Sacarose no laboratório de química orgânica de graduação Translated title: Sucrose in undergraduate organic chemistry laboratory

Translated abstract

An experiment showing the readily available disaccharide (sucrose) as reagent for experiments in undergraduate chemistry laboratory is described. The preparation of 2,3:4,5-di-O-isopropylidene-beta-D-fructopyranose from sucrose is very simple, uses low cost materials, requires two periods of 4 hours and is useful for classroom support in undergraduate courses.
