Participants

Reaction Steps

3-Aminopropyltrimethoxysilane (20 g, 0.111 mol) was mixed with ethylene carbonate (9.82 g, 0.111 mol) under slow stirring. The mixture became slightly warm. Stirring continued for 24 hours to give 2-hydroxylethyl N-(3-trimethoxysilylpropyl)carbamate. Hexylene glycol (39.3 g, 0.333 mol) was added drop-wise under stirring to a mixture of 2-hydroxylethyl N-(3-trimethoxysilylpropyl)carbamate (29.8 g, 0.111 mol), and sulfuric acid (0.1 g) and then heated at 50° C. and 15 mm Hg pressure for 4 hours. The methanol that formed was removed by distillation. The product was a clear, low viscosity liquid.
