A spectrophotometric method for determination of epoxide concentration and epoxide hydrolase activity has been developed by using the reaction of epoxide with 4 ( p nitrobenzyl) pyridine followed by alkalization. 研究了在弱碱性条件下,利用环氧化物与4-(对硝基)苄基吡啶之间的显色反应测定环氧化物含量,进而计算环氧化物水解酶活性的分光光度法。
Using Ru on the surface of hydroxyapatite ( RuHAP) as heterogeneous catalyst, p-nitrobenzaldehyde was prepared by oxidation of p-nitrobenzyl alcohol at atmospheric pressure. 经Ru(Ⅲ)交换的羟基磷灰石(RuHAP)作多相催化剂,用氧气常压氧化对硝基苯甲醇制备了对硝基苯甲醛。
