VERFAHREN ZUR HERSTELLUNG VON GEMISCHEN AUS MONO- UND OLIGOMEREN KOHLENHYDRATESTERN, DIE SO ERHAELTLICHEN KOHLENHYDRATESTERGEMISCHE UND IHRE VERWENDUNG.

摘要

Prodn. of mixts. (A) of mono- and oligomeric carbohydrate esters comprises reacting carbohydrates (I) with at least one fatty acid (or its anhydride, halide or ester) in liq. HF, serving as reaction medium and solvent, then distilling out the HF. The mixts. (A) are themselves claimed. Reaction is at -40 to 80, best 0-40, deg.C with reaction time 10 mins. 6 hr., best 1-2 hr. (not counting the time for HF distn.). The reaction mixt. contains 10-60 (25-35) wt.% (I), plus fatty acid reactant, with mole ratio 1:5-10:1.
