Preparations. Weigh 0.75g of impure sulfanilamide and transfer this solid to a 25mL Erlenmeyer flask.' Note the color of the impure sulfanilamide. To a second Erlenmeyer flask, add about 15mL of 95% ethyl alcohol and a boiling stone. Heat the solvent on a warm hot plate until the solvent is boiling. 2 Because 95% ethyl alcohol boils at a relatively low temperaresult in too much loss quite rapidly. Setting the temperature of the hot plate too high will Dissolving the sulf solvent through evaporation. enough hot solvent with amide. Before heating the flask containing the sulfanilamide, add containing the sulfanilemide uasteur pipet to barely cover the crystals. Then heat the flask because so little solvent is present the solvent is boiling. At first this may be difficult to see, tinue to heat the flask, and swirl. Add another small portion of solvent (about 0.5mL ), conhot plate or, for more vigorous swirl the flask frequently. You may swirl the flask while it is on the you swirl it. When you havous swirling, remove it from the hot plate for a few seconds while dissolved. If it has not, ave swirled the flask for 1015 seconds, check to see if the solid has swirling until the solvent another portion of solvent. Heat the flask again with occasional 1 The impure sulfanilamide contains 5% fluorenone, a yellow compound, as the impurity. 2 To prevent bumping in the boiling solvent, you may want to place a Pasteur pipet in the flask. Use a 50-mL flask so that the Pasteur pipet does not tip the flask over. This is a convenient method because a Pasteur pipet will also be used to transfer the solvent. -lueosed eus esennoies pue s ous of epweineins aind aul jo sojos eup asedwos kianooes a00 sod ui si4. op 01 peeu hew now Xsej ay jo wonoq aun uo pejnesas N|eidwos aney siessho Buluiezuos jexpeeq e ul xsey ous eoejd 'ounteiedwes woos te Gupnsoo si uonezileshs jeuny 'seanulw Gl-OL ueus jebuoj eq lou pinous kietejdwos senjossip plos eus gun iuen jeyplou - pyos eur enjossip of luanos yonoue isn[ ppe ol jenuesse si y jeyz elon Melejdwoo
