Synthetic process of 4-ampyrone product

The invention provides a synthetic process of a 4-ampyrone product, which comprises the following steps of: preparing antipyrine and sulfuric acid with concentration of 40 to 60% into solution; enabling the solution and sodium nitrite solution to simultaneously flow into a nitrosation reactor, controlling flow rates of the solution and the sodium nitrite solution, and controlling a reaction temperature to be 45 to 50 DEG C; performing a reaction with stirring; testing a reaction endpoint by iodine powder and starch test paper to regulate a water flow rate; enabling nitroso antipyrine generated by nitrosation to immediately flow into a reducing pot to react with a reducing agent ammonium hydrogen sulfite prepared in the pot and aqueous solution of ammonium sulfite; carrying out sampling and measuring a pH value and a reduction degree; heating to a temperature of 90 to 100 DEG C; after hydrolysis, cooling to a temperature of 80 to 85 DEG C; neutralizing to pH of 7 to 7.5 by liquid ammonia; carrying out standing and layering. The process provided by the invention is simple, convenient to operate and high in yield.
