Abstract
PURPOSE: To prepare the titled mixture useful as a raw material of resins, reactive diluents, ink, paint, etc., easily, by reacting dipentaerythritol as the starting material with acrylic acid and a saturated monobasic acid.
CONSTITUTION: The objective compound of formula (R1 is acryloyl or methacryloyl; R2 is 2W6C alkanoyl; R3 is H; p, q and r are p+q+r=6, 1≤p≤6, 0≤ q≤5, and 0≤r≤3) is prepared by reacting (A) dipentaerythritol with (B) acrylic acid or methacrylic acid and (C) a 2W6C saturated monobasic acid such as acetic acid, propionic acid, butyric acid, etc. in the presence of an acid catalyst pref. sulfuric acid, p-toluenesulfonic acid, etc. The amounts of the (B) and the (C) components are pref. more than stoichiometric amounts. The water produced by the reaction is removed by the azeotropic distillation with a solvent such as n-hexane, benzene, etc.
