Synthesis method of 2-amino-3-hydroxypyridine

The invention discloses a synthesis method of 2-amino-3-hydroxypyridine, which comprises the following steps: reacting furfural serving as a raw material with haloid and sulfamate in an acid water solution to obtain 2-imino-3-hydroxypyridine sulfonic acid, and heating and hydrolyzing the 2-imino-3-hydroxypyridine sulfonic acid to obtain 2-amino-3-hydroxypyridine sulfate; and finally, adjusting thepH value by using alkali to obtain the 2-amino-3-hydroxypyridine. By using the method provided by the invention, the product yield is high, furfural which is cheap and easy to obtain is used as a rawmaterial, substances with higher toxicity are prevented from being used in the production process, the reaction condition is mild and no waste gas is generated in the reaction process; the solutionsof the method are all aqueous solution, and wastewater generated in the production process is a halite solution and a sulfate solution, which can be marketed as byproducts; the method reduces enterprise three-waste treatment cost, changes wastes into valuables, reduces environmental pollution from the source, reduces enterprise production cost and improves income.
