无锡高速分析仪器厂(中国人民解放军9759工厂)化学试剂研究所生产并纯化的二安替比林苯乙烯基甲烷(DAVPM),每克15元,3克包装。 该试剂由安替比林与肉桂醛缩合而成,分子式:C_(31)H_(30)O_2N_4,分子量490。试剂为白色粉末(有时略带黄色),熔点为114～115℃。试剂易溶於乙醇、丙酮等有机试剂而不溶於水,纯品固体和溶液均较稳定(产品中若含肉桂醛,极易变质)。 DAVPM在酸性介质中具有还原性,其氧化还原电位在硫酸介质中为0.600～0.683V之
Wuxi High Speed Analytical Instrument Factory (People’s Liberation Army 9759 Factory) Institute of Chemical Reagents produced diantipyryl styryl methane (DAVPM), 15 grams per gram, 3 grams packaging. The reagent is prepared by the condensation of antipyrine and cinnamaldehyde. The molecular formula is C 31 H 30 O 2 N 4 and the molecular weight is 490. Reagents for the white powder (sometimes slightly yellow), the melting point of 114 ~ 115 ℃. Reagents soluble in ethanol, acetone and other organic reagents and insoluble in water, pure solid and solution are more stable (if the product contains cinnamic aldehyde, perishable). DAVPM in the acidic medium has a reduction, the redox potential in the sulfuric acid medium is 0.600 ~ 0.683V
