Abstract: NOVEL TRIS-(ORGANOSILYL-METHYL)-AMINES OF THE GENERAL FORMULA

(RO-)NSI(CH3)2N-CH2-13N

IN WHICH R IS AN ALKYL RADICAL HAVING 1 TO 4 CARBON ATOMS AND N IS 1, 2 OR 3 AND CONDENSATION PRODUCTS DERIVED THEREFROM AND CORRESPONDING TO THE GENERAL FORMULA

2,6-BIS((R-O-)(N-1),2,6-DI(CH3-)(3-N),4-((R-O-)N-

SI(-CH3)(3-N)-1-OXA-4-AZA-2,6-DISILACYCLOHEXANE

ARE USEFUL INTERMEDIATES, SURFACTANTS AND PRIMERS. THEY ARE PRODUCED BY INTRODUCING ANHYDROUS AMMONIA INTO A SOLUTION OF A BROMOMETHYL-ALKOXYSILANE OF THE GENERAL FORMULA

(RO-)NSI(CH3)-N-CH2-BR

UNDER ATMOSPHERIC PRESSURE, THE SOLVENT BEING A POLAR APROTONIC COMPOUND THE DIELECTRIC CONSTANT OF WHICH IS GREATER THAN 25 AT 20*C., PREFERABLY ACETONITRILE, AFFECTING REACTION BETWEEN THE AMMONIA AND THE SILANE AT A TEMPERATURE BETWEEN -30*C. AND THE BOILING POINT OF THE REACTION MIXTURE, AND SEPARATING THE TRISAMINE FROM AMMONIUM BROMIDE AND THE SOLVENT. OPTIONALLY, THESE TRIS-AMINES ARE HYDROLYZED WITH WATER TO GIVE THE ABOVE CONDENSATION PRODUCTS.
