Five Kinds Of Tobacco Additives In The Pyrolysis Behavior And Flue Gas Composition Analysis

The low tar flue-cured tobacco cigarette fragrance compensation technology is one of cigarette manufacturing industry core technologies.Falls thorough along with the Chinese type cigarette which Jiao Jianhai works, carries on the fragrance compensation through the spice to hold the important status.The cigarette adds the fragrant feeding to improve with the stable cigarette suction quality, the establishment cigarette style has the important influence.The paper uses the online thermal crack to vent spleen the chromatograph/mass spectrum association with the technology to 5 kind of smoke with the chemical additive (alpha-ionone, fragrant phytol, original catecha aldehyde and Chinese native medicine chemical additive BS-08, H/B-63113) simulates cigarette burning the hot decomposition process.Has conducted the decomposition behavior research to the first three kind of chemical additive monomer, the increase smoke type hot daughter product and the haze ingredient has conducted the component contrast analysis research, explored the cigarette to add in the fragrance the monomer increase spice before and after cigarette burning chemical composition change quantity.Obtains after the research:(1) The decomposition experiment examines the result to demonstrate that, alpha-the ionone, the fragrant phytol, the original catecha aldehyde three kind of isolated perfumes majority of send the fragrant material in 800℃below to produce.(2) In 300-900℃, in various chemical additives daughter product deleterious substance comparative content, the biggest release quantity is in 900℃; Also reduces its accumulation release quantity rapid reduction along with the decomposition temperature.(3) The smoke type thermal crack unraveling fruit indicated that,In haze smoke alkali biggest release quantity in 600℃.By the empirical datum inference, reduces the thermal crack solution temperature, may cause the daughter product the deleterious substance large scale reduction, may provide the reference for the low harm cigarette design.(4) In the chemical additive main daughter product and the haze ingredient is same, indicated obtains the data according to the temperature program decomposition analysis, has the similarity with the cigarette burning situation, the hot decomposition may very good simulation cigarette burning.
