PURPOSE:To enable economical production of the title compound having good color and smell through simple operations by reaction of an polyhydric alcohol with an alkyl glycidyl ether in the presence of a catalyst followed by neutralization, decolorization and deodorization treatments of the reaction mixture. CONSTITUTION:The reaction of a polyhydric alcohol such as pentaerythritol with an alkyl glycidyl ether such as isostearyl glycidyl ether is carried out in the presence of an acidic or basic catalyst such as sodium hydroxide in a solvent such as dimethyl sulfoxide, as they are heated at 105 deg.C for 4 hours. Then, a neutralizer such as acetic acid is added to the reaction mixture to give a mixed solution containing glyceryl-etherified polyhydric alcohol, which is subjected to decolorization treatment using an oxidizing agent such as 35% hydrogen peroxide and/or subjected to deodorizing treatment using steam, nitrogen or an inert gas whereby the objective glyceryl-etherified polyhydric alcohol of good hue and smell is economically and simply obtained. |
