| abstract | 525,473. Ether alcohols. BOHME FETTCHEMIE GES. Feb. 21, 1939, No. 5800. Convention date, Feb. 23, 1938. [Classes 2 (ii) and 2 (iii)] Ether alcohols containing one or more, preferably from one to six, alcohol and ether groups joined to an alkyl radical are prepared by subjecting the corresponding ether acids or ether esters to catalytic hydrogenation. The products may be employed as additions to washing and wetting out agents as well as to assistants for the textile, leather, furriery and paper industries and may be sulphonated to produce water soluble capillary active substances. The ether acids or ether esters are prepared by the action of alkali alcoholates or phenolates on halogen substituted acids or esters or by the action of halogen substituted hydrocarbons on acids or esters containing hydroxy group or groups, the hydrogen atom or atoms of which are substituted by an alkali metal. In examples butoxyacetic acid butyl ester is prepared from n-butanol and chloracetic acid butyl ester in the presence of sodium and hydrogenated in the presence of a copper catalyst containing iron and chromium to give butoxyethyl alcohol. Methyl-isooctylphenoxy-acetic acid ethyl ester is prepared from isooctylcresol and chloracetic acid ethyl ester and reduced to the mono-methyl-isooctyl cyclohexyl ether of ethylene glycol. Cresoxy acetic acid is prepared from cresol and chloracetic acid and reduced to methyl-cyclohexyloxyethyl alcohol. Decylbutoxyacetic acid is prepared from 2-bromo-dodecane acid-1 and sodium butylate and hydrogenated to the monobutyl ether of decylethylene glycol. An ether acid is prepared from 12-bromo-octadecane acid-1 and sodium isopropylate and hydrogenated to isopropyl ether of hexyldodecamethylene glycol. In the same way glycerine-#-dodecyl ether or hexite dodecyl ether are obtained from dodecyloxy-malonic acid diethyl ester or the dodecyl ether of mucic acid dimethyl ester. A cellulose residue substituted glycol, in some cases partly degraded, may be prepared from cellulose glycollic acid. |
