example 1

[0019] First select fresh mangosteen, peel and collect it, wash it with water, dry it in the air, dry it in an oven for 6 hours, grind it and sieve it to prepare 40-mesh mangosteen peel particles, and then press the solid-liquid mass ratio of 1:10 , immerse the mangosteen peel particles in absolute ethanol for 1h, and ultrasonically vibrate at 40KHz for 10min; It is adsorbed by XDA-7 macroporous resin column with an adsorption rate of 2BV / h. After the adsorption is completed, it is eluted with 2BV of distilled water, and then eluted with an ethanol solution with a mass concentration of 60%. The removal rate was 4BV / h, and then the eluate was collected and rotary evaporated to 1 / 8 of its original volume, and vacuum freeze-dried for 6 hours to prepare polyphenols from mangosteen peel; 50g of mangosteen peel polyphenols prepared above and 50mL of Add n-octylamine to 100mL of methanol, stir and mix and place in a three-necked flask, stir and react at 20°C for 20h, then cool with i...

[0022]First select fresh mangosteen, peel and collect it, wash it with water and dry it in the air, dry it in an oven for 7 hours, grind it and sieve it to prepare 45 mesh mangosteen peel particles, and then press the solid-liquid mass ratio of 1:10 , immerse the mangosteen peel particles in absolute ethanol for 1.5h, and ultrasonically vibrate at 45KHz for 12min; Adsorb it through an XDA-7 macroporous resin column with an adsorption rate of 2BV / h. After the adsorption is completed, use 2BV of distilled water for elution treatment, and then use an ethanol solution with a mass concentration of 60% for elution. The elution rate was 4.5BV / h, and then the eluate was collected and rotary evaporated to 1 / 8 of its original volume, and vacuum freeze-dried for 7 hours to prepare mangosteen peel polyphenols; 52g of mangosteen peel polyphenols prepared above and Add 52mL of n-octylamine to 105mL of methanol, stir and mix and place in a three-necked flask, stir and react at 25°C for 22h, ...

[0024] First select fresh mangosteen, peel and collect it, wash it with water, dry it, dry it in an oven for 8 hours, grind it and sieve it to prepare 50-mesh mangosteen peel particles, and then press the solid-liquid mass ratio of 1:10 , immerse the mangosteen peel particles in absolute ethanol for 2h, and ultrasonically vibrate at 50KHz for 15min; It is adsorbed by XDA-7 macroporous resin column with an adsorption rate of 2BV / h. After the adsorption is completed, it is eluted with 2BV of distilled water, and then eluted with an ethanol solution with a mass concentration of 60%. The removal rate was 5BV / h, and then the eluate was collected and rotated to 1 / 8 of its original volume, and vacuum freeze-dried for 8 hours to prepare polyphenols from mangosteen peel; 55g of mangosteen peel polyphenols prepared above and 55mL of Add n-octylamine to 110mL of methanol, stir and mix and place in a three-necked flask, stir and react at 30°C for 24h, then cool with ice water to 5°C; afte...

Abstract

The invention relates to a preparation method of a N-octyl mangosteen peel polyphenol surfactant, and belongs to the field of surfactant preparation. A phenolic surfactant which is prepared through the steps that mangosteen peels are dried in the sun and pulverized, peel powder is collected to extract peel polyphenols, and modification is conducted is provided aiming at the problems that at present, a chemical surfactant is poor in emulsifying property, low in environmental friendliness, poor in oxidation resistance of a plant surfactant and short in action time. Compared with the original plant surfactant, the duration of use of the prepared N-octyl mangosteen peel polyphenol surfactant is improved by 30%-35%, the mangosteen peels are fully used for preparation, resources are saved, and green and environmental friendliness are achieved.

Description

technical field [0001] The invention relates to a preparation method of an N-octyl mangosteen peel polyphenol surfactant, belonging to the field of surfactant preparation. Background technique [0002] Surfactants are a class of substances that can significantly reduce the surface tension of solvents and liquid-liquid interfacial tension, and have hydrophilic and lipophilic properties and special adsorption properties. Surfactants are widely used, involving all aspects of daily life and industrial production, and are known as "industrial monosodium glutamate". Surfactants are active on the surface and interface, and have extremely high ability and efficiency to reduce surface tension. Under constant temperature and constant pressure, since there is only one kind of molecule in pure liquid, its surface tension is a constant value. For a solution, since there are at least two or more molecules, its surface tension will change with the concentration of the solute. [0003] A...
