Embodiment 1

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

[0044] (1) Preparation of 2,3:5,6-di-O-isopropylidene-α-D-mannofuranose (Ⅱ)

[0045]In a 1000mL three-neck flask, add 18g of anhydrous D-mannose (I) and 324mL of anhydrous acetone after drying, stir and mix evenly, and cool in an ice-water bath to lower the temperature of the mixture to 0°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 14°C and stirred for 7 hours. After the reaction was completed, the reaction solution was cooled in an ice-water bath to reduce the reaction solution to below 10°C, and then 33.3% aqueous sodium hydroxide solution was added dropwise to adj...

Embodiment 2

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

[0054] (1) Preparation of 2,3:5,6-di-O-isopropylidene-α-D-mannofuranose (Ⅱ)

[0055] In a 1000mL three-necked flask, add 18g of dried anhydrous D-mannose (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 10°C. Then slowly add 21.6mL 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 not exceeding 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 36°C and stirred for 3.5 hours. After the reaction was completed, the reaction solution was cooled in an ice-water bath to reduce the reaction solution to below 10°C, and then a 33.3% aqueous sodium hydroxide solution was added dropwise t...

Embodiment 3

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

[0064] (1) Preparation of 2,3:5,6-di-O-isopropylidene-α-D-mannofuranose (Ⅱ)

[0065] In a 1000mL three-necked flask, add 18g of dried anhydrous D-mannose (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 16 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 20°C and stirred for 5 hours. After the reaction was completed, the reaction solution was cooled in an ice-water bath to reduce the reaction solution to below 10°C, and then 33.3% aqueous sodium hydroxide solution was added dropwise to adjus...

Abstract

The invention relates to humectants 1-O-carboxymethyl-D-furan mannose for cigarettes and the preparation method of humectants 1-O-carboxymethyl-D-furan mannose. In the preparation method, D-mannose is used as raw material; and the protection for D-mannose hydroxide radical is carried out or removed by leading in isopropylidene. According to the preparation method, humectants 1-O-carboxymethyl-D-furan mannose for cigarettes is compounded successfully. When physical humectants performance test and sensory quality evaluation are carried out, humectants is proved to have good physical humectants performance, and can be used for reducing the irritation and miscellaneous smell of cigarettes, so that the roundness and comfortableness of the cigarettes are improved.

Description

[0001] technical field [0002] The invention belongs to the technical field of humectants, and in particular relates to a novel humectant for cigarettes, 1-O-carboxymethyl-D-mannfuranose, and a preparation method thereof. [0003] Background technique [0004] 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 [0005] The purpose of the present invention is to provide a novel polyhydroxy humectant for cigarettes—1-O-carboxymethyl-D-mannofuranose and a preparation method thereof. [0006] To achieve the above object, the present inven...
