Abstract: By using a rush membrane, the mesohydric tautomerism of thiourea (I) has been confirmed. I isomerizes as follows: (H₂N)₂CS ↹ H₂NC(:NH)CSH. The osmosis through the rush membrane in a soln. of thiourea appears to be neg.; the vol. of outgoing thiourea is greater than the vol. of H₂O coming in through osmosis.
