Reaction Conditions:
with water;sodium hydroxide at 60;
Steps:
1.3 Preparation of 1-hydroxypyrene
1000 ml of water,80 g of sodium hydroxide (2 mol) and 245 g of acetoxypyrene obtained in Step 2 were added to a 2000 ml reaction flask,After the mixture is fully dissolved,The mixture was warmed to 60 ° C,After sufficient reaction (approximately 6 hours for this example)Cooling to about 30 ° C, and then dropping 500ml concentration of 35% concentrated hydrochloric acid,To be fully reacted,It will produce a large number of white solid,The mixture was filtered,dry,To give 196 g of solid 1-hydroxyprene as a white solid,The HPLC chromatogram of 1-hydroxypyrene shown in Figure 3 shows that the content of 1-hydroxypyrene is 99.28%The yield of 1-hydroxypyrene was 95.4%.
