Yield:4264-83-9 297 g

Reaction Conditions:

with sodium hydroxide in water at 0;Cooling with ice;

Steps:

1.4; 2.4 (IV) Synthesis of disodium p-nitrophenyl phosphate
The off-white solid was dissolved in deionized water, and the temperature was lowered to 0 ° C in an ice water bath. A 12N sodium hydroxide solution was added dropwise, and the pH value of the reaction solution system was monitored by a pH meter. After concentrating the reaction solution, a yellow solid was obtained. The crude product was recrystallized from acetone / water (5: 1) to obtain 297 g of a white to pale yellow solid.The total yield of the four steps is 80%.
