| titleOfInvention | Preparation device and preparation method of cyanohydrin |
| abstract | The invention provides a preparation device and a preparation method of cyanohydrin, wherein the device comprises a feeding device, a shell, an upper end enclosure, a lower end enclosure, a reaction tube and a liquid level meter, wherein two ends of the shell are respectively connected with the upper end enclosure and the lower end enclosure; the reactor is characterized in that a baffle is arranged in the shell, the reaction tube is filled with filler, the upper end enclosure is provided with a liquid distributor close to the shell, and the lower end enclosure is provided with a baffle plate. The preparation method comprises the steps of feeding, entering a reactor and discharging; the feeding is as follows: the method comprises the following steps of feeding 3-methylmercapto-propionaldehyde serving as a raw material into a pipeline through a first Venturi nozzle, feeding hydrocyanic acid serving as a raw material into the pipeline through a hydrocyanic acid material inlet, feeding the hydrocyanic acid into a liquid distributor, feeding the hydrocyanic acid into corresponding reaction tubes through distribution holes of the liquid distributor, filling materials in the reaction tubes, discharging after reaction, and controlling the reaction yield to be 99.99-99.998%. |
