Abstract

The hydrogenation of D-fructose over different copper based skeletal and supported catalysts has been investigated. The influence of (i) the conditions of catalyst preparation, (ii) the addition of second metal, (iii) the type and amount of modifiers used and (iv) the reaction parameters on the rate of hydrogenation and the selectivity of mannitol was studied. The introduction of Co or Fe to the copper alloy increased the specific copper surface area of the Raney-copper catalysts, but decreased the selectivity of mannitol. The addition of boron and iron to the alloy resulted in a slight increase in the selectivity of mannitol. In the presence of sodium halides and sodium borate the mannitol selectivity increased over all types of skeletal catalysts. The highest selectivity of mannitol, around 88%, was obtained on supported Cu/CPG catalysts (CPG =Controlled Pore Glass). The high selectivity of mannitol of the above catalyst was attributed to the presence of boron containing surface moieties, such as B-(OH)2, in the support.
