WebThe ketalization of glycerol with ketones generates branched oxygenates, solketal (2,2-dimethyl-[1,3] dioxan-4-yl methanol), and 2,2-dimethyl [1,3] dioxane-5-ol; however, when the reaction is carried out with acetone, the selectivity is higher for the solketal molecule, which has a five-membered ring [5]. Web23 jun. 2024 · Ca–Zr–Sn composite oxides catalysts for 1,4-butanediol (BDO) selective dehydration to 3-butene-1-ol (BTO) are synthesized by impregnation and co-precipitation in the present work. The results show that Ca–Zr–Sn catalysts prepared from co-precipitation by using NaOH-Na2CO3 mixing alkali solution as precipitant exhibit an excellent catalytic … branching programming structure
