    摘要： The present invention relates to gas phase phosgenation of amines for preparation of isocyanates. In the present invention, phosgene is prepared by reacting chlorine with an excess of carbon monoxide in a gas phase. The obtained phosgene-containing reaction mixture is divided into two streams by a thermal and/or a membrane separating process. The first stream is a low-carbon monoxide stream of no more than 1% by weight of carbon monoxide, based on a total weight of the first stream. The second stream is a carbon monoxide-rich stream of more than 10% by weight of carbon monoxide, based on a total weight of the second stream. The first stream is used as the phosgene-containing reactant stream in the gas phase phosgenation of amines to prepare isocyanates. The second stream can be recycled into the phosgene synthesis.

    摘要： The invention relates to a process for preparing isocyanates by reacting the corresponding amines with phosgene, optionally in the presence of an inert medium, in which phosgene and amine are first mixed and converted to the isocyanate in a reactor, and in which a reaction gas which comprises isocyanate and hydrogen chloride leaving the reactor is cooled in a quench by adding a liquid quench medium to form a mixture of reaction gas and quench medium as the product stream. The walls of the quench are essentially completely wetted with a liquid.

    摘要： The invention relates to a process for preparing isocyanates by reacting the corresponding amines with phosgene in the gas phase, optionally in the presence of an inert medium, in which the amine is evaporated in an evaporator to give an amine-comprising gas stream, the phosgene is mixed into the amine-comprising gas stream, and the amine and the phosgene are converted to the isocyanate in a reactor, wherein the temperature of surfaces in contact with the gaseous amine is kept above the dew point limit of the amine-comprising gas stream. The invention further relates to an apparatus for preparing isocyanates by reacting the corresponding amines with phosgene in the gas phase, comprising an evaporator to evaporate the amine and a reactor in which the reaction is effected, and means of connection of evaporator and reactor, wherein surfaces which can come into contact with gaseous amine are provided with a coating which is not wetted by amine or have an averaged roughness depth Rz to DIN ISO 4287 of not more than 10 μm, and/or the apparatus has no dead spaces or thermal bridges.

    摘要： Disclosed are novel compositions capable of catalytically trimerizing organic isocyanates said compositions comprising solutions of the reaction products obtained by reacting in an inert solvent in substantially equimolar proportions electron-rich ketene-aminals with electron-poor olefins having the respective formulae (I) and (II) ##STR1## The variously substituted electron-rich ketene-aminals (I), as the name implies, have high electron density associated with the double bond because of the two tertiary amine groups while the electron-poor olefins (II) have the opposite situation due to the presence of electron withdrawing substituents R.sub.9 and R.sub.10.Also discosed is an improved process for trimerizing organic isocyanates using the above catalyst compositions including the preparation of polyisocyanurate polymers and isocyanurate-modified polyisocyanates.
