PREPARATION OF ALDEHYDE ETHERS

摘要

Preparation of aldehyde-ethers of formula (1) comprises hydroformylating compds. of formula(4) with hydrogen and carbon monoxide in a hydroformylating catalyst contg. 8 series metals at 30-160≦̸C and 0.2-300 kg/cm2 absolute. R1 and R2=different C1-4 alkyl, R3 and R4=different H or C1-3 alkyl. Alternatively R1=C1-4 alkyl, R2 and R3 form 5-ring or 6-ring cycloaliphatic with their own carbon atoms of R2 and R3, R4= H or C1-3 alkyl, and Y= -CH2-CH2-CH2 or-CH2-CH(CH3)-.
