Synthesis of sucrose octaacetate by K2CO3/γ-Al2O3 was written by Yan, Xiangyang;Yang, Xinli;Liu, Jianping;Ma, Xueping. And the article was included in Henan Gongye Daxue Xuebao, Ziran Kexueban in 2008.Application of 126-14-7 This article mentions the following:
The sucrose octaacetate was prepared by esterification of acetic anhydride and sucrose with K2CO3/γ-Al2O3 as catalyst. The influencing factors on the esterification such as the reaction temperature, reaction time, the amount of catalyst and the molar ratio of sugar to diacetyl oxide were investigated. It was found that the optimal conditions were as follows: the amount of catalyst was 6.5%, reaction time was 4 h, the molar ratio of sugar to diacetyl oxide was 1:11, and the reaction temperature was 125°. Under these conditions, the yield of esterification could reach up to 92.6%. The results of test of melting and IR verified that the purity of prepared product was agreed with the American product. In the experiment, the researchers used many compounds, for example, (2R,3R,4S,5R,6R)-2-(Acetoxymethyl)-6-(((2S,3S,4R,5R)-3,4-diacetoxy-2,5-bis(acetoxymethyl)tetrahydrofuran-2-yl)oxy)tetrahydro-2H-pyran-3,4,5-triyl triacetate (cas: 126-14-7Application of 126-14-7).
(2R,3R,4S,5R,6R)-2-(Acetoxymethyl)-6-(((2S,3S,4R,5R)-3,4-diacetoxy-2,5-bis(acetoxymethyl)tetrahydrofuran-2-yl)oxy)tetrahydro-2H-pyran-3,4,5-triyl triacetate (cas: 126-14-7) belongs to tetrahydrofuran derivatives. THF (Tetrahydrofuran) is a stable compound with relatively low boiling point and excellent solvency. Tetrahydrofuran can also be produced, or synthesised, via catalytic hydrogenation of furan. This process involves converting certain sugars into THF by digesting to furfural. An alternative to this method is the catalytic hydrogenation of furan with a nickel catalyst.Application of 126-14-7
