1 aqueous chloride in a hard quartz boat in the tube, with pressure-relief devices (to maintain high mercury 25 cm) at a rate of 1 cubic cm/SEC bubbled into clean, dry HCl gas, maintain 3 h under 70 ℃ temperature, rising up to 160 ℃, 1 ~ 2 h, and then slowly heat up to 250 ℃, to transfer quartz tube strike opened the oven to keep dry (sulfuric acid do desiccant), after cooling, the product is transferred to hot, dry reagent bottles, seal can be quickly.
The reactants are weighed according to stoichiometry. The reactants are packed in quartz tube suspended in the electric furnace (d=13 ~ 25mm,l=7 ~ 25cm). The selected electric furnace should be able to make the temperature of each part of the sample tube as consistent as possible. Reaction tube inlet connected to the side of the mouth of the distillation flask (distillation flask with teflon tube), exports are connected to the condensate receiver (even with polyethylene pipe), each for a polyethylene pipe needs to be replaced after the experiment, the ptfe tube not affected by reaction device (as shown in figure Ⅲ 2).
CCl4 was added from the sample tube to the distilled flask at a rate of 0.22~0.27g/(min·cm). The flow rate of CCl4 was controlled by the screw clamp on the teflon tube of the distilled flask. Keeping the temperature of the distillation flask with electric heating at 100 ℃, electricity tropical maintain preheating section (connected to the distillation flask and reaction tube side tube section) in the temperature of 120 ℃.
According to the requirements of the following control reactor temperature: 500 ℃ 6 h, 15 h, 550 ℃ of 600 ~ 650 ℃ for 8 h.
After the reaction is completed, Ar or other inert gas is filled through the inert gas inlet. Disconnect the reaction tube, attach the piston, connect the vacuum system, vacuum, and seal
