Embodiment 1

[0045] (1) Synthesis of vanillin n-butanol acetal

[0046] A three-necked flask was charged with 0.1 mol of vanillin, 0.3 mol of n-butanol, 0.5 g of 85% phosphoric acid, and 40 ml of n-hexane. Install the thermometer, water separator and tee joint. Add 10ml of n-hexane into the water trap to the branch pipe of the water trap, and install a serpentine reflux condenser. Vacuum with a circulating water pump and blow in nitrogen for replacement, repeat three times. The oil bath is heated to reflux, and the reaction is until no more water is formed. Cool to room temperature, add saturated potassium bicarbonate solution to neutralize, separate liquids to obtain an organic phase, add anhydrous sodium sulfate overnight, and rotatory steam to obtain a yellow viscous crude product. Add saturated sodium bisulfite solution for further purification to obtain the product. The acetal content in the crude product was 79%. After purification with saturated sodium bisulfite solution, the aceta...

Embodiment 2

[0050] (1) Vanillin 1,3-octanediol acetal

[0051] A three-necked flask was charged with 0.1 mol vanillin, 0.15 mol 1,3 octanediol, 0.5 g 85% phosphoric acid, and 40 ml n-hexane. Install the thermometer, water separator and tee joint. Add 10ml n-hexane to the water trap to the branch pipe of the water trap, and install a serpentine reflux condenser. Vacuum with a circulating water pump and blow in nitrogen for replacement, repeat three times. The oil bath is heated to reflux, and the reaction is until no more water is formed. Cool to room temperature, add saturated potassium bicarbonate solution to neutralize, separate liquids to obtain an organic phase, add anhydrous sodium sulfate overnight, and rotate to steam to obtain a yellow viscous crude product. The product is further purified by adding saturated sodium bisulfite solution. The acetal content in the crude product is 80%. After the saturated sodium bisulfite solution is purified, the acetal purity is determined to be 9...

[0055] (1) Vanillin 1,2-octanediol acetal

[0056] A three-necked flask was charged with 0.1 mol vanillin, 0.15 mol 1,2 octanediol, 0.5 g of 85% phosphoric acid, and 40 ml of n-hexane. Install the thermometer, water separator and tee joint. Add 10ml of n-hexane to the water trap to the branch pipe of the water trap, and install a serpentine reflux condenser. Vacuum with a circulating water pump and blow in nitrogen for replacement, repeat three times. The oil bath is heated to reflux, and the reaction is until no more water is formed. Cool to room temperature, add saturated potassium bicarbonate solution to neutralize, separate liquids to obtain an organic phase, add anhydrous sodium sulfate overnight, and rotate to steam to obtain a yellow viscous crude product. The product is further purified by adding saturated sodium bisulfite solution. The acetal content in the crude product was 83.4%. After purification with saturated sodium bisulfite solution, the acetal purity determi...

Abstract

The invention relates to a dissoluble vanillin based non-ionic surfactant, as well as a preparation method and an application of the dissoluble vanillin based non-ionic surfactant. A general formula of the dissoluble vanillin based non-ionic surfactant is as follows as shown in the specification. M is methyl or ethyl; R1 and R2 are C1-C20 alkyl chains; R3 and R4 are hydrogen atoms, alkyl chains or oxyalkyl chains; R is a combination of (-CH2CH2O)nR5 or (-CH2CH2O)nR5 and (-C3H6O)nR6; n is equal to 2-20; and R5 and R6 are hydrogen atoms, methyl, ethyl or propyl. The preparation method comprises the steps of preparing vanillin alkyl alcohol acetal via acetalation, and allowing acetal to react with oxirane or oxirane / epoxypropane to prepare the vanillin based non-ionic surfactant. The method is simple and easy to implement; raw materials are easy to obtain, green and nontoxic; the application performance is excellent; and the non-ionic surfactant can serve as an emolsifier, a penetrant or a wetting agent to be applied to the field of textile printing and dyeing.
