The catalytic synthesis of n - propyl carboxylate with ammonium ferric sulfate 硫酸鐵銨催化合成羧酸正丙酯
Tri - n - propyl amine 三正丙胺
The reaction conditcons for di - n - propyl chlorophosphate preparation were studied 在此工藝條件下,二正丙基亞磷酸酯的平均合成收率達(dá)89 . 4 % 。
The structure of di - n - propyl phosphite and propaphos prepared were identified by ir and 1h - nmr spectra 二正丙基亞磷酸酯和丙蟲磷的結(jié)構(gòu)用ir和1h - nmr表徵。
The experiments illustrated that sno2 thin films of 20 layers had high sensitivity toward low concentration ( 5ppm ) of n - propyl alcohol gas at room temperature 多層薄膜室溫下對(duì)正丙醇?xì)怏w具有良好的敏感特性,可檢測(cè)到5ppm 。
Based on orthogonal test , the factors influencing the synthesis of di - n - propyl phosphite , such as reaction temperature , reaction time and molar ratio of reactant , were investigated 通過正交優(yōu)化試驗(yàn),考察了溫度、時(shí)間和物料配比對(duì)二正丙基亞磷酸酯的合成收率的影響。
An organ phosphorous pesticide , 4 - ( methylthio ) phenyl di - n - propyl phosphate ( propaphos ) , and intermediates , di - n - propyl phosphite and di - n - propyl chlorphosphate , were synthesized by using n - propanol , phosphorus trichloride , 4 - ( methylthio ) phenol , etc . as starting materials 摘要以正丙醇、三氯化磷、 4 -甲硫基苯酚等為原料,合成有機(jī)磷殺蟲、殺菌劑丙蟲磷以及中間體二正丙基亞磷酸酯等。
