G. Fieg et al., DETERMINATION OF LIQUID-LIQUID EQUILIBRIA DATA FOR THE SYSTEM PRECUT-FATTY ALCOHOL-WATER PROPANEDIOL-1,2, Fett, 96(6), 1994, pp. 212-214
An alternative process-route for the production of fatty alcohols is t
he direct hydrogenation of triglycerides. The lately developed working
up process of the reaction mixture contains an extraction step. The s
tarting point of extended experiments were the determination of liquid
-liquid-equilibria data of the system precut-fatty alcohol/water/propa
nediol-1,2. The method used together with the results obtained is desc
ribed. A correlation shows a good agreement with the NRTL-model as wel
l as the calculation of LLE data with the UNIFAC method.
