摘要： N-monosubstituted carbamic acid esters are thermally split on a continuous basis in a tube reactor. The carbamic acid ester which is flowed down or passed over the inner wall of a tube reactor is thermally split at a temperature of from 150.degree. to 450.degree. C. and under a pressure of from 0.001 to 20 bar into at least two fractions. One fraction is predominantly isocyanate and a second fraction is predominantly hydroxyl compound. These fractions may be separated by removing one as a gaseous fraction formed under the splitting conditions from the head of the reactor and collecting the second fraction as a liquid which accumulates at the base of the reactor. If both fractions are gaseous under the splitting conditions, they are both removed from the head of the reactor and subsequently separated by fractionating columns for example. This process is particularly advantageous in that isocyanate and hydroxyl fractions are obtained in high yield without using a solvent.
摘要翻译： N-单取代氨基甲酸酯在管式反应器中以连续的方式热分解。流过或流过管式反应器内壁的氨基甲酸酯在150℃至450℃的温度和0.001至20巴的压力下热分解成至少两个馏分。一个部分主要是异氰酸酯，第二部分主要是羟基化合物。这些级分可以通过除去在分离条件下从反应器的头部形成的气态馏分来分离，并将第二馏分作为积聚在反应器底部的液体进行收集。如果两个馏分在分解条件下都是气态的，则它们都从反应器的头部移出，并随后通过分馏塔例如分离。该方法特别有利的是在不使用溶剂的情况下以高产率获得异氰酸酯和羟基部分。

摘要： The present invention relates to a process for the production of oligomeric polyisocyanates by the dimerization or trimerization of a portion of the isocyanate groups in organic polyisocyanates in the presence of tertiary phosphines or in the presence of a peralkylated phosphorus acid triamides as catalyst, followed by termination of the dimerization and/or trimerization reaction at the required degree of oligomerization by the addition of a catalyst poison, characterized in that a sulfonyl isocyanate is used as the catalyst poison.The present invention also relates to the use of the oligomeric polyisocyanates obtained by this process, optionally in admixture with unreacted starting polyisocyanate or optionally blocked by blocking agents for isocyanate groups, as the polyisocyanate component in the production of polyurethane plastics.
