Problems solved by technology

Alternatives currently being researched around the world need to meet both: the ozone depletion potential (ODP) is approximately O, the greenhouse effect potential (GWP) should be as low as possible, and the atmospheric lifetime should be as short as possible
The signing of this agreement poses a challenge to the application of the above series of hydrofluorocarbon tobacco expansion agents

Embodiment 1

[0033] The mass percentage of a kind of shredded tobacco expansion agent composition of the present embodiment is composed of: a mixture of tetrafluoropropene and chlorotrifluoropropene (the mass ratio of the two is 3:2) 70%, ethyl formate 20%, pentafluoropropene Alcohol 10%.

[0034] The preparation method is as follows: Weigh the raw materials according to the above proportions, then place them in a batching tank, stir and mix evenly, and then use a 500-mesh filter to filter under pressure to prepare the cut tobacco expander of this embodiment.

Embodiment 2

[0036] The mass percentage of a kind of shredded tobacco expansion agent composition of the present embodiment is composed of: a mixture of tetrafluoropropene, chlorotrifluoropropene and hexafluorobutene (the mass ratio of the three is 3:2:1) 70%, ethyl formate 20% ester, 10% pentafluoropropanol.

[0037] The preparation method is as follows: Weigh the raw materials according to the above mass percentage, then place them in the batching tank, stir and mix them evenly, and then pressurize and filter them with a 500-mesh filter to prepare the shredded tobacco expander of this embodiment.

Embodiment 3

[0039] The mass percentage of a kind of shredded tobacco expansion agent composition of the present embodiment is composed of: a mixture of tetrafluoropropene and chlorotrifluoropropene (the mass ratio of the two is 3:2) 70%, propyl formate 20%, pentafluoropropene Alcohol 10%.

[0040] The preparation method is as follows: Weigh the raw materials according to the above mass percentage, then place them in the batching tank, stir and mix them evenly, and then pressurize and filter them with a 500-mesh filter to prepare the shredded tobacco expander of this embodiment.

Abstract

The invention relates to a tobacco shred expanding agent. The tobacco shred expanding agent comprises the following components in percentage by mass: 49-98% of halogenated olefin; 1-50% of an ester compound; and 1-20% of halogenated ether or halogenated alcohol. The tobacco shred expanding agent provided by the invention has the advantages of the zero ODP value, the very low GWP value, the moderate boiling point, safety, low toxicity, incombustibility and volatility, and is very suitable for expanding tobacco shreds in the tobacco processing industry.

Description

technical field [0001] The invention relates to an expanding agent, in particular to a shredded tobacco expanding agent used in the tobacco processing industry. Background technique [0002] Shredded tobacco expansion technology is a new technology developed rapidly in the late 1960s and early 1970s. After the shredded tobacco is expanded, it can significantly improve the filling capacity, thereby reducing the consumption of tobacco leaves in a single box of cigarettes and reducing the amount of nicotine in the tobacco smoke. . Adding expanded shredded tobacco to cigarettes can enhance its combustion performance and reduce the tar content in cigarettes. Therefore, countries all over the world are conducting research and development on related technologies and equipment. [0003] The tobacco industry generally adopts Freon shredded tobacco expansion method, which has been banned because the CFC-11 emitted during the production process destroys the ozone layer; the carbon dio...
