“…Krafft (188,(190)(191)(192) and others (29,30,32,45) used this procedure extensively to obtain glycerides of low molecular weight, e.g., trilaurin, trimyristin, lauromyristins, etc. The inability to distill glycerides of higher molecular weight limited the use of this procedure until recently, when interest was aroused in molecular distillations (44,62,63,77,95,180,227,272). While the latter technique enables a distillation of high molecular weight materials without decomposition, it has not proved entirely satisfactory for the fractionation of glycerides (95,227,229).…”
