Abstract
Crude polyglycerol fatty acid esters containing free hydroxy groups are agitated with an aqueous solution of an inorganic acid salt in order to effect separation of the glycerol and polyglycerol present. Two layers result, the upper consisting of the purified ester and the lower, an aqueous salt solution from which glycerol and polyglycerol may be recovered. A preliminary test is made at 80--100 DEG C. and using a 20 per cent aqueous solution of the salt, to ascertain whether the separation of the ester from the aqueous salt solution containing the glycerol and polyglycerol is effective. In an example, a crude ester derived from coconut oil and a polyglycerol is stirred and heated with aqueous sodium sulphate. The upper layer after separation is subjected to a further washing treatment with aqueous sodium sulphate. Sulphates of aluminium, magnesium, ammonium, zinc, lithium and potassium and sodium dihydrogenphosphate, sodium metaphosphate, sodium thiosulphate and sodium sulphite may be used satisfactorily.
