TETRAHYDROXY-1,4-BENZOQUINONE DISODIUM SALT is used as organic synthesis intermediate and pharmaceutical intermediate, mainly used in laboratory research and development process and chemical production process. | [Synthesis]
（1)23℃After mixing 36 parts of paraldehyde with equal parts of water at ℃, transfer to a reaction kettle, and then add 12 parts of water through a separating funnel with liquid level, and 37 parts of nitric acid with a mass fraction of 63%. Slowly add to the liquid funnel, place in a 0 ° C water bath for 2 days, add 150 parts of a saturated solution of sodium bisulfite, precipitate a white precipitate, filter, wash with a small amount of alcohol, and dry to obtain glyoxal-sodium bisulfite;
（2）Weigh 7 parts of glyoxal-sodium bisulfite and 50 parts of water, heat on a water bath to make a solution, add 10 parts of saturated sodium carbonate solution, continue to heat and stir in the water bath for 0.5 h, and dissolve and pour oxygen 0.01. L / m3 to generate tetrahydroxy-p-benzoquinone disodium salt. |
