Catalytic splitting of the dimethylacetals of heptanal, 3-cyclohexylpr
opanal, 3-cyclohexylbutanal, 3-phenylpropanal and 3-phenylbutanal to c
orresponding unsaturated ethers was studied in a gas phase. Acid catal
ysts were employed in the study. Reaction conditions favorable to high
splitting selectivity to ethers were suggested. The original acetals
as well as synthesized unsaturated methylethers revealed characteristi
c odoring properties.
