| titleOfInvention | Salifying device for producing 2-hydroxy-3-naphthoic acid |
| abstract | The utility model discloses a salify device that production 2-hydroxy-3-naphthoic acid was used, this salify device includes liquid caustic soda storage tank, 2-naphthol metering tank, salify reation kettle, liquid caustic soda heating tank, is used for all holding and the liquid caustic soda quantitative groove of the liquid caustic soda of arranging fixed volume outward at every turn, and liquid caustic soda storage tank, liquid caustic soda heating tank, liquid caustic soda quantitative groove and salify reation kettle communicate in proper order, and 2-naphthol metering tank communicates with salify reation kettle; the liquid caustic soda quantitative tank comprises a tank body and an overflow port formed in the upper part of the tank body, the overflow port is communicated with a liquid caustic soda storage tank, the bottom of the tank body comprises a conical chassis protruding downwards, a discharge port is formed in the conical chassis, and the discharge port is communicated with the upper part of the salt-forming reaction kettle; the salifying device can overcome the problem of inaccurate liquid caustic soda adding proportion in the existing salifying process, realizes quantitative and accurate feeding, and further improves the salifying reaction yield. |
