The benzophenone derivatives(I) are made by reacting 2,4-dihydroxybenzophenone(II) and ethyleneoxide(III) with solvent such as toluene, benzene, xylene or chloroform under a catalyst such as NaOH, KOH, Ca(OH)2, NaOMe, NaOEt, NaH, TiCl4, AlCl3, BCl3, FeCl3, SbCl3 or SnCl4 at 100-150 deg.C and 2-5 kg/cm2. The 0.1-5 mole% catalyst is used with respect to 2,4-dihydroxybenzophenone(II). The benzophenone derivatives have both lipophilicity and hydrophilicity and low volatility.
