| titleOfInvention | Method for preparing arsenic hydride by adopting arsenide hydrolysis method |
| abstract | The invention discloses a method for preparing arsenic hydride by adopting a arsenide hydrolysis method. The method comprises the following steps: putting a certain amount of zinc in one ceramic plate; putting the plate in a high-temperature-resistance quartz tube; putting a certain amount of metal As in the other ceramic plate, and putting the other ceramic plate at the other end of the quartz tube; introducing nitrogen to completely replace air; heating the end, filled with zinc, of the quartz tube to 700 DEG C, and heating the end, filled with arsenic, of the quartz tube to 300-500 DEG C to cause a combination reaction between arsenic steam and zinc to generate Zn3As2. According to the method, the raw material reacts with diluted hydrochloric acid or diluted sulphuric acid to generate arsenic hydride, wherein the arsenic hydride comprises H2O, O2, N2, H2, PH3 and other impurities. The process is simple, typical and mature, so that priority is given to the process in arsenic hydride synthesis. |
