【摘要】 以2,6烷-基取代苯酚合成了3,5二-甲基-3′,5′-二叔丁基联苯醌(Ⅰ)和3,3′-二甲基-5,5′-二叔丁基联苯醌(Ⅱ)。适宜的合成条件是以三氯甲烷作溶剂,颗粒度低于200目的KMnO4作氧化剂,在50℃反应3 h,收率分别为90.01%和89.87%。分离提纯采用硅胶色谱柱,V(石油醚)∶V(乙酸乙酯)=60∶1的混合液作流动相,HPLC面积归一法测得Ⅰ和Ⅱ色谱纯度分别为100%和99.5%。对合成产物进行了组成和结构鉴定。用Ⅰ和Ⅱ制成有机光导器件,静电特性数据分别为Ⅰ:充电电位Vm ax=340 V,残余电势Vr=80 V,光敏性E1/2=1.60 lux.s;Ⅱ:Vm ax=840 V,Vr=160 V,E1/2=2.67 lux.s。说明化合物Ⅰ和Ⅱ有较好的静电特性。更多还原

【Abstract】 3,5-Dimethyl-3′,5′-di-tert-butyldiphenoquinone（Ⅰ） and 3,3′-dimethyl-5,5′-di-tert-butyldiphenoquinone（Ⅱ） were synthesized from 2,6-disubstituted phenols in yields of 90.01% and 89.87% respectively.Reaction was conducted at 50 ℃ in solvent chloroform for 3 h with potassium permanganate（<200 mesh） as oxidant.Separation and purification were performed in column of silica gel with pet.ether and ethyl acetate（V（pet.ether）∶V（ethyl acetate）=60∶1）as mobile phase.Then ⅠandⅡ were used for photoconductor and the data of their xerographic property were determined as follows.Ⅰ:V_max=340 V,V_r=80 V,E₁/2=1.60 lux·s;Ⅱ:V_max=840 V,V_r=160 V,E₁/2=2.67 lux·s.更多还原
