摘要
利用脉冲激光光声微量量热技术测定出二特丁基过氧化物［（ｔ＿ＢｕＯ）２］光解量子产率Φ，及（ｔ＿ＢｕＯ）２与５种氯代酚光化夺氢反应过程的热效应，并结合热力学计算出了５种氯代酚中的Ｏ—Ｈ键解离能。
The quantum yield ( Φ ) for photolysis of ( t _BuO) 2 and heat effects in the abstraction reaction of hydrogen for ( t _BuO) 2 with five Cl n C 6H 5- n OH were determined by pulsed laser photoacoustic calorimetry technique. By combination of those results with literature data for the heats of formation of t _BuOH, ( t _BuO) 2 and H, the dissociation bond energies of O—H in Cl n C 6H 5- n OH were calculated.
