Procedure

3-Aminopropyltrimethoxysilane (20 g, 0.111 mol) was added to ethylene carbonate (9.82 g, 0.111 mol). The mixture homogenized while stirred and then became slightly warm. Stirring continued for 24 hours to give 2-hydroxylethyl N-(3-trimethoxysilylpropyl)carbamate. Distilled water (18 g) was added drop-wise under stirring to a mixture of 2-hydroxylethyl N-(3-trimethoxysilylpropyl)carbamate (15 g), methanol (5 g) and acetic acid (0.1 g) to form a hazy solution. Stirring continued for 12 hours resulting in clear water-miscible liquid (39.37 wt. % of hydroxyl-functional carbamoyl organosilicon compound(s)).
