Embodiment 1

[0076] As shown in Figure 1, utilize 40% sulfuric acid aqueous solution and acetone / glacial acetic acid / acetonitrile / ethyl acetate / pyridine / dimethyl sulfoxide successively to identify diacetate fiber tow for tobacco:

[0077] In the first step, according to the test procedure of the solvent identification method described in Test 1, 40% sulfuric acid aqueous solution is used as a solvent, and according to the dissolution phenomenon of the sample at room temperature, nylon 6, nylon 66 or tobacco diacetate fiber tow Separated from other fiber tows. The samples that were completely dissolved in 40% sulfuric acid aqueous solution were nylon 6, nylon 66, and diacetate fiber tow for cigarettes.

[0078] The second step is to retake the sample completely dissolved in 40% sulfuric acid aqueous solution, use acetone / glacial acetic acid / acetonitrile / ethyl acetate / pyridine / dimethyl sulfoxide as solvent, according to the dissolution phenomenon of the sample at normal temperature, put Nyl...

Embodiment 2

[0080] Use dimethyl sulfoxide and 40% sulfuric acid aqueous solution to identify diacetate fiber tow for cigarettes in turn:

[0081] The first step, according to the test program of the solvent identification method described in Example 1, use dimethyl sulfoxide as a solvent, according to the dissolution phenomenon of the sample at normal temperature, diacetate fiber tow, polyacrylonitrile fiber tow Tow, polyvinyl formal fiber tow, polyvinyl chloride fiber tow, polyurethane fiber tow, triacetate fiber tow, diacetate fiber tow for cigarettes and other fiber tows. The samples completely dissolved in dimethyl sulfoxide are diacetate fiber tow, polyacrylonitrile fiber tow, polyvinyl formal fiber tow, polyvinyl chloride fiber tow, polyurethane fiber tow , Triacetate fiber tow, diacetate fiber tow for tobacco.

[0082] In the second step, use 40% sulfuric acid aqueous solution as the solvent for the sample completely dissolved in dimethyl sulfoxide, and according to the dissolutio...

Embodiment 3

[0084] Use ethyl acetate and 40% sulfuric acid aqueous solution to identify diacetate fiber tow for cigarettes in turn:

[0085] The first step, according to the test program of the solvent identification method described in Example 1, use ethyl acetate as a solvent, according to the dissolution phenomenon of the sample at normal temperature, diacetate fiber tow, polystyrene fiber tow , Diacetate cellulose tow for tobacco is distinguished from other fiber tows. The samples that were completely dissolved in ethyl acetate were diacetate fiber tow, polystyrene fiber tow, and diacetate fiber tow for tobacco.

[0086] In the second step, use 40% sulfuric acid aqueous solution as the solvent for the sample completely dissolved in ethyl acetate. According to the dissolution phenomenon of the sample at normal temperature, diacetate fiber tow, polystyrene fiber tow, cigarette Diacetate tow is distinguished. The sample dissolved in 40% sulfuric acid aqueous solution is diacetate fiber...

Abstract

The invention discloses a solvent identification method for cigarette tows. The solvent identification method is characterized in that diacetate fiber cigarette tows and polypropylene fiber cigarette tows can be distinguished from other common fiber tows by using different solvents according to a specific sequence, so as to identify the authenticity of a cigarette filter stick (filter tip) material. The identification method disclosed by the invention is simple, convenient and accurate and can be used for monitoring cigarette proprietary products including the cigarette tows, the cigarette filter stick (filter tip) and the like in a tobacco industry; the solvent identification method is of great guiding significance to identification of the authenticity of the cigarettes, as well as penalty measurement and the like of behaviors of smuggling and illegally operation of proprietary products of the cigarette tows and the filter sticks.

Description

technical field [0001] The invention belongs to the technical field of identification and detection of auxiliary materials for cigarettes, and in particular relates to a solvent identification method for diacetate fiber tows for cigarettes and polypropylene fiber tows for cigarettes. technical background [0002] Diacetate fiber tow for cigarettes and polypropylene fiber tow for cigarettes are important auxiliary materials for producing cigarettes. The main raw materials are tobacco tow and filter rod forming paper, which are processed, rolled and cut to make filter rods. The filter rod is connected with the cigarette branch through the tipping paper to form the suction end of the cigarette, which is called the filter tip. Cigarette tow and filter (tip) rods belong to tobacco monopoly products. In view of factors such as retention efficiency of harmful components in smoke and safety and health indicators, currently only cellulose acetate tow filter sticks (filter tips) and...
