A. Sivasothy et Pj. Reilly, LOW-MOLECULAR-WEIGHT ORGANIC COMPOSITION OF ACID WATER FROM COCONUT OIL SOAPSTOCK, Journal of the American Oil Chemists' Society, 73(10), 1996, pp. 1305-1309
Soapstock from alkaline refining of coconut oil was acidified, and the
resulting acid water after neutralization was subjected to gas chroma
tography, electron-ionization and chemical-ionization mass spectroscop
y, and high-performance liquid chromatography. The chief low-molecular
weight organic components were C-4-C-18 fatty acids, hydroxylated aci
ds, and sugar alcohols. The prevalence of acids and total absence of p
hosphate compounds make coconut acid water different in composition fr
om the acid waters from other soapstocks.
