PURPOSE: To inexpensively obtain a bis(hydroxyethoxyphenyl) compound useful as a raw material of a heat resistant polymer such as a polyester by a ready reaction and an after treatment in high purity without using ethylene oxide as a raw material. CONSTITUTION: The objective compound e.g. 3,3-bis[4-(hydroxyethoxy) phenyl]phthalide} is obtained by heat reacting (A) a bisphenol compound having a cardo-type quaternary carbon expressed by formula I [R<1> and R<2> are each independently H, a halogen, etc.; Z is substantially at least one kind of a divalent substituting group selected from the group of formula II, formula III, formula IV, formula V or formula VI (R<3> -R<7> and R<10> are each independently H or a halogen; R<8> , R<9> and R<11> are each independently H, a halogen, etc.)] with (B) an ethylene carbonate in a molar ratio of (A) to (B) of (1/2)-(1/5) in the presence of a catalyst (e.g. tetrabutoxytitanium) substantially without solvent, distilling off excess ethylene carbonate from the reaction system and recrystallizing. |
