Abstract
251,890. Farbenfabriken vorm. F. Bayer & Co., and Meerwein, H. June 11, 1925. Addition to 235,584. Halogenated alcohols are produced from the corresponding halogenated aldehydes by treating a solution of the halogenated aldehyde in a primary alcohol with an alcoholate of aluminium to which aluminium chloride has been added. According to the example, a solution of butylchloral in alcohol is heated in boiling with aluminium ethylate and aluminium chloride, while nitrogen or hydrogen is passed through; after distilling off the alcohol and adding dilute sulphuric acid to the remainder, trichlorobutyl alcohol is obtained by steam distillation. Bromal and monochlorocrotonaldehyde may be similarly treated.
