Ethyl (2,4,6-trimethylbenzoyl)phenylphosphinate Use and Manufacturing
In the reaction vessel was added 0.1mol phenylphosphinic acid and chlorobenzene 100mL, The temperature was controlled dropwise 0.11mol 2, 4, 6-trimethylbenzaldehyde, After adding at 100-120 incubated for 2 hours, Preparation of intermediates.Then cooled to room temperature, Add a small amount of hydrochloric acid to adjust the pH to 4-6, 0.13 g of vanadium diacetylacetonate was added as a catalyst, Control 5-10 dropwise 0.15mol mass percentage concentration of 35percent hydrogen peroxide, After adding at 5-10 insulation, The complete reaction of the intermediate was observed by TLC, The reaction mixture was obtained.To the reaction mixture was added 100mL of water, The pH was adjusted to neutral with saturated aqueous sodium bicarbonate solution, Separation of water layer, Washed twice with water, The excess oxidant is reduced with an appropriate amount of aqueous sodium sulfite, Separate the organic layer, Then washed twice with water, Dehydrated with anhydrous sodium sulfate dehydration, Remove the desiccant by filtration.0.11 mol of sodium hydroxide was added portionwise to the dehydrated organic layer, Control the temperature of 60-80 ° C dropwise 0.55mol diethyl sulfate, After adding insulation reaction to the end, The reaction mixture two was obtained.After the reaction mixture two with sodium hydroxide to adjust the pH to 8-10, Washed with an equal volume of water three times, Separated organic layer, After the organic layer was dried over anhydrous sodium sulfate and dehydrated, Evaporation of the organic solvent under reduced pressure gave the target (2, 4, 6-trimethylbenzoyl) phenylphosphinic acid ethyl ester, The total yield was 85.2percent based on phenylphosphinic acid and the purity was 99.6percent by HPLC.
