Abstract

New Pt catalysts deposited on monolayer supports containing TiO2 have been tested in the hydrogenation of α,β-unsaturated aldehydes. Enhancement of selectivity towards unsaturated alcohols has been observed in comparison to the commonly used Pt/SiO2 or Pt/TiO2 catalysts.

    The relatively lower reduction degree exhibited by less copper loaded Cu-SBA-GLY catalysts could be assigned to the existence of more isolated Cu2+ species which are more difficult to reduce than small CuO particles [72,73]. Whereas the low reduction degree exhibited by 10Cu-SBA-DP possibly results from the existence of CuOSi bonds from the precursor silicate phase which is supposed to hinder the complete reduction of Cu2+ [74]. The catalytic performance and selectivity to FFA for all the catalysts are presented in Fig. 7.

    All these forms are used in many organic syntheses in both industrial processes and research laboratories. Platinum is well-known as the catalyst of isomerization, cyclization, dehalogenation, hydrogenation and continues to be number one in hydrosilylation [1–3]. The last two reactions are particularly important.

    Subsequent hydrogenation of the CO bond of citronellal and the CC bond of geraniol and nerol yields citronellol and, thereafter, 3,7-dimethyloctanol. All these products are important perfumery chemicals, furthermore, nerol and geraniol are specially valuable because they are also used as intermediates in the synthesis of expensive fine chemicals, vitamins and polymers of special properties [1]. In the complex set of reactions involved in this process, formation of unsaturated alcohols is less favored than that of citronellal [2] but it may be improved by using metal catalysts with an adequate formulation and working under optimized experimental conditions [3,4].
