Nucleophilic Substitution Reaction on the Porphyrin Ring: 2. The Solvent Effect in the Reaction of 2-NO_2-TPPCu(ⅱ) with Sodium Phenoxide 卟啉环上的亲核取代:2.溶剂对2-NO2-TPPCu(Ⅱ)与苯酚钠反应的影响
The concentration of active centers ( [ P~]) in cyclohexene oxide polymerization was determined by using sodium phenoxide as terminating agent. It was found that [ P~] increased linearly during the early stage of polymerization; 用苯酚钠终止氧化环已烯光聚合中的活性中心,从而测得活性中心浓度,发现至少在低转化率(10%)以内,活性中心浓度随聚合时间而线性增加;
