Reaction Steps

About 121.0 g (1.0 mole) of 2-amino-2-(hydroxymethyl)-1,3-propanediol (THAM) was combined with 114.0 g (1.0 mole) of E-Caprolactone and 0.1 g stannous octanoate Sn(OCT)2. As the reaction mixture was slowly heated to 150° C., a clear solution was obtained. Infrared analysis of the reaction product showed no unreacted caprolactone. Upon heating the product cyclized to a hydroxy-oxazoline, and a strong absorption band at 6.0 microns in the infrared spectrum was observed. The product analyzed for 50.94% C, 9.29% H and 5.79% N.
