，能够满足大批量生产需求，而且制备周期短，工作效率高。
