Production of solutions of alkali metal salts (I) of functionalized alcohols (II) in a solvent mixture including (II), by reacting (II) with an alkali metal alkoxide or hydroxide (III), comprises distilling off part of the released alkanol or water without adding an entrainer and then distilling off the rest using another organic solvent as entrainer. Production of solutions of alkali metal salts of formula MOYXR1 (I) by reacting a functionalized alcohol of formula HOYXR1 (II) with an alkali metal alkoxide or hydroxide of formula MOR2 (III) to form a solution of (I) in a solvent mixture including (II), comprises distilling off part of the released alkanol or water without adding an entrainer and then distilling off the rest using another organic solvent as entrainer. M = Li, Na, K, Rb or Cs; Y = 1-8C alkylene; X = O, S or NR1; R1 = H, 1-8C alkyl, 2-8C alkenyl, 2-8C alkynyl, 3-8C cycloalkyl, 6-18C aryl, 7-19C aralkyl, 3-18C heteroaryl or 4-19C heteroaralkyl, where cycloalkyl, aryl and heteroaryl are optionally substituted by 1-3 of 1-8C alkyl; and R2 = H, Me, Et, Pr, i-Pr, s-Bu, i-Bu or t-Bu.
