Versuchsvorschrift

To 22.2 g (0.10 mole) of 3-(2-aminoethylamino)propyltrimethoxysilane under nitrogen was added 29.5 g (0.10 mole) of octadecylisocyanate over a 45 min. period. The reaction temperature rose to ca. 70° C. Upon cooling to ambient temperature, the product solidified to a white wax. IR (neat film) 3300, 2900, 1620, 1570, 1470, 1090 cm-1. NMR (CDCl3) 0.4-1.0 (m; 5H), 1.1-2.0 (m; 34H), 2.4-2.8 (m; 2H), 2.9-3.4 (m; 7H), 3.55 (s; 9H), 5.5 (br s; 2H) ppm.

Aufarbeitung

  1. customrose to ca. 70° C
