実験手順

To a 500 ml round-bottom flask equipped with condenser, thermometer and a stirrer were introduced 118 g. (1.0 mole) of 2,5-dihydrothiophene 1,1-dioxide, 200 ml. of 70% by weight aqueous ethanol and 37 g (0.5 mole) of 1,2-diaminopropane and 10 ml. of a 0.1 N sodium hydroxide solution. The reaction mixture was heated at 85°C for 20 hours. The solvent was then removed under a reduced pressure. The product, N,N'-bis(1,1-dioxotetrahydro-3-thienyl)-1,2-diaminopropane was obtained as a viscous liquid. The infrared spectrum of this product was superimposable with that of Example 3. This product also evaluated in high resiliency, flexible polyurethane foam (see Example 19).
