Abstract
AbstractA new way of controllable releasing menthol with amorphous silica is reported for the first time. Porous silica adsorbed menthol in 373‐413 K and then was covered with cellulose acetate film to form a carrier‐embedded menthol. The sealed menthol would be released at elevated temperatures once the cover fractured. Here, the influence of temperature and nature of sorbent on the adsorption of menthol along with the covering manner were investigated carefully, and the thermal release of menthol was studied with headspace gas chromatography (HS‐GC) method. Silica adsorbed about 400 mg g−1 of menthol at the optimal adsorption conditions and released most of them at about 473 K. Preliminary application in non‐combustible cigarette proven the feasibility of thermal release of menthol with the covered silica carrier.
