Aldehyde conversion method using a molecular sieve and the use of the molecular sieve as a catalyst in said method

The invention relates to an aldehyde conversion method comprising putting an aldehyde into contact with oxygenated water and with a catalyst, under oxidation conditions, wherein the catalyst is a molecular sieve with pores of a diameter of at least 0.52 nm and has an empirical formula in a calcined...

Beschreibung
Zusammenfassung:The invention relates to an aldehyde conversion method comprising putting an aldehyde into contact with oxygenated water and with a catalyst, under oxidation conditions, wherein the catalyst is a molecular sieve with pores of a diameter of at least 0.52 nm and has an empirical formula in a calcined and dehydrated form of (SnxTiySi1-x-y-zGez)O2 wherein x is a molar fraction of the tin and has a value between 0.001 and 0.1; y is a molar fraction of titanium and has a value from zero to 0.1; and z is the molar fraction molar of the germanium and has a value from zero to 0.08.
