[0002] Isobutyl alcohol polyoxyethylene ether is a non-ionic surfactant and belongs to polyether compounds. It is prepared by addition polymerization of isobutyl alcohol and ethylene oxide under the action of a catalyst. It has hydrophilic and lipophilic properties due to the presence of isobutyl and polyoxyethylene segments in its chemical structure, and it has very wide applications in industry.

[0003] Isobutyl alcohol polyoxyethylene ether is usually produced in a micro-channel reaction device, which is a device that utilizes micro-channels for chemical reactions.

[0042] A method for cleaning a microchannel reaction device comprises the following steps: Step 1: Unlocking the movable closing platform 2: Push the two unlocking plates 3 toward each other to unlock the movable closing platform 2; Step 2: Move the movable closing platform 2 upwards: pull the movable closing platform 2 upwards; Step 3: Cleaning the closed surface of the movable closing table 2: The movable closing table 2 drives the cleaning movable frame 4 to move to achieve cleaning of the closed surface of the movable closing table 2; Step 4: Cleaning the inner wall of the microchannel 11: The movable closing platform 2 drives the supporting movable bar 6 to move to clean the inner wall of the microchannel 11; Step 5: Fixing the movable closing table 2: When the movable closing table 2 moves up to the working point, the unlocking plate frame 3 is released to fix the movable closing table 2, and the movable closing table 2 and the microchannel 11 can be further cleaned.

[0043] During the process of closing the movable closing table 2 with the reaction base 1, the sealing matching strip 12 will be inserted into the sealing matching channel 21 to achieve the sealing of both sides of the microchannel 11. At the same time, under the restriction of the sealing matching strip 12, it contacts the filling frame 52, which will make the supporting movable strip 5 no longer move, so that the supporting movable strip 5 and the movable closing table 2 move relative to each other. When it is necessary to clean the closed surface of the microchannel 11 and the movable closing table 2, hold the matching hand frame 23 to move the unlocking plate frame 3 in the direction of the matching hand frame 23. As the unlocking plate frame 3 moves, the matching connecting rod Under the action of 33, the ejection plate 34 will be driven to move, so that the ejection plug-in rod 37 will be inserted into the limited through-hole 29, so that under the action of the ejection plug-in rod 37, the limited plug-in rod 47 will be pushed to move, so that the limited plug-in rod 47 will exit the limited through-hole 29. At this time, the movable closing table 2 is in the unlocked state, and the movable closing table 2 is pulled upward, which will drive the clearing movable frame 4 to move upward as well, so that the distance between the clearing movable frame 4 and the connecting matching top block 15 becomes smaller, so that the clearing movable frame 4 can be pushed to move under the action of the driving connecting rod 49 to close the movable closing table 2. The closed surface of the movable closing table 2 is cleaned, and as the movable closing table 2 moves upward, the lower end surface of the filling frame 52 is flush with the lower end surface of the movable closing table 2, so that the cleaning inclined surface 41 on the cleaning movable frame 4 will not push impurities into the sealing matching channel 21 when cleaning the closed surface of the movable closing table 2, and as the movable closing table 2 moves upward, the supporting movable bar 6 will be driven to move under the action of the connecting loading rod 611, so that the pushing cleaning plate 63 and the pushing cleaning frame 64 are inserted into the microchannel 11 to clean the impurities on the inner wall of the microchannel 11. When the movable closing table 2 moves up to the working When the lock is in the closed position, the unlocking plate frame 3 is released, and the limited movable plate 46 can be reset under the action of the matching spring 48, so that the limited plug-in rod 47 is inserted into the limited through hole 29 close to the side of the movable closing table 2, thereby fixing the movable closing table 2. At the same time, under the action of the limited plug-in rod 47, it will push the pushing strip 34 to reset, thereby driving the unlocking plate frame 3 to reset. Then the staff can further clean the microchannel 11, which is very convenient. After the cleaning is completed, push the unlocking plate frame 3 again to make the movable closing table 2 in the unlocked state, and move it down to reset.
