Procedure

Into a 1 liter reaction flask equipped with heating mantle, stirrer, thermometer and reflux condenser are placed 172 grams of cyclopentanol; 265 grams of 3-mercaptopropionic acid and 0.5 grams of paratoluene sulfonic acid. The reaction mass is heated to reflux and reflux is continued for a period of 8 hours. At the end of the 8 hour period, the reaction mass is fractionally distilled on a 2" splash column yielding the following fractions:
