Clinoptilolite의 Menthol보유성에 관한 연구 = A STUDY ON THE FIXAT10N OF MENTHOL BY CLINOPTILOLITES

다국어 초록 (Multilingual Abstract)

In this study, clinoptilolites were subjected to an array of experimental conditions, such as variations in heating temperature, reaction time, and molarity of acid and bass, and their responses measured. The activation levels were measured by adsorption indexes of toluene and ethyl alcohol and the X-ray spectra of clinoptilolites treated with acid and base. The effect of clinoptilolites on the menthol fuation was estimated by the amount of menthol produced after a given time of storage. The results were as follows: The optimum conditions for the clinoptilolites treatment were found to be IM HCI, IM NaOH, IMHCl-lM NaOH, and IM NaOH-lM HCl at $100^{\circ}C$ for 2 hours. 2. It was noted that clinoptilolites, untreated or treated with HCl, could not be used for the menthol fixation since the catalytic crating of menthol occurred with them. 3. The results from the residual menthol measurement in clinoptilolites after a specific period of storage showed that the best menthol fixation occurred in those treated with IM NaOH. 4. The menthol fuation by cigarettes with mentholated clinoptilolites was far better than that obtained by the use of mentholated tobacco column. 5. Most components in cigrettes smoke were generally reduced by the adsorption to clinoptilolites treated with IM NaOH.
