Process for the manufacture of ethers of hydroxy-pivalaldehyde

Ethers of the hydroxypivalaldehyde RCH2OCH2C(CH3)2CHO are prepared by a catalytic isomerization of 5,5-dimethyl-1,3-dioxans at 250 DEG to 500 DEG C. The catalyst is obtained by way of calcination from silicon dioxide, at least one element of the third main group or subgroup in the form of its oxide...

Summary:Ethers of the hydroxypivalaldehyde RCH2OCH2C(CH3)2CHO are prepared by a catalytic isomerization of 5,5-dimethyl-1,3-dioxans at 250 DEG to 500 DEG C. The catalyst is obtained by way of calcination from silicon dioxide, at least one element of the third main group or subgroup in the form of its oxide or hydroxide and at least one alkali metal oxide or hydroxide.
