  • Reaction accelerator and method of producing urethane compound, thiourethane compound, amide compound, or urea compound using same
    Patent number: 9656952
    Abstract: A reaction accelerator is provided which is used in a reaction of a compound including an isocyanate group that is not directly bonded to an aromatic ring in a molecule with a compound including an active hydrogen-containing group and is formed of a compound including a halogenated carbamoyl group. A production method is provided which includes reacting a compound including an isocyanate group that is not directly bonded to an aromatic ring in a molecule with a compound including an active hydrogen-containing group to produce a urethane compound, a thiourethane compound, an amide compound or a urea compound, in which the reaction is performed in the presence of the reaction accelerator.
