HCID 11850Galactitol

Procedure

It appeared that the fatty acid soap could be well acidified with 3-5 parts by weight of lactic acid per 100 parts by weight of reaction product. In example XXIII poorly water-soluble crystals of non-esterified dulcitol, which formed in the first water extraction, are eliminated by filtration.
