Isopropanol, water, dichloromethane how to be solved

You can place one end time, dichloromethane is easy to volatilize,

Most of the isopropanol

Isopropanol and water isopropanol and dichloromethane are mutually soluble

First concentrate, try

I suggest you stir, still see it in a while, I used to deal with this situation before, and the experiment cannot be anxious.This may be related to the material you synthesized.

Very normal, sometimes extracting simple aqueous phase and dichloromethane will emulsify, one hand, it is possible that the dissolution product concentration is too large, and the effect of emulsifiers and surfactants, considering adding more solvent and moisture layersOn the other hand, pure isopropyl alcohol can be eliminated from water and dichloromethane, and isopropyl alcohol ratio determine the degree of mutual solvent. It is also added to add dichloromethane and water, or add saturated NaCl to increase ionic strength, and the hierarchical effect is very obvious.Further, acid and alkaline can also cause emulsifying mobilization, preferably neutralization

This situation often occurs, so it is better to concentrate the solvent to extract the solvent.
