| titleOfInvention | Method for producing prenol |
| abstract | A method of producing prenol, comprising mixing and injecting a formaldehyde source and isobutene through a plurality of nozzles operating in parallel into a reactor and reacting the formaldehyde source and isobutene under supercritical conditions; wherein the reactor comprises a vertically placed container, side walls, upper part and lower part; and wherein the formaldehyde source and isobutylene are injected into the reactor mixing chamber provided in the upper part and the fluid containing formaldehyde and/or isobutylene and/or prenol is sent from the mixing chamber into the setting in the lower post-reaction chamber; and in the mixing chamber are provided substantially concentrically arranged draft tubes below each nozzle, wherein the draft tubes provide downcomers inside the draft tubes and outside the draft tubes The chimney so that the formaldehyde source and isobutene injected through the nozzles travel generally downwards in the downcomer, and the fluid containing formaldehyde and/or isobutene and/or prenol moves in the chimney in a generally upward direction Diverted and backmixed the fluid with the injected formaldehyde source and isobutylene. This process allows to obtain prenol with high selectivity and yield. The present invention also relates to a reactor, comprising: a vertically placed container, a side wall, an upper part and a lower part, a perforated plate separating the reactor mixing chamber arranged at the upper part and the rear reaction chamber arranged at the lower part; nozzles in the mixing chamber injected in a substantially downward direction; draft tubes arranged substantially concentrically below each nozzle in the mixing chamber, wherein the draft tubes provide downcomers within the draft tubes and in the draft tubes A riser outside the tube, whereby the fluid injected through the nozzle travels generally downward in the downcomer, the reacted fluid is turned in a generally upward direction in the riser, and backmixes the fluid with the injected fluid ; and a fluid outlet in the post-reaction chamber. |
