Abstract: Unsymmetrically-substituted alkanolamino-s-triazines are prepared in excellent yields by the reaction of cyanuric chloride with a reactive hydrogen-containing compound and an alkanolamine in the presence of an acid acceptor. The resulting triazines are effective catalysts for the preparation of rigid cellular foams.
