Abstract
PURPOSE: To obtain the high purity title compound, useful as a reaction initiator of photosensitiue resins for printing or paint use, economically and in high yield in a short time under mild conditions, by the reaction of benzoin and an alcohol in the presence of phosgene.
CONSTITUTION: The compound of the formula is obtained by the reaction of benzoin (1 mole) and excess (10W30 mole) of the compound of the formula R- OH (R=higher alkyl, cycloalkyl), e.g. hexanol, heptanol, at low temp., preferably gradually increasing the temp. from 10W30°C to 70W90°C for 3W8hr in the presence of phosgene
