Activation of Catalysts in Olefin Reactions


WE regret to have left unmentioned the facts referred to by Dr. Hickinbottom. They may have some bearing on our findings, but it is too early to discuss this at length. We may mention, however, that the action of titanium chloride (TiCl4) on isobutene at low temperature which we found to be induced by traces of water is not affected by dry hydrogen chloride.
