Abstract
The invention discloses a preparation method of a high-softening-point rosin glycerin ester, and relates to the technical field of deep processing of chemical rosin. The method comprises the following steps: carrying out vacuum distilling and cooling on solid fumaric acid, water and rosin to obtain solid refined rosin, adding solid refined rosin to a reaction kettle to be heated to 165-175 DEG C, carrying out polymerization reaction for 3-4 hours to obtain modified rosin; and heating to 250-255 DEG C, adding glycerol and p-toluenesulfonic acid to carry out esterification reaction for 4-6 hours, so as to obtain the high-softening-point rosin glycerin ester. Compared with the prior art, the softening point of a high-softening-point rosin glycerin ester product produced by the preparation method can be up to 110-130 DEG C, so as to solve the problem that chewing gum is insufficient in chewiness because the softening point of the traditional rosin glycerin ester is low.
Description
Technical field
The present invention relates to rosin deep process technology field, especially a kind of preparation method of high-softening-point rosin glyceride.
Background technology
Chewing gum is a kind of only candy for chewing rather than eating, and its composition has matrix, sweeting agent, spices, tenderizer, pigment and functional mass.Wherein, matrix is the critical materials that chewing gum has Chewiness, mainly by rubber, resin, weighting material, cured class, emulsifying agent and antioxidant, be made, and resin the most frequently used be to take from the ester gum that pine resin liquid refines, its softening temperature of existing ester gum is at 80 ℃～90 ℃, softening temperature is on the low side, causes the chewiness of chewing gum inadequate, does not reach consumer demand.Also there is the people to reach the terpine resin of 120 ℃ with softening temperature and replace the ester gum in the chewing gum raw materials, thereby improve the chewiness of chewing gum.But because terpine resin is expensive, use the gum base materials of terpine resin as chewing gum, although improved the chewiness of chewing gum, improved greatly the production cost of chewing gum simultaneously.
Summary of the invention
The invention provides a kind of preparation method of high-softening-point rosin glyceride, solved chewing gum and caused the problem that chewing-gum chewing is inadequate because existing ester gum softening temperature is low.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:
A kind of preparation method of high-softening-point rosin glyceride comprises the following steps:
A, by rosin vacuum distilling and cooling after obtain the solid resin;
B, the solid resin obtained in 15～25 parts of solid fumaric acid, 5～10 parts of water and 70～90 parts of steps A is added in reactor and carries out polyreaction and obtain modified rosin, wherein temperature of reaction is 165 ℃～175 ℃, and the reaction times is 3～4 hours;
C, after step B polyreaction finishes, temperature of reaction kettle is warming up to 250 ℃～255 ℃, then 20～30 parts of glycerine and 0.5～1.0 part of tosic acid is carried out to esterification and obtain this high-softening-point rosin glyceride, the reaction times is 4～6 hours.
Owing to adopting technique scheme, the present invention has following beneficial effect:
The high-softening-point rosin glyceride product that the present invention produces has that softening temperature is high, cost is low, the characteristics of good stability, and while being used in the chewing gum production process using it as chewing gum base, can make chewing gum there is chewiness good the time, also reduce the production cost of chewing gum.
