The present invention refers to a process for the production of myrtanal from β-pinene epoxide that comprises at least of putting this epoxide in contact with a microporous and crystalline catalyst with pores of a diameter of at least 0.52 nm with an empirical formula for the calcinated and dehydrated form of Hw(MwTixSnyZrzSi1-w-x-y-z)O2 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. In the present invention, the microporous and crystalline catalyst preferably has pores of at least 0.52 nm and has a crystalline structure with an X-ray diffractogram of a zeolite beta.
