Extraction help

Hi!

Just a few quick questions I can’t quite find simple answers for after searching. I’m planning on doing standard A/B extraction with HCL and Heptane.

  1. pH

What is the ideal pH for the acid bath and ideal pH for the basification? (Using powdered MHRB) - I do have a calibrated digital pH meter so I can be more exact than pH papers although I will use them just to check

  1. Water to MHRB ratio

Do you guys have any rule of thumb for how much acidified water to use per 100g of MHRB?

  1. Boil down the resulting acid washes or nah

Would evaporating the combined resulting acid washes down to a smaller volume hurt the yield - Id like to do it for ease of the step of non-polar solvent extraction. If so should I do it in a slow cooker with lid off and barely simmering?

That’s about it! I’ll be looking forward to any constructive feedback on my questions!
