Reaction Conditions:
with hydrogenchloride;sodium nitrite in water at 20; for 0.333333 h;Time;
Steps:
1 A method for synthesizing C.I. Pigment Yellow 1 by one-pot method promoted by solid particles, the steps are as follows:
10 g of polytetrafluoroethylene particles (about 70 mg/particle), 1.000 g (1 molar equivalent) of acetoacetanilide, 1.427 g (2.5 molar equivalent) of hydrochloric acid (36%), and 0.944 g (1.1 molar equivalent) were added to the reaction vessel.2-nitro-4-methylaniline, 0.448 g (1.15 molar equivalents) of sodium nitrite,10 mL of water was stirred at room temperature for 20 minutes with a modified mechanical stirring paddle (for improvement of mechanical stirring paddle: ACS Sustainable Chem. Eng. 2016, 4,6754-6762).The reaction was completed by thin-plate chromatography, filtered and rinsed with 3 mL of water, and the filter cake was dried to obtain 1.910 g of C.I.Pigment Yellow 1.The reaction mother liquor and rinse solution are reserved for the next cycle.The product yield is greater than 99%.
