PROCEDURE

实验过程

97 g (0.2 mole) of 1,3-bis-(4-benzoyl-3-hydroxyphenoxy)-2-propanol were esterified analogously to Example 1 with 103 g (1.2 moles) of methacrylic acid. Crystallization from ethanol gave 86 g (78 percent of theory) of 1,3-bis-(4-benzoyl-3-hydroxyphenoxy)-prop-2-yl methacrylate in the form of colorless crystals having a melting point of 138° to 139° C. and a purity of 99 percent (HPLC). The UV spectrum gave two absorption maxima at wave lengths of 287 nm (extinction 0.517; extinction coefficient 28,570) and 324 nm (extinction 0.333; extinction coefficient 18,400).
