    Abstract: 一种生产异戊烯醇的方法,包括通过多个平行操作的喷嘴将甲醛源和异丁烯混合并注入反应器中并使甲醛源和异丁烯在超临界条件下反应;其中该反应器包括垂直放置的容器、侧壁、上部和下部;并且其中将甲醛源和异丁烯注入设置在上部的反应器混合室中并将包含甲醛和/或异丁烯和/或异戊烯醇的流体从该混合室送入设置在下部的后反应室中;以及在该混合室中提供在各喷嘴之下基本同心排列的通流管,其中通流管提供在通流管之内的降液管和在通流管之外的升气管,从而使通过喷嘴注入的甲醛源和异丁烯在降液管中通常向下移动,包含甲醛和/或异丁烯和/或异戊烯醇的流体则在升气管中在通常向上的方向上转向,并且使该流体与注入的甲醛源和异丁烯返混。该方法允许以高选择性和高产率得到异戊烯醇。本发明还涉及一种反应器,包括:垂直放置的容器,侧壁,上部和下部,将设置在上部的反应器混合室和设置在下部的后反应室分隔的多孔板;多个将流体以基本向下的方向注入该混合室中的喷嘴;在该混合室中的各喷嘴之下基本同心排列的通流管,其中通流管提供在通流管之内的降液管和在通流管之外的升气管,从而使通过喷嘴注入的流体在降液管中通常向下移动,已反应流体则在升气管中在通常向上的方向上转向,并且使该流体与注入的流体返混;和在后反应室中的流体出口。

    Abstract: A process for producing isoprenol, comprising: mixing and injecting a formaldehyde source and isobutylene into a reactor through a plurality of nozzles operated in parallel and reacting the formaldehyde source and isobutylene under supercritical conditions; wherein the reactor comprises a vertically disposed vessel, a sidewall, an upper portion and a lower portion; and wherein the formaldehyde source and isobutylene are injected into a mixing chamber of the reactor disposed in the upper portion and a fluid comprising formaldehyde and/or isobutylene and/or isoprenol is passed from the mixing chamber into a post-reaction chamber disposed in the lower portion; and providing draft tubes arranged essentially concentrically underneath each of the nozzles in the mixing chamber, the draft tubes providing downcomer conduits within the draft tubes and a riser conduit outside of the draft tubes, so that the formaldehyde source and isobutylene injected through the nozzles travel generally downward in the downcomer conduits, a fluid comprising formaldehyde and/or isobutylene and/or isoprenol is then diverted in a generally upward direction in the riser conduit, and the fluid is back-mixed with the injected formaldehyde source and isobutylene. The process allows for isoprenol to be obtained with high selectivity and in high yields. The invention also relates to a reactor comprising: a vertically disposed vessel, a sidewall, an upper portion and a lower portion, a perforated plate separating a mixing chamber of the reactor disposed in the upper portion and a post-reaction chamber disposed in the lower portion; a plurality of nozzles for injecting a fluid into the mixing chamber in an essentially downward direction; draft tubes arranged essentially concentrically underneath each of the nozzles in the mixing chamber, the draft tubes providing downcomer conduits within the draft tubes and a riser conduit outside of the draft tubes, so that the fluid injected through the nozzles travels generally downward in the downcomer conduits, a reacted fluid is then diverted in a generally upward direction in the riser conduit, and the fluid is back-mixed with the injected fluid; and a fluid outlet in the post-reaction chamber.
