Abstract
The invention discloses a maleic glyceride preparing method and belongs to the technical field of rosin deep processing.The method comprises the steps of conducting vacuumizing reduced pressure distillation on 100 parts by weight of rosin serving as a raw material to obtain refined rosin, then adding 10-15 parts by weight of maleic acid, 15-20 parts by weight of glycerinum, 5-8 parts by weight of cobaltous acetate and 1-2 parts by weight of cobblestone powder with the grain size of 1-5 microns in sequence, increasing temperature to 270-280 DEG C at the pressure under a triple point, and conducting constant-temperature stirring for reaction lasting 2-4 hours; placing a reaction product into a distillation column, and increasing temperature to 200-250 DEG C in the vacuum state for distillation, so that maleic glyceride is prepared.By adding maleic acid, cobaltous acetate and cobblestone powder in the process of esterification reaction of rosin and glycerinum for modification, the anti-oxidation property of the maleic glyceride is improved.
Description
Technical field
The invention belongs to Colophonium deep process technology field, the preparation method particularly relating to a kind of Malin's acid glyceride.
Background technology
Rosin glyceride, calls as ester gum, hydrogenates ester gum and glycerol three rosin ester, in the food industry can as bodying agent material, food spice, processing aid etc. in gel-based candy.But, although rosin glyceride is widely used, but its oxidation resistent susceptibility is more weak, needs to be improved further.
Summary of the invention
The preparation method that the present invention provides a kind of Malin's acid glyceride, its Malin's acid glyceride oxidation resistent susceptibility prepared is good, thus solving the problem that tradition rosin glyceride oxidative resistance is more weak.
In order to solve above-mentioned technical problem, the technical solution adopted in the present invention is:
It includes following preparation process:
A, distillation of being reduced pressure by 100 raw material Colophonium evacuation obtain resin；
B, under stirring, the resin that step A prepares is put in reactor, and it is sequentially added into 10 weight portion～15 weight portion maleic acids, 15 weight portion～20 parts by weight of glycerin, 5 weight portion～8 weight portion cobalt acetates and cobblestone powder that 1 weight portion～2 weight portion particle diameter is 1 micron～5 microns, then under three phase point pressure below, heating is to 270 DEG C～280 DEG C, and constant temperature stirs, reacts 2 hours～4 hours；
C, the material that step B prepares is put into distillation column, and under vacuum conditions, distill when heating is to 200 DEG C～250 DEG C, prepare Malin's acid glyceride.
Owing to adopting technique scheme, there is advantages that
The present invention is modified by first being undertaken Colophonium and glycerol adding maleic acid, acid cobalt and cobblestone powder in the process of esterification, thus enhancing the oxidation resistent susceptibility of product Malin's acid glyceride.
