Title:
PRODUCTION METHOD OF ALIPHATIC/ALICYCLIC ISOCYANATE
Document Type and Number:
Japanese Patent JP2003096043
Kind Code:
A
Abstract:
To produce an aliphatic/alicyclic isocyanate by the phosgenation in gas phase of an amine while avoiding the contamination of a reactor and the blockade of a gas flow channel caused by the formation of solid deposits.
This new method for producing the aliphatic/alicyclic isocyanate and tri-isocyanate comprises phosgenating an aliphatic/alicyclic diamine and triamine in a gas phase while accelerating at least one of the reactants in an area in which the reactants are mixed.
