      Thanks to friend Aleks for digging this one up.

      "Conversion of rapeseed oil into ethyl esters for use as Biodiesel fuel
      involves transesterification of the oil triglycerides to mono-esters of the
      component fatty acids. To accomplish this conversion, raw rapeseed oil is
      treated at room temperature with ethyl alcohol in the presence of potassium
      hydroxide as a catalyst. During the process, the glycerol which is produced
      is insoluble in the ester product, and being heavier, settles out carrying
      most of the dissolved KOH catalyst with it. "
