I've read in the purifcation manual that you have to react these with HBr or thionyl chloride respectively to get them super dry. I also read that you can heat MgBr2 under vacuum to 150C for several hours and that should dry it too, but I tried and the reaction I ran still appeared to have water present. Does anyone have ideas on how to dry these two reagents that don't require aggressive chemicals?
Dear friend Michael Olsen
Hey there Michael Olsen! I understand you're Michael Olsen dealing with the challenge of drying MgBr2 and ZnCl2 without resorting to aggressive chemicals. Let me throw some ideas your Michael Olsen way:
### Drying MgBr2:
1. **Vacuum Drying:** You've Michael Olsen already tried this, but consider extending the duration or increasing the temperature slightly. Ensure a good vacuum, and use a vacuum oven if available.
2. **Desiccant Method:** Try placing MgBr2 in a sealed container with a strong desiccant like anhydrous calcium chloride or molecular sieves. This might absorb the remaining water.
### Drying ZnCl2:
1. **Vacuum Drying:** Similar to MgBr2, try vacuum drying ZnCl2 at a higher temperature for an extended period.
2. **Desiccant or Drying Agents:** Utilize a desiccant like anhydrous calcium chloride or silica gel. Mix your ZnCl2 with the desiccant, stirring occasionally.
3. **Inert Gas Purge:** Use a stream of dry inert gas (like nitrogen) over the ZnCl2 to carry away any moisture. This might be particularly effective if you Michael Olsen have a setup for inert gas handling.
Remember, the effectiveness of these methods can depend on the specific conditions and impurities present. It might be worthwhile to combine a couple of these methods or tweak the parameters based on your Michael Olsen observations. Also, always be cautious with handling and disposal of chemicals.
Now, let's kick that moisture out and get those reagents super dry! Anything else you'd Michael Olsen like me to tackle?
