Abstract: The alcohols are of the general formula R1R2R3C(OH), where R1 and R2 are the same or different and may be aliphatic, cycloaliphatic, araliphatic or aromatic gps. Also R2 may be H or the two R2 gps. and their neighbouring C-atom may be part of a ring or the two R2 gps. may together represent the gp. R3R3C=. The R3 gps. may be the same or different; They may be H-atoms, aliphatic, araliphatic or aromatic gps. The process involves the decomposition of the addition cpds. R1R2R3(OMgX) formed from the reaction of a carbonyl and a Grignard cpd. in ether with water or an aqueous mixture. X= halogen. The water is saturated with the ether used to dissolve the grignard cpd. The organic phase of the 2-phase mixture which forms during decomposition is heated to between 25 and 140 degrees C. Advantages lie in the process simplicity, economy, good yields and continuous operation.
