[0098] see Figure 8 and Figure 13 , in this embodiment, the polyglycerol is polyglycerol-3, and when the molar ratio of polyglycerol-3 to isostearic acid is 1:1.5-2.2, polyglycerol-3 diisostearate is obtained. Preferably, the molar ratio of polyglycerol-3 to isostearic acid is 1:1.56-2.2. The dosage of the food-grade antioxidant is 0.54%-3.25% of the sum of the mass of polyglycerol and the mass of the basic catalyst.

[0099] After the mixing reaction, the specific indicators of the obtained polyglycerol-3 diisostearate are shown in Table 3.

[0107] see Figure 9 and Figure 14 , when the polyglycerol is polyglycerol-10, and the molar ratio of polyglycerol-10 to isostearic acid is 1:1.5-2.2, polyglycerol-10 diisostearate is obtained. Preferably, the molar ratio of polyglycerol-10 to isostearic acid is 1:1.55-2.15. The dosage of the food-grade antioxidant is 0.83%-4.62% of the sum of the mass of polyglycerol and the mass of the basic catalyst.

Abstract

The invention discloses equipment for manufacturing polyglycerol isomeric fatty acid ester, and an operation method thereof. The equipment comprises a reaction kettle with stirring blades, a heating device is arranged on the outer wall of the reaction kettle, and the heating device comprises a heat-conducting spiral pipe or a heating jacket wound around the outer wall of the reaction kettle; the heat-conducting spiral pipe or the heating jacket is wound to the middle upper part of the reaction kettle from the bottom of the reaction kettle, a first heat-conducting oil inlet pipe is communicated with the lowest part of the heat-conducting spiral pipe or the heating jacket, and a second heat-conducting oil inlet pipe is communicated with the middle part of the heat-conducting spiral pipe or the heating jacket; and the heat-conducting oil outlet pipe is communicated with the highest part of the heat-conducting spiral pipe or the heating jacket. The preparation method comprises the following steps: firstly, respectively weighing polyglycerol, isostearic acid, a food-grade antioxidant and a basic catalyst in proportion, and mixing and reacting to obtain the polyglycerol isofatty acid ester. The equipment and the method have the characteristics of high yield, light color and high solid content.

Description

technical field [0001] The invention relates to a device for making polyglycerol isomeric fatty acid ester and an operation method thereof. Background technique [0002] Polyglycerol isomeric fatty acid ester is a kind of polyglycerol fatty acid ester, which does not contain PEG components and is a mild and hydrophilic emulsifier. Its chemical structure contains more hydroxyl groups, which can form hydrogen bonds with water molecules in the air and keep moisturizing for a long time. While moisturizing, it can also play a good role in emulsification, viscosity adjustment, control and adjustment of crystallization, and antibacterial. It is formed by esterification of polyglycerol and isomeric fatty acid at high temperature. Its acid and alkali resistance, high temperature resistance and emulsification stability are superior to its glyceride and other emulsifiers. [0003] Under the global environmental protection trend, the cosmetics industry will enter the era of "environmen...
