Hindering CaO Reaction with Moisture.

Hindering CaO Reaction with Moisture.

Hindering CaO Reaction with Moisture.

(OP)
Hello People!

Please, I need help with this: Which solvent can be used to handle CaO in order to prevent it from reacting with water? I think it is some sort of oil, but I am not too sure. Please bear in mind that this is to be used on a large scale and so it would help if it were rather cheap.

Thank you very much in advance.

RE: Hindering CaO Reaction with Moisture.

1) Don't use oil, you will end up with a messy slurry.
2) Don't use any organic acid or alcohol or anything else with an OH; CaO will react to form Ca(OH)2.
3) Don't use anything with F; it will form CaF2.
4) Don't use anything with SO2, SO3, etc.
5) Don't use CO2 gas.
6) Suggest using dry N2 gas.

RE: Hindering CaO Reaction with Moisture.

If you are using this for storage of the CaO then add dessicant bags to the container and store it in a dry place. Tightly seal the container. CaO powder is stored like this in bulk.

If you can afford an all steel container with a vacuum draw, then this is an option, but still use dessicant.
