The most important (and also the most expensive) grapefruit aroma compound is the bicyclic terpene nootkatone. It is manufactured by oxidation of valencene, which is extracted from Valencia oranges. Figure 1.23 shows two routes for this oxidation, a stoichiometric reaction using chromium trioxide, and a catalytic alternative using sodium hypochlorite (bleach) in the presence of 1 mol% osmium tetraoxide catalyst. [Pg.31]

SAFETY PROFILE An intense irritant to dssue, skin, and eyes. Flammable by chemical reaction. Ignites or explodes with heat or grinding. Explosive reaction with moisture, chromium trioxide, potassium chlorate, halocarbons (e.g., l,l-diethoxy-2-chloroethane), oxidants, sodium nitrite, air. Can become explosive in storage. Violent reaction with dinitrogen tetraoxide. Will react with water or steam to produce heat and toxic and corrosive fumes of sodium hydroxide and ammonia. When heated to decomposition it emits highly toxic fumes of NH3 and Na20. See also AMIDES. [Pg.1241]

Historically, oxidation of diacetone-a-o-glucose (1, l,2 5,6-di-0-isopropylidene-a-D-glucofuranose) was realized by ruthenium tetraoxid and various activated DMSO methods. The latter approach has found industrial application and has been reviewed. Academic laboratories still " rely mainly on chromium (VI) and ruthenium tetraoxide methods. Some of these are rather difficult to scale-up and/or require the use of toxic or expensive reagents. [Pg.276]

A study of the reaction of chromium trioxide with dicobalt tetraoxide highlights well the relative positions of the phases [JAN 97]. [Pg.528]
