Description

Attenuated cigarette capable of making nicotine form salt and its filter tip

Technical Field

The present invention relates to cigarette, and is especially one kind of attenuated cigarette capable of makingnicotine form salt and its filter tip.

Background

It is known that cigarette smoke contains many substances harmful to human body, and the most harmful of nicotine is small amount of nicotine which can excite nerve, and excessive nicotine can raise blood pressure, accelerate heartbeat and vasoconstrictor, and also can promote platelet aggregation, and can cause hypertension, arteriosclerosis and coronary angiopathy cardiovascular diseases. And nicotine and tar in cigarette can inhibit discharge of bronchial cilia, so that waste in lung can not be discharged, and emphysema or lung cancer is caused. In order to reduce the poison of cigarette, the common method is to use acetate fiber to match with activated carbon and charcoal to make filter tip, its main defect is: because the filter material of the common filter tip adsorbs the harmful components in the smoke under the physical action, the toxic filtering effect is very limited, and the nicotine with the greatest harm cannot be effectively filtered.

An attenuating filter for salting nicotine comprises a suction end for holding the sleeve end of a cigarette for the mouth of a smoker and a middle filter section, wherein the filter section contains a hydrate of ferrous chloride or ferric chloride absorbed, impregnated or added by fibers, cotton or foam.

The concentration of the hydrate of the ferrous chloride and the ferric chloride is 0.1-100 ppm; the concentration of the hydrate of ferrous chloride-ferric chloride was 2 ppm.

The main advantages of the invention are: has the effect of effectivelyreducing nicotine toxicity.

The following further description is made in conjunction with the preferred embodiments and the accompanying drawings.

Detailed Description

Example 1

Referring to fig. 1, the cigarette 1 of the present invention comprises a tobacco shred 11 wrapped with a cigarette paper 12, with or without a filter 13 attached to one end thereof, the filter 13 being wrapped with an acetate fiber, activated carbon and charcoal, and further wrapped with a paper roll, characterized in that a double salt hydrate of ferrous chloride-ferric chloride is placed in the tobacco shred 11 and/or the filter 13, the double salt hydrate of ferrous chloride-ferric chloride having a general formula: mFeCl₂·nFeCl₃·xH₂O, wherein m, n and x are integers of 1-30 respectively. The hydration of the ferrous chloride and ferric chloride is preferredThe substance being FeCl₂·2FeCl₃·18H₂O, the double salt hydrate decomposes at 50 ℃ to release water of hydration, which dissolves in both cold and hot water.

The mechanism of salt formation between the double salt hydrate of ferrous chloride and ferric chloride and nicotine in cigarette is as follows:

firstly, after the cigarette is ignited, the flame temperature decomposes the cigarette to release the hydration water therein, and ferrous hydroxide, ferric hydroxide and hydrochloric acid are generated, and the reaction equation is as follows:

of the products after the reaction, Fe (OH)₂And Fe (OH)₃Is a weak base and HCl is a strong acid, so the whole is an acidic aqueous solution.

The nicotine generated by burning cigarette is named as nicotine, its chemical name is 1-methyl-2-pyrrolidyl pyridine, and its molecular formula is C₁₀H₁₄N₂And is weakly alkaline, and is neutralized with an acidic aqueous solution of the double salt hydrate of ferrous chloride and ferric chloride to form a salt, which is filtered by the filter tip 13 of the cigarette 1 and does not enter the body along with smoke. Of course, the double salt hydrate of ferrous chloride and ferric chloride used in the invention can also absorb harmful substances such as carbon monoxide and tar generated during burning of partial cigarettes, thereby reducing the harm of the cigarettes to human bodies.

The concentration of the double salt hydrate of ferrous chloride-ferric chloride is usually between 0.1 and 100 ppm.

The concentration of the double salt hydrate of ferrous chloride-ferric chloride is preferably 1 ppm.

In the process of making cigarettes, the method for adding the double salt hydrate of ferrous chloride and ferric chloride comprises the following steps: dissolving the double salt hydrate of ferrous chloride and ferric chloride in water to obtain an aqueous solution with the concentration of 0.1-100ppm, adding the aqueous solutioninto tobacco shreds 11 by spraying, soaking or mixing, drying by a conventional method to remove excessive water, and wrapping the tobacco shreds 11 provided with the double salt hydrate of ferrous chloride and ferric chloride with cigarette paper 12 to obtain the toxin-filtering cigarette 1 of the present invention.

Of course, the double salt hydrate of ferrous chloride and ferric chloride can be added to the filter 13 in the same manner to achieve the double filtration effect. Improving the effect of filtering poison.

The practical application proves that the cigarette 1 can not feel the burning sensation of the oral cavity and the throat and can not generate adverse reactions such as headache, dizziness, vomit, heartbeat acceleration and the like, and the concentration of nicotine in blood is reduced by 30 to 80 percent compared with a person who inhales ordinary cigarettes.

Example 2:

referring to fig. 2, in this embodiment, a filter segment 14 containing a double salt hydrate of ferrous chloride-ferric chloride is added between the tobacco thread segment 11 and the filter segment 13, and the filter comprises fibers, cotton or foam impregnated, absorbed or blended with the double salt hydrate of ferrous chloride-ferric chloride at a concentration of 0.1-100ppm, preferably 1 ppm. In fact, because there are differences in the quality and nicotine content of tobacco, the amount of the double salt hydrate added with the ferrous chloride-ferric chloride should vary with the tobacco, because too much nicotine is added to cause waste, and too little nicotine is added to prevent most of nicotine from being filtered, so in actual production, the amount of the double salt hydrate added with the ferrous chloride-ferric chloride should be calculated by testing the nicotine content in tobacco.

Example 3

Referring to fig. 3, the present invention can also be made into an attenuated cigarette filter 2 for salting nicotine, the attenuated cigarette filter 2 comprising a mouthpiece end 21 for holding the cigarette 1, a suction end 22 for a mouth of a smoker, and a filter segment 23 in between, characterized in that the filter segment 23 contains a double salt hydrate of ferrous chloride-ferric chloride absorbed, impregnated or added with fiber, cotton or foam at a concentration of 0.1-100ppm, preferably at a concentration of 2ppm, thus having a multiple effect of filtering nicotine from tobacco. Certainly, the attenuated cigarette filter 2 is matched with a common cigarette for use, and also has the effect of enabling nicotine to form salt to filter toxin.
