By use of various chromatographic methods, it is possible to resolve some problems involved in analyzing mixtures of f a t t y amines or their surfactant derivatives, especially in the determination of chemical nature, of major constituents and the study of the nature of higher f a t t y chains. Good results are obtained with GLC using a c o h m n prepared with glass beads pretreated with KOH. Using Apiezon N one can separate amines and unsaturated polyamines. I f an oxyethylated amine is used as the stationary phase, pretreatment is not necessary. PROCIgSS FOR RECOVERING UNREACTED SUCI~OSE, F R O ~ REACTION SOLUTION O? FATTY ACID SUClgOSE ]gSTEI~. S. Mort (Dainippon
Seito Kabushiki Kaisha, Tokyo). U.S. 3,231,562. Described is a process for {he recovery of sucrose from a reaction solution containing sucrose ester, free sucrose, an alkaline catalyst and a solvent prepared by the reaction of sucrose with methyl4at~y acid esters containing 6-30 carbon atoms in the f a t t y acid moiety in the presence of a catalyst in dimethylformamide, at a temperature of 60-120C in a vacuum while, with t h e progression of the reaction, distilling out the methyl alcohol and dimethylformamide. The improvement comprises mixing the reaction solution with toluene in a quantity from between 20-95% by weight baSed on the resulting DMF-to!uene mixed solvent at a temperature of 80-85C, the amount of toluene being sufficient to render the sucrose substantially insoluble in the reaction solution, while at the same time sufficient to dissolve a substantial amount of sucrose ester, thus causing crystallization of the sucrose, cooling the mixture to about 30C and separating the sucrose from the mixture by ordinary separation methods.
