Embodiment 1

[0043] A method for preparing a humectant for tobacco (1-O-carboxymethyl-D-fructofuranose), comprising the steps of:

[0044] (1) Preparation of 1,2:3,4-di-O-isopropylidene-α-D-fructopyranose (Ⅱ)

[0045] In a 500mL three-neck flask equipped with a magnetic stirring device, a thermometer and a reflux condenser, add 240mL of dried acetone, cool in an ice-water bath to lower the temperature to about 5°C, add 12g of anhydrous D-fructose under stirring, and then Slowly add 6 mL of concentrated sulfuric acid dropwise, keeping the temperature below 10°C during the dropwise addition. After the dropwise addition, the ice-water bath was removed, and the temperature was naturally raised to 15° C. and stirred for 1 h.

[0046]After the reaction was completed, 33.3% aqueous sodium hydroxide solution was added dropwise to adjust the pH value of the reaction solution to 7. Subsequently, the reaction liquid was concentrated under reduced pressure to make the volume to about 50 mL (unreacte...

Embodiment 2

[0055] A preparation method of a novel humectant for cigarettes, comprising the steps of:

[0056] (1) Preparation of 1,2:3,4-di-O-isopropylidene-α-D-fructopyranose (Ⅱ)

[0057] In a 1000mL three-necked flask equipped with a magnetic stirring device, a thermometer and a reflux condenser, add 360mL of dried acetone, cool in an ice-water bath to lower the temperature to about 5°C, add 12g of anhydrous D-fructose under stirring, and then Slowly add 12 mL of concentrated sulfuric acid dropwise, keeping the temperature below 10°C during the dropwise addition. After the dropwise addition was completed, the ice-water bath was removed, and the temperature was raised to 35° C. and the reaction was stirred for 1 h.

[0058] After the reaction was completed, 33.3% aqueous sodium hydroxide solution was added dropwise to adjust the pH value of the reaction solution to 8. Subsequently, the reaction solution was concentrated under reduced pressure to a volume of about 50 mL (unreacted acet...

Embodiment 3

[0067] A preparation method of a novel humectant for cigarettes, comprising the steps of:

[0068] (1) Preparation of 1,2:3,4-di-O-isopropylidene-α-D-fructopyranose (Ⅱ)

[0069] In a 1000mL three-necked flask equipped with a magnetic stirring device, a thermometer and a reflux condenser, add 280mL of dried acetone, cool in an ice-water bath to lower the solution temperature to about 5°C, add 12g of anhydrous D-fructose under stirring, Then slowly add 8 mL of concentrated sulfuric acid dropwise, keeping the temperature below 10°C during the dropwise addition. After the dropwise addition, the ice-water bath was removed, and the temperature was raised to 25° C. and the reaction was stirred for 1.5 h.

[0070] After the reaction, 33.3% aqueous sodium hydroxide solution was added dropwise to adjust the pH of the reaction solution to 7.5. Subsequently, the reaction liquid was concentrated under reduced pressure to make the volume to about 50 mL (unreacted acetone was removed), the...

Abstract

The invention relates to a humectant 1-O-carboxymethyl-D-fructofuranose for cigarettes and a preparation method thereof. D-levulose is used as the raw material, and isopropylidene group is introduced to protect and deprotect the hydroxy group of the D-levulose, thereby successfully synthesizing the polyhydroxy humectant 1-O-carboxymethyl-D-fructofuranose for cigarettes. The physical humidification performance test and inherent esthetic quality evaluation detect that the humectant has a favorable humidifying action on cigarettes, can reduce irritation and impure gas of the cigarettes, and can enhance the smoothness and comfort of the cigarette smoke.

Description

technical field [0001] The invention belongs to the technical field of humectants, and in particular relates to a novel humectant for cigarettes and a preparation method thereof. The humectant for cigarettes is 1-O-carboxymethyl-D-fructofuranose. Background technique [0002] At present, glycerin, propylene glycol, sorbitol and other polyhydroxy substances are mainly used as humectants in my country’s cigarette industry. The main function of using such humectants is to maintain the moisture content of shredded tobacco during processing and improve the processing resistance of shredded tobacco. The above-mentioned humectant has unsatisfactory effects on maintaining the moisture content of finished cigarettes and improving smoking comfort. Contents of the invention [0003] The purpose of the present invention is to provide a humectant for cigarettes—1-O-carboxymethyl-D-fructofuranose and a preparation method thereof. [0004] To achieve the above object, the present inven...
