Embodiment 1

[0023] 1. Pump 380Kg of n-butanol into the 1000L reaction kettle, stir for 30 minutes, add 40kg of vanillic alcohol, and start heating when the temperature of the kettle rises to 50-60 degrees, start adding 100kg of anhydrous sodium sulfate. Anhydrous sodium sulfate is added in four times at different temperatures, followed by: the temperature is controlled between 50-52 degrees, and 30% of the total weight of anhydrous sodium sulfate is added; the temperature is controlled between 52-54 degrees, and the total weight is added 30%; the temperature is controlled between 54-56 degrees, and 20% of the total weight is added; the temperature is controlled between 56-60 degrees, and the remaining anhydrous sodium sulfate is added, and anhydrous sodium sulfate is added each time according to the temperature rise. The time for sodium sulfate water is 10-15 hours. After the addition, the temperature is controlled between 50-55 degrees, and then the temperature is kept for 10-15 hours, an...

[0032] 1. Pump 760Kg of n-butanol into the 1000L reaction kettle, start stirring, add 80kg of vanillin alcohol, and start heating when the temperature of the kettle rises to 50-60 degrees, start adding 200kg of anhydrous sodium sulfate. Anhydrous sodium sulfate is added in four times at different temperatures, followed by: the temperature is controlled between 50-52 degrees, and 30% of the total weight of anhydrous sodium sulfate is added; the temperature is controlled between 52-54 degrees, and the total weight is added 30%; the temperature is controlled between 54-56 degrees, and 20% of the total weight is added; the temperature is controlled between 56-60 degrees, and the remaining anhydrous sodium sulfate is added, and anhydrous sodium sulfate is added each time according to the temperature rise. The time for sodium sulfate water is 10-15 hours. After the addition, the temperature is controlled between 50-55 degrees, and then the temperature is kept for 10-15 hours, and the...

Embodiment 3

[0041]1. Pump 1140Kg of n-butanol into the 3000L reaction kettle, start stirring, add 120kg of vanillin alcohol, start heating when the temperature of the kettle rises to 50-60 degrees, start adding 300kg of anhydrous sodium sulfate. Anhydrous sodium sulfate is added in four times at different temperatures, followed by: the temperature is controlled between 50-52 degrees, and 30% of the total weight of anhydrous sodium sulfate is added; the temperature is controlled between 52-54 degrees, and the total weight is added 30%; the temperature is controlled between 54-56 degrees, and 20% of the total weight is added; the temperature is controlled between 56-60 degrees, and the remaining anhydrous sodium sulfate is added, and anhydrous sodium sulfate is added each time according to the temperature rise. The time for sodium sulfate water is 10-15 hours. After the addition, the temperature is controlled between 50-55 degrees, and then the temperature is kept for 10-15 hours, and the sa...

Abstract

The invention relates to a process for producing vanillyl alcohol butyl ether. The process comprises the following steps: 1, generation of vanillyl alcohol butyl ether: extracting n-butanol, adding the n-butanol into a reaction kettle, adding vanillyl alcohol, starting carry out heating, adding 100-500 kg of anhydrous sodium sulfate in four times when the kettle temperature is increased to 50-60 DEG C, controlling the time for adding the anhydrous sodium sulfate to be 10-15 hours at each time according to the rising situation of the kettle temperature, controlling the kettle temperature to bebetween 50 DEG C and 55 DEG C after the all the anhydrous sodium sulfate is added, and then keeping the temperature for 10-15 hours, and carrying out sampling and analyzing until the reaction is completed and the vanillyl alcohol butyl ether is obtained; 2, water washing and desolvation of the vanillyl alcohol butyl ether: pumping the vanillyl alcohol butyl ether generated by the reaction in the step 1 into a desolvation kettle, carrying out washing with water, then carrying out washing with saturated saline water for twice, and carrying out standing for layering; and 3, rectification of the vanillyl alcohol butyl ether product: carrying out rectification on the vanillyl alcohol butyl ether product by using a rectification kettle, starting a vacuum pump, heating the system, controlling thetemperature to be 80-120 DEG C, and collecting the qualified product rectified out when the product containing vanillyl alcohol butyl ether is larger than or equal to 97% into a qualified product tank.

Description

technical field [0001] The invention relates to a production method of a thermosensitive agent, in particular to a process for producing vanillin butyl ether. Background technique [0002] Vanillyl butyl ether is a chemical substance with a relative molecular weight of 210.27. It is a colorless or light yellow liquid. It can penetrate into the skin surface and heat up slowly from the inside out. The thermal effect provided is that of a general pepper extract. Low irritation, mild thermal sensation, the thermal sensation lasts for several hours, and a strong thermal sensation can be obtained at a very low dosage, and it is not red, spicy, or allergic to the skin , quality and safety, can be used to prepare various cosmetics, especially in some products that express special curative effects such as breast strengthening and slimming, and are widely used in slimming products, breast strengthening products and skin care products in cosmetics , bath products, soap products, therm...
