2,3-dihydroxypropyl acetate

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: When the reaction is performed correctly, the reaction product contains only traces of glycerol, monoacetin, diacetin and water, so that the OH number normally lies below 1. Pure triacetin can be obtained readily by distillation in a rectification column of the obtained crude product, since, at atmospheric pressure, acetic acid boils at about 118° C., acetic acid anhydride boils at about 140° C., and glyceryl triacetate (triacetin) boils at about 258° C. Any catalyst that may still be present remains in the distillation residue.

実験手順: Acetoglyceride fat mixtures are prepared using the interesterification procedure of Example 1, except that the interesterification mixture contains hydrogenated canola with both tripropionin (1.25 moles, 2.25 moles and 6 moles per mole hydrogenated canola) and triacetin (in the same proportions), the reaction temperature is 120° to 125° C., and 0.2 to 0.5% sodium methoxide is employed. Though reactions are run for about 5 to 30 minutes, most are complete in less than 10 minutes. The samples are steam deodorized after interesterification as set out in Example 1. is 120° to 125° C. most are complete in less than 10 minutes
