extraction of very polar water soluble compounds from H2O can be done with the the mixture 7:3 CHCl3/iPrOH. Some other people suggest ratio 2:1 or 3:1.

Isobutanol (2-methyl-1-propanol0 is quite immiscible with water at room temperature and can be used to extract polar compounds. It is a single pure compound unlike some mixtures that can be used and it can be dried azeotropically. The azeotrope splits into two layers in the Dean-stark trap and the isobutanol can be recovered!
