Description
Osamu Shimomura leads a team on a hidden catalyst for urethane making. Their study from twenty twenty-four deals with DABCO inside zirconium phosphate layers. The mix was tested with a standard isocyanate and butanol.
At room temperature the catalyst showed no activity. At higher heat it became strongly active. Viscosity rose fast at that heat in half an hour. Release of the amine from the layers was tracked. Butanol proved key to freeing the amine guest. The other liquid showed no such release signs. Two end group monomers were also tested.
