Abstract:
1. A process for the transposition of β-pinene epoxide to myrtanal characterised in that it comprises carrying out a reaction with this epoxide in the presence of a microporous and crystalline catalyst with pores with a diameter of at least 0.52 nm that has an empirical formula in its calcinated and dehydrated form of where M is at least a metal with valence+3 selected from Al, B, Ga, Fe, Cr and combinations of these; w is a molar fraction of M with a value of between 0 and 2(x+y+z); x is a molar fraction of titanium and has a value of between 0 and 0.06; y is a molar fraction of tin and has a value of between 0 and 0.06; z is a molar fraction of zirconium and has a value of between 0 and 0.06; and where at least one of the three values “x”, “y” or “z” is different from zero.
