Description

technical field [0001] The invention belongs to the technical field of analytical chemistry, and in particular relates to a method for detecting 1,3-butadiene in hot melt adhesives. Background technique [0002] 1,3-Butadiene is a colorless gas with a faint aromatic odor, which is highly irritating to the skin and mucous membranes, and has an anesthetic effect at high concentrations. [0003] As one of the smoking materials, hot melt adhesives are used in cigarette filter rods and packaging boxes, and may have direct contact with consumers. Although the proportion of hot melt adhesive in the composition of cigarette materials is relatively small, considering that it may contain pollutant residues, and its use in the cigarette production process requires a heating process (130 ℃ ~ 160 ℃), it is easy to cause The volatilization of volatile substances (such as 1,3-butadiene) causes pollution to the environment and other smoking materials and finished cigarettes. detection met...
