| Introduction | praseodymium chloride is a blue-green needle-like crystal with a melting point of 786 ℃, a boiling point of 1700 ℃ and a relative density of 4.0225. The heptahydrate is a green triclinic crystal. Deliquescence, melting point 115 ℃, relative density of 2.25417, in the hydrogen chloride atmosphere to 108 ℃ when the loss of 6 molecules of crystal water, 180 ℃ into anhydrous. Both are easily soluble in water, hydrochloric acid and ethanol. |
| preparation | hydrochloric acid and praseodymium dioxide were reacted to obtain praseodymium chloride. |
| solubility in water (g/100ml) | grams dissolved per 100ml of water: 104g/20 ℃ |
| Use | used in the preparation of praseodymium metal and Praseodymium compounds, glass, ceramic coloring research reagents, biochemical Research used as a petroleum catalyst, can also be used in the production of metal praseodymium. |
| production method | the pure and dry HCl gas is introduced at the speed of 1 cm3/s, and the temperature is maintained at 70 C for 3H, and the temperature is gradually raised to 160 C for 1~2H, the temperature was then slowly raised to 250 ° C. While hot, the furnace was opened to transfer the quartz tube to a desiccator (concentrated sulfuric acid as desiccant), and after cooling, the product was transferred to a hot, dry reagent bottle and sealed quickly. 2 weigh the reactants according to the stoichiometric relationship, and the reactants are packed in a quartz tube (d = 13 ~ 25mm,l = 7 ~ 25cm) suspended in the electric furnace, the electric furnace should be selected so that the temperature of each part of the sample tube is as consistent as possible. The inlet of the reaction tube is connected to the side mouth of the distillation flask (the distillation flask is connected with a polytetrafluoroethylene pipe), and the outlet is connected to the condensation receiver (connected with a polyethylene pipe). The polyethylene pipe needs to be replaced after each experiment, however, the PTFE tube is not affected by the reaction (the device is shown in Fig. CCl4 was added dropwise from the sample tube to the distillation flask at a rate of 0.22 to 0.27g/(min · cm). The flow rate of CCl4 was regulated by a helical clip on a Teflon tube on the distillation flask. The temperature of the distillation flask was maintained at 100 ° C. With an electrothermal shield, and the temperature of the preheating portion (the side tube portion connecting the distillation flask and the reaction tube) was maintained at 120 ° C. With an electrothermal band. The temperature of the reaction furnace is controlled according to the following requirements: 500 C 6H, 550 C 15H, 600~650 C 8H. After completion of the reaction, Ar or other inert gas is charged through an inert gas inlet. Disconnect the reaction tube, match the piston, connect the vacuum system, vacuum, sealed preservation.
