Tobacco pyrolytic cracking analytical method

Abstract

Disclosed is an analysis method for tobacco thermal cracking, simulating the burning state during the cigarette smoking with different temperature areas set for low-temperature thermal purging of samples before a high-temperature cracking, and then products being introduced into a test equipment for qualitative and quantitative analysis. The invention realizes a complete simulation of the cigarette smoking process by the thermal cracking equipment, more close to the substance release state in the cigarette smoking process, facilitating a follow-up accurate detection and analysis of the tobacco and the combustion product thereof.

Description

technical field [0001] The invention belongs to the technical field of analysis and detection, and in particular relates to an analysis method for pyrolysis release products of tobacco and its products. Background technique [0002] There is a certain relationship between the chemical composition of cigarette shredded tobacco and cigarette smoke. The composition of smoke is formed by complex processes such as combustion, cracking, degradation, and distillation of shredded tobacco, among which cracking is a very important link. [0003] The pyrolysis process of cigarettes is very complicated, it is difficult to control its combustion temperature and combustion environment, and it is difficult to study and analyze. For this reason, some scholars use a pyrolyzer to crack tobacco samples, which can simulate the process of burning cigarettes. This method can easily control the conditions of cigarette thermal cracking, such as temperature, environment, etc., and because the crack...

Problems solved by technology

[0005] Problems and deficiencies in existing methods: cracking tobacco samples at instantaneous high temperature ignores that during the smoking process of cigarettes, not only combustion and high temperature cracking exist, but high temperature cracking mainly occurs in the cigarette combustion cone and its surrounding areas, and there are also chemical processes such as distillation and dry distillation. reaction

That is to say, there is a significant difference in the release of substances by simulating the combustion of cigarettes with the existing pyrolysis method
