| titleOfInvention | Process for producing isoprenol |
| 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. |
