4360. To Obtain Commercial Glycerine

4360.     To Obtain Commercial Glycerine. The sweet stearine liquor of the stearine manufacturers is used for this purpose. The lime contained in it is precipitated by a stream of carbonic acid gas, or by a solution of carbonate of soda, carefully avoiding adding the latter in excess; the liquor thus obtained is then boiled a little, filtered, and evaporated to a syrupy consistence. Glycerine is also obtained from the water and washings left in the manufacture of lead or litharge plaster, by mixing them together, filtering, and submitting them to the action of a stream of sulphuretted hydrogen, which precipitates the lead; the clear liquid, after settling, is decanted, filtered, and evaporated to the consistence of syrup, in a water-bath.
