Reaction Conditions:

with iron(III) chloride;sodium hydroxide in water at 130; for 2 h;Inert atmosphere;Reagent/catalyst;Temperature;

Steps:

5-1; 5-2; 6-c Third Step (Dehydrochiorination of1,1,1 ,2,3,3-Hexachloropropane (230da))

A 100-mL three-necked flask equipped with a ball filter, a thermometer, a Dimroth condenser that allows tap water to flow therethrough, and a stirrer was charged with 58.62 g (0.23 mol) of 1,1,1,2,3,3-hexachloropropane (230da) having a purity of 96.2 FID% and 0.9 g (0.006 mol) of ferric chloride, and then stirring was started. It was connected by using a PFA tube at an upper part of the Dimroth condenser to an empty trap of a 500-mL PFA container and then a 500-mL PFA container charged with 250 g of sodium hydroxide aqueous solution having a concentration of 25 weight %. Herein, hydrogen chloride gas produced as a by-product was trapped. 93.1 FID %, and other impurities were 5.6 FID % (see Table5).
