An alternative procedure which is slower and gives slightly lower yields, but does not require a hydrogen chloride generator, is as follows: Three hundred grams of glycerol, 600 cc.

In a number of experiments, the glycerol used contained an appreciable amount of water.

"Dynamite" glycerol containing less than half a per cent of water is best employed; U.S. P. glycerol contains 5 per cent of water and usually gives lower yields.
