PURPOSE: To obtain the titled derivative, useful as a solvent for water ink, emulsifier, etc., having a cyclic acetal bonding or ketal bonding in the molecule with low viscosity and solidifying point and high boiling point and flash point.
CONSTITUTION: For example, a compound expressed by formula III is synthesized and the product is oxyalkylenated, followed by etherification or esterification, as necessary, to afford the aimed derivative expressed by formula I{B represents residue of a compound having 3W20 hydroxy groups; formula II represents acetal or ketal formed by two 1,2- or 1,3-carbon atoms with both hydroxyl and carbonyl compound R1R2C=O (R1 and R2 respectively represent H or C1W7 hydrocarbon group and R1 and R2 may link with each other to form a ring); AO represents C2W18 oxyalkylene; R represents C1W24 hydrocarbon group or acyl; a and b are 1W100; l is 1W9; m and n are 0W18; provided that 2l+m+n=3W20 and m and n are not 0 at the same time}.
