title: Replacing HCl by solid acids in industrial processes: synthesis of diamino diphenyl methane (DADPM) for producing polyurethanes.
abstract: Delaminated zeolite catalysts allow replacement of HCl in the production of DADPM: they offer higher activity and catalyst life than conventional zeolites, and their structured external surface controls product selectivity.
