제목 Catalytic properties of HZSM-5 zeolite on synthesis of acetyl triethyl citrate by acetylation of triethyl citrate with acetic anhydride
초록 Acetyltriethylcitrate (ATEC) is an ester derived from citric acid, which can be used to replace phthalate esters as a nontoxic plasticizer. This paper presents a preparation method of ATEC by acetylation of triethylcitrate (TEC) with acetic anhydride on various acid catalysts. TEC was also prepared from citric acid monohydrate and ethanol to use as a raw material in the acetylation for the ATEC preparation. A methanesulphonic acid was employed as a homogeneous catalyst. HZSM-5 zeolites were also introduced as a heterogeneous catalyst. Catalytic activities of the acid catalysts were evaluated in comparison with yields of ATEC. The high conversion was obtained ca. 80% on HZ(75) zeolite. The yield of ATEC reached to ca. 96% on the zeolite catalyst. The mild acid strength of HZSM-5 zeolites led to high catalytic activity.
