Issues with filtration and washing after the Grignard reaction
Thread Content
After the Grignard reaction is complete, filtration by suction or centrifugation is carried out; so how is washing performed thereafter? How should one stir to ensure thorough cleaning? When done manually, it requires a lot of physical effort, and the smell is also stronger!
Why was it sent twice? Please have the moderator delete this! Thank you! It seems it wasn’t sent at that time; an error was displayed!
Can’t it be done by directly pumping it into the washing tank for washing and then discharging it in layers?
Washing the Grignard filter cake in this way is problematic: firstly, the operating conditions are harsh (strong odors and high labor intensity); secondly, it’s not suitable for substances that tend to deliquesce and decompose easily!
