Module 3 Picric Acid From Phenol Youtube

Module 3 Picric Acid From Phenol Youtube In this module the preparation of picric acid through nitration is discussed. Picric acid is 2,4,6trinitrophenoli synthesised it from phenol. you can also try synthesis from aspirini first sulfonated phenol and then i nitrated itphenol.

To Prepare And Submit Picric Acid From Phenol Organic Chemistry B Pharmaceutical organic chemistry ii b.pharm 2nd yr 3rd semester. 1. weigh 4 g of phenol (or take 5.0 ml of liquefied phenol) and place in a 500 ml bottom flask. 2. add 5.0 ml con. sulphuric acid and mix thoroughly. as their action is exothermic, the mixture becomes warm. 3. heat the flask in a water bath for 30 minutes to complete the formation of phenol sulphonic acid. Wait two minutes, then cool down the mixture. add enough water to nearly fill the test tube (about 20 20 ml). the picric acid is an oil, that soon gets solid after one minute or two. throw the liquid away. half fill the tube with 10 ml 10 m l water. heat to 100 ∘c 100 ∘ c : the picric acid gets dissolved. Picric acid (pa, c 6 h 3 n 3 o 7 ) has been synthesized according to literature, 29 and recrystallized from hot water to get the appropriate particle sizes. 3,4 dinitro 1h pyrazole (3,4 dnp, c 3 h.

Picric acid (pa, c 6 h 3 n 3 o 7 ) has been synthesized according to literature, 29 and recrystallized from hot water to get the appropriate particle sizes. 3,4 dinitro 1h pyrazole (3,4 dnp, c 3 h. Q 3. nowadays picric acid is prepared by treating phonel first with concentrated sulphuric acid which converts is to phenol 2, 4 disulphonoc acid, and then with concentrated nitric acid to get 2,4,6 trinitrophenol. Picric acid (2,4,6 trinitrophenol). safety warning: picric acid (2,4,6 trinitrophenol) is an explosive and may explode from heating, flame, friction or shocking. adding concen trated nitric acid to a solution of phenol in dmso is very exothermic and the mixture may boil over. therefore, the nitric acid should be added dropwise with careful cooling.
