| titleOfInvention | The technique that a kind of bipolar membrane electrodialysis method prepares hypophosphorous acid |
| abstract | The present invention relates to a kind of technique for preparing hypophosphorous acid using bipolar membrane electrodialysis method.Only Sodium Hypophosphite and deionized water are raw material, sodium hypophosphite solution is put into the salt room of bipolar membrane electrodialysis device, deionized water is respectively put into sour room and alkali room, and the liquid in above three compartment is pumped into bipolar membrane electrodialysis membrane stack and circulated, open bipolar membrane electrodialysis device, bipolar membrane electrodialysis is carried out, hypophosphorous acid and sodium hydroxide solution is prepared.The simple production process of the present invention for preparing hypophosphorous acid, energy consumption is low, process conditions are gentle, non-secondary pollution, and can have multigroup combo unit to repeat the membrane stack that assembling is formed between a pair of electrodes, easily carries out industrial amplification.The hypophosphorous acid being prepared can directly be used for the raw materials for production of sodium hypophosphite as product, can also be by the refined content for further reducing hypophosphorous acid sodium ion in liquor, and obtained sodium hydroxide solution is available for the pH value in regulation sodium hypophosphite production course. |
