Embodiment 1

[0036] This embodiment discloses the preparation method of formula II compound inositol hexastearate of the present invention, and its reaction formula is

[0037]

[0038] The specific operation is as follows:

[0039] Take 30g of inositol, 284g of stearic acid, 1.6g of tin powder, and 60mL of xylene in a 500mL three-necked flask. The reaction device is equipped with a thermometer, electromagnetic stirring, oil bath, and reflux water separator.

[0040] Heat until reflux occurs, continuously separate the generated water until no water is formed, then cool until there is no reflux, add 3g activated clay and continue stirring for 1 hour, then filter under reduced pressure, recover xylene, cool, crush, and dry to obtain white 295 g of phytate in the form of waxy powder (yield>99%).

[0041] In the prior art, the industrial preparation process of higher fatty acid esters is generally carried out by polyhydric alcohol and higher fatty acid in the presence of a catalyst and a w...

Abstract

The invention discloses an inositol fatty acid ester as well as a preparation method and application thereof, belongs to the field of plastic processing and solves the problems that in the prior art,pentaerythritol testearate cannot meet the injection molding processing performance of engineering plastics, the yield of pentaerythritol hexastearate is low, and the cost of the pentaerythritol hexastearate is high. The inositol fatty acid ester disclosed by the invention has a formula I shown in the description, in the formula, R is selected from hydrogen or stearic acid residues. The inventionfurther discloses a preparation method of the inositol fatty acid ester. The preparation method comprises the following step: performing an esterification reaction on inositol and stearic acid under the action of a catalyst, so as to obtain the inositol fatty acid ester. The invention further discloses application of the inositol fatty acid ester in preparing plastic processing aids. The inositolfatty acid ester disclosed by the invention has excellent internal and external lubricity and can significantly improve the injection molding processing performance of engineering plastics.

Description

technical field [0001] The invention belongs to the field of plastic processing, and in particular relates to an inositol fatty acid ester and a preparation method and application thereof. Background technique [0002] During the processing of thermoplastics, the resin polymer usually has a high viscosity after melting. When the molten polymer passes through the gate, slit and other runners, the polymer melt must produce friction with the surface of the processing machine. There is also friction between the polymers due to relative motion. These frictions hinder the flow of the melt. At the same time, severe friction makes the surface of the plastic product rough, lacking luster or flowing lines. In order to alleviate or overcome the adverse effects caused by such friction, it is necessary to add an additive that reduces the interfacial viscosity performance——lubricant. Adding lubricants to thermoplastic resins can improve melt fluidity, reduce injection resistance or extru...
