Embodiment 1

[0043] A preparation method of a novel humectant for cigarettes, comprising the steps of:

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

[0045]In a 1000mL three-neck flask, add 18g of dried D-galactose (I) and 360mL of anhydrous acetone, stir and mix evenly, and cool in an ice-water bath to lower the temperature of the mixture to 10°C. Then slowly add 9mL of concentrated sulfuric acid dropwise, control the rate of addition to prevent the reaction system from heating up too fast and cause side reactions, and keep the temperature below 10°C during the dropwise addition. After the concentrated sulfuric acid was added dropwise, the ice-water bath was removed, and the temperature was raised to about 15°C and stirred for 4 hours. After cooling in an ice-water bath to lower the reaction solution below 5 °C, 33.3% aqueous sodium hydroxide solution was added dropwise to adjust the pH of the reaction solution to 7. Subsequently, the reaction solution...

Embodiment 2

[0053] A preparation method of a novel humectant for cigarettes, comprising the steps of:

[0054] (1) Preparation of 1,2:3,4-di-O-isopropylidene-α-D-galactopyranose (Ⅱ)

[0055] In a 1000mL three-necked flask, add 18g of dried D-galactose (I) and 540mL of anhydrous acetone, stir and mix evenly, and cool in an ice-water bath to lower the temperature of the mixture to 5°C. Then slowly add 18mL of concentrated sulfuric acid dropwise, control the drop rate to prevent the reaction system from heating up too fast and cause side reactions, and keep the temperature below 10°C during the dropwise addition. After the concentrated sulfuric acid was added dropwise, the ice-water bath was removed, and the temperature was raised to about 35°C and stirred for 8 hours. After cooling in an ice-water bath to lower the reaction solution below 5°C, 33.3% aqueous sodium hydroxide solution was added dropwise to adjust the pH of the reaction solution to 8. Subsequently, the reaction solution was ...

Embodiment 3

[0063] A preparation method of a novel humectant for cigarettes, comprising the steps of:

[0064] (1) Preparation of 1,2:3,4-di-O-isopropylidene-α-D-galactopyranose (Ⅱ)

[0065] In a 1000mL three-necked flask, add 18g of dried D-galactose (I) and 400mL of anhydrous acetone, stir and mix evenly, and cool in an ice-water bath to lower the temperature of the mixture to 5°C. Then slowly add 12 mL of concentrated sulfuric acid dropwise, control the rate of addition to prevent the reaction system from heating up too fast and cause side reactions, and keep the temperature below 10°C during the dropwise addition. After the concentrated sulfuric acid was added dropwise, the ice-water bath was removed, and the temperature was raised to about 25°C and stirred for 6 hours. After cooling in an ice-water bath to lower the reaction solution below 5 °C, 33.3% aqueous sodium hydroxide solution was added dropwise to adjust the pH of the reaction solution to 7.5. Subsequently, the reaction so...

Abstract

The invention relates to novel humectant, namely 6-O-carboxymethyl-D-galactopyranose for tobacco and a preparation method of the humectant. D-galactose is used as material; isopropylidene is led to carry out protection and deprotection on the D-galactose hydroxyl, and the novel polyhydroxy humectant, namely 6-O-carboxymethyl-D-galactopyranose for tobacco is successfully synthetized. The humectant has good physical moisturizing action on a cigarette by physical moisturizing performance test and inner sense quality evaluation, irritation and miscellaneous gas of the cigarette can be reduced, and the round taste and comfort of cigarette smoke are improved.

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 6-O-carboxymethyl-D-galactopyranose. 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 novel polyhydroxy humectant for cigarettes—6-O-carboxymethyl-D-galactose and a preparation method thereof. [0004] To achieve the above object, the...
