    摘要: The invention relates to a process for the preparation of a 1-alkyl glycerol ether of the formula (I)

    in which
    (a) an alkyl glycidyl ether of the formula (II)

    in which R is an unbranched or branched C 1 - to C 24 -alkyl group, where the alkyl group may be substituted with one or more hydroxy and/or C 1 - to C 4 -alkoxy group(s) and/or the alkyl chain may be interrupted by up to four oxygen atoms,
    is added to
    (x) a carboxylic acid having 1 to 10 carbon atoms,
    (y) an ester of a carboxylic acid having 1 to 10 carbon atoms and/or
    (z) an anhydride of a carboxylic acid having 1 to 10 carbon atoms

    and the low-water reaction mixture containing a catalytic amount of a strong acid is reacted at a temperature of more than 40°C to give an acylated alkyl glycerol ether, and
    (b) the acylated alkyl glycerol ether is reacted in order to obtain the alkyl glycerol ether of the formula (I).
