Embodiment 1

[0039] A kind of polypolyol fatty acid ester, its specific preparation steps are as follows:

[0040] Under the condition of feeding nitrogen, firstly add 300g of glycerin, 35g of trimethylolpropane, 18g of pentaerythritol and 0.4g of sodium hydroxide into the reactor, then add 8g of activated carbon and 5g of diatomaceous earth to raise the temperature to 200°C and react for 2 hours , normal pressure distillation to remove the water generated by the reaction; continue to feed nitrogen, raise the temperature to 240°C, and react for 6 hours under reduced pressure with a vacuum degree of -0.099MPa; then reduce the temperature of the material to 100°C, and turn off the vacuum , the material was filtered to obtain 300g of light yellow polyol, after testing, the hydroxyl value of this polyol was 860mgKOH / g. Then 16g octanoic acid, 10g capric acid, 10g lauric acid, 20g palmitic acid, 20g stearic acid, 124g oleic acid and 300g polypolyol are added in the reactor, then add 0.5g cataly...

Embodiment 2

[0042] A kind of polypolyol fatty acid ester, its specific preparation steps are as follows:

[0043]Under the condition of nitrogen gas, first add 210g glycerin, 105g trimethylolpropane, 35g pentaerythritol and 0.6g potassium hydroxide into the reactor, then add 10g activated clay and raise the temperature to 230°C, react for 3 hours, and distill at atmospheric pressure Remove the water generated by the reaction; continue to feed nitrogen, raise the temperature to 260°C, and react for 8 hours under reduced pressure with a vacuum degree of -0.099MPa; then reduce the temperature of the material to 100°C, turn off the vacuum, and filter the material 295 g of light yellow polyol was obtained. After testing, the hydroxyl value of the polyol was 900 mgKOH / g. Then 8g caprylic acid, 16g capric acid, 9g lauric acid, 8g palmitic acid, 9.5g stearic acid, 107g oleic acid and 295g polypolyol are added in the reactor, then add 0.7g catalyst Sn-Zn composite metal oxide, Heat up to 150°C, d...

Embodiment 3

[0045] A kind of polypolyol fatty acid ester, its specific preparation steps are as follows:

[0046] Under the condition of feeding nitrogen, firstly, 262g of glycerin, 70g of trimethylolpropane, 17.5g of pentaerythritol and 0.8g of potassium carbonate were added to the reactor, and then 12g of activated clay was added to raise the temperature to 230°C, react for 4 hours, and distill at atmospheric pressure Remove the water generated by the reaction; continue to feed nitrogen, raise the temperature to 250°C, and react for 10 hours under reduced pressure with a vacuum of -0.099MPa; then reduce the temperature of the material to 100°C, turn off the vacuum, and filter the material 298 g of light yellow polyol was obtained. After testing, the hydroxyl value of the polyol was 830 mgKOH / g. Then 9g caprylic acid, 7.6g capric acid, 6.4g lauric acid, 6.4g palmitic acid, 7.5g stearic acid, 88g oleic acid and 298g polypolyol are added to the reactor, and then 1g catalyst Sn-Zn composite...

Abstract

The invention belongs to the technical fields of oil chemistry and fine chemical engineering and discloses polyol aliphatic ester as well as a preparation method and application thereof. The polyol aliphatic ester is prepared from the following components in percentage by mass: 60%-75% of polyol and 25%-40% of C8-C18 mixed mixed fatty acid, wherein polyol is prepared from the following components in percentage by mass: 60%-85% of glycerin, 10%-30% of trimethylolpropane and 5%-10% of pentaerythritol; and C8-C18 mixed mixed fatty acid is prepared from the following components in percentage by mass: 5%-10% of caprylic acid, 5%-10% of capric acid, 5%-10% of lauric acid, 5%-10% of palmitic acid, 5%-10% of stearic acid and 50%-75% of oleic acid. The HLB value of the polyol aliphatic ester is 12-14, and the polyol aliphatic ester is a very good emulsifying agent and auxiliary thickening agent for food-grade O / W-type cosmetics.

Description

technical field [0001] The invention belongs to the fields of oleochemical technology and fine chemical technology, and specifically relates to a polypolyol fatty acid ester and its preparation method and application. Background technique [0002] Emulsifier is a substance that can improve the surface tension between the various constituent phases in the emulsion to form a uniform and stable dispersion system or emulsion. [0003] Emulsifiers are added in a relatively large amount in cream and emulsion cosmetics, generally in the range of 2.0 to 10.0%. [0004] At present, the most important emulsifiers are as follows: [0005] (1) polyacrylamide emulsifier; [0006] (2) Emulsifiers containing polyoxyethylene structure, such emulsifiers include alkylphenol polyoxyethylene ether, benzylphenol polyoxyethylene ether, styrene ethylphenol polyoxyethylene ether, fatty alcohol polyoxyethylene ether, fatty amine Polyoxyethylene ether, etc.; [0007] (3) Ester emulsifiers, such e...
