Smallest reaction to be attempted, especially by newbees, is 1oz of pfed! So that even taking into account sloppiness, lack of experience and losses along the way You should get some product!
Ratios of reagents are, 3:3:1 or 1:1:1/3 ie.E:I:RP aka, equal amounts of Iodine and pfed, and a third as much RP! Comprenda!
Ok first prepare yourself an icebath! Yes icecubes and water in a sink or bucket! Now, many will say you should add this first or that first! Well after much reading of different peoples methods, I say.... Chuck the whole shebang in together, while your flask is on ice, Lift and swirl ingredients together, while maintaing on ice! Put your condenser on top and start water running thru, from bottom to top! Now, the idea is to get the reaction going in the most controlled way possible. Now you want to let reagents react in the icebath, if at all, Then move vessel from icebath to room temp, If things look like they're going too fast, put back in ice bath, You want to keep the reaction going but only at a nice slow, controlled pace! This is also necessary to control vapour in the condenser! Thick and or dis-colored smoke is bad! and plumes of smoke will escape from condenser As things progress at a nice slow pace, as things slow too much you can start applying heat! So prepare an oilbath and bring to about 50c, now if there is no more action in your vessel You can move it to the oilbath, and same as before, when things slow down, Adjust heat up, to say 100c then 150c for one hour, to make sure reaction has completed The whole time you should be watching to keep a nice reflux going, and not too much vapour is escaping from condenser!
