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. |
