Embodiment 1

[0013] The preparation of embodiment 1 isononyl isononanoate (p-toluenesulfonic acid catalytic method)

[0014] Add isononanoic acid, isononanol, water-carrying agent (using cyclohexane or xylene as water-carrying agent), p-toluenesulfonic acid . Heat, stirring to dissolve the solids. After the solid dissolves, keep stirring at a constant speed. When the temperature reaches about 90°C, start to reflux and keep the reflux for 1 to 5 hours until no more water is generated and the reaction ends. Then cool to room temperature, add appropriate amount of NaHCO 3 Saturated solution (or sodium carbonate solution), standing to separate the organic layer, and then washing with water, the organic layer is distilled under reduced pressure, and the corresponding fractions are collected, which is the isononyl isononanoate compound of the present invention.

Embodiment 2

[0015] The preparation of embodiment 2 isononyl isononanoate (sulfamic acid catalytic method)

[0016] Add isononanoic acid, isononanol, water-carrying agent (cyclohexane or xylene is used as water-carrying agent) and sulfamic acid in the reactor equipped with stirrer, thermometer, reflux condenser and water separator. Heat, stirring to dissolve the solids. After the solid dissolves, keep stirring at a constant speed. When the temperature reaches about 90°C, start to reflux and keep the reflux for 1 to 5 hours until no more water is generated and the reaction ends. Then cool to room temperature, add appropriate amount of NaHCO 3 Saturated solution (or sodium carbonate solution), standing to separate the organic layer, and then washing with water, the organic layer is distilled under reduced pressure, and the corresponding fractions are collected, which is the isononyl isononanoate compound of the present invention.

Embodiment 3

[0017] The preparation of embodiment 3 isononyl isononanoate (sodium bisulfate catalyzed method)

[0018] Add isononanoic acid, isononanol, water-carrying agent (using cyclohexane or xylene as water-carrying agent) and sodium bisulfate into the reactor equipped with stirrer, thermometer, reflux condenser and water separator. Heat, stirring to dissolve the solids. After the solid dissolves, keep stirring at a constant speed. When the temperature reaches about 90°C, start to reflux and keep reflux for 1 to 5 hours until no more water is generated and the reaction ends. Then cool to room temperature, add appropriate amount of NaHCO 3 Saturated solution (or sodium carbonate solution), standing to separate the organic layer, and then washing with water, the organic layer is distilled under reduced pressure, and the corresponding fractions are collected, which is the isononyl isononanoate compound of the present invention.

Abstract

The invention discloses preparation of isononyl isononanoate and application of isononyl isononanoate in cosmetic. Isononyl isononanoate is synthesized from isononyl acid and isononyl alcohol as main raw materials with paratoluenesulfonic acid (or amidosulfonic acid or sodium hydrogen sulfate) as a catalyst by an esterification reaction method. The isononyl isononanoate compound is prepared by neutralizing reaction products with NaHCO3 saturated solution (or sodium carbonate solution), washing with water, distilling the organic layer under reduced pressure, and collecting corresponding distillate. The obtained compound is light synthetic oil; when the compound is used for skin, the compound is not oily and has good spreading property; and by using the compound, the defect that natural oil is too oily is overcome and the shortcoming that mineral oil has poor air permeability. Therefore, the compound is ideal oil for cosmetic.

Description

technical field [0001] The invention relates to the preparation of isononyl isononanoate. The compound has good skin moisturizing function and can be used as a cosmetic raw material, belonging to the technical field of ester compound synthesis in organic synthesis. Background technique [0002] Oil can form a hydrophobic film on the surface of the skin, which not only gives the skin softness, lubricity and gloss, but also prevents the invasion of external harmful substances and resists the invasion of various factors from nature to a certain extent. According to the principle of similar miscibility, oil can also dissolve oil-soluble dirt on the surface of the skin and thus be used as the main ingredient in cleaning products on the skin surface. Oil can inhibit the evaporation of water, prevent dry skin, rehydrate dry skin and hardened stratum corneum, and restore softness and elasticity to the stratum corneum. Make the skin smooth, soft and elastic, and keep the skin in a g...
