The invention discloses a 2 - (thio - 2 - armor oxygen ethyl) benzothiazole and its preparation method and application, which belongs to the thiazole heterocycle with asymmetric structure of compound preparation and operation. The invention 2 - (thio - 2 - armor oxygen ethyl) benzothiazole compounds of the formula C10 H11 NOS2 , Referred to as MOBT, Mr225.33. Its preparation is to measure a certain amount of 2 - mercaptobenzothiazole three flasks, adding acetone to dissolve, then by an amount of H2 O dissolving equimolar of KOH and adding three flasks, in 60 °C conditions and heat to reflux dropwise adding an equimolar 2 - bromo ethyl methyl ether, reflux reaction 6h and separate the solvent to obtain. This invention utilizes the difference between the rate of extraction to the palladium-platinum MOBT to realize the effective separation of palladium-platinum in the feed liquid and, in the low acidity of in hydrochloric acid medium, MOBT to palladium has better selectivity extraction performance, palladium-platinum separation coefficient is high, good separation effect.
