Embodiment 1

[0052] This embodiment provides a system for producing natural vitamin E, and a method for producing natural vitamin E by the process system. The system for producing natural vitamin E includes a suction filtration system and a vacuum recovery system, wherein the suction filtration system includes a first suction filtration system and a second suction filtration system, such as figure 2 shown.

[0053] The first suction filtration system includes a stirring unit and a first suction filtration unit, and a refrigeration unit is also arranged between the stirring unit and the first suction filtration unit. The stirring unit in the present invention adopts the stirring tank M-100, the freezing unit adopts the medicine refrigerator M-200, and the first suction filter unit adopts the vacuum suction filter M-300. In addition, the second suction filtration system includes a reaction unit and a second suction filtration unit. The reaction unit in the present invention adopts reactor...

Embodiment 2

[0067] Select the deodorized distillate of corn germ oil, put it into the mixing tank M-100, and add the acetone-methanol mixed solution (the injection amount is monitored by the flowmeter) into it through the injection pump, the acetone and methanol in the acetone-methanol mixed solution The volume ratio is 1:4, add 4 liters of acetone methanol mixed solution per kilogram of corn germ oil deodorization distillate, then control the jacket temperature of the stirring tank at 40°C, and stir the reaction at 400rpm for 20min. After the reaction is finished, take out the mixture, transfer it to the medicine refrigerator M-200, adjust the internal temperature of the medicine refrigerator M-200 to -8°C, and make it crystallize at -8°C for 8 hours. Then take out the mixture again and place it in the vacuum filter M-300 for vacuum filtration, obtain the first filtrate, and inject it into the reactor M-400.

[0068] Utilize two injection pumps to add the ethanol of the first filtrate qu...

Embodiment 3

[0071] Select the deodorized distillate of corn germ oil, put it into the mixing tank M-100, and add the acetone-methanol mixed solution (the injection amount is monitored by the flowmeter) into it through the injection pump, the acetone and methanol in the acetone-methanol mixed solution The volume ratio is 1:3.5, add 4 liters of acetone methanol mixed solution per kilogram of corn germ oil deodorized distillate, then control the jacket temperature of the stirring tank at 45 ° C, and stir the reaction at 300 rpm for 20 min. After the reaction is finished, take out the mixture, transfer it to the medicine refrigerator M-200, adjust the internal temperature of the medicine refrigerator M-200 to -5°C, and make it crystallize at -5°C for 8 hours. Then take out the mixture again and place it in the vacuum suction filter M-300 for vacuum suction filtration, obtain the first filtrate, and inject it into the reactor M-400;

[0072] At the same time, use two injection pumps to add ethan...

Abstract

The invention discloses a method and system for producing natural vitamin E, which comprises adding a certain amount of acetone-methanol mixed solution to the deodorized distillate of corn germ oil, heating and stirring in a water bath at 40-45°C, Crystallize at -5°C for 8-10 hours, vacuum filter to obtain the first filtrate; add ethanol to the first filtrate, add sodium hydroxide solution, react at 50-55°C for 1.5-2 hours, and vacuum filter to obtain The second filtrate: adding normal hexane to the second filtrate, distilling and recovering the solvent, and the remaining product is natural vitamin E. The method and system for producing natural vitamin E invented and provided by our company has high vitamin E yield, mild and efficient reaction, and conforms to the concept of green chemistry.

Description

technical field [0001] The invention belongs to the technical field of vitamin E preparation, and in particular relates to a method and system for producing natural vitamin E. Background technique [0002] Natural vitamin E (Vitamin E) is a fat-soluble vitamin, also known as tocopherol, is one of the most important antioxidants. Soluble in organic solvents such as fat and ethanol, insoluble in water, stable to heat and acid, unstable to alkali, sensitive to oxygen, not sensitive to heat, but the activity of vitamin E is significantly reduced when fried. Tocopherol can promote the secretion of sex hormones, increase the vitality and quantity of sperm in men; increase the concentration of estrogen in women, improve fertility, prevent miscarriage, and can also be used to prevent and treat male infertility, burns, frostbite, capillary bleeding, menopausal syndrome, Beauty and other aspects have a very good curative effect. In recent years, it has also been found that vitamin E...
