摘要： This invention relates to urethane linked hydroxy aromatic isocyanates and to a process for producing such urethane linked hydroxy aromatic isocyanates. The compositions are formed by reacting one equivalent aromatic diisocyanate with one equivalent of an alkylene polyol under conditions such that only one of the isocyanate groups react with the hydroxyl group of the polyol. Conditions are controlled such that the urethane linked hydroxy aromatic isocyanates are formed. The resulting product is suited for producing a variety of elastomers including a one component polyurethane elastomer.

摘要： This invention relates to urethane linked mixtures of 2,4- and 2,6-toluenediisocyanates (ULTDI dimers) having low melting points and to a method of forming these systems. The urethane linked toluenediisocyanates containing from 45-90% of the 2,4- and 10-55% of the 2,6- isomer by weight are formed by reacting two moles of an appropriate isomer mix of toluenediisocyanate, with one mole of a specific alkylene glycol, e.g., 1,2-butanediol, diethylene glycol or dipropylene glycol under conditions such that essentially only one of the isocyanate groups on a toluenediisocyanate molecule reacts with a hydroxyl group of the glycol. Conditions are controlled such that the urethane linked toluenediisocyanates are formed. The resulting product, which has two unreacted isocyanate groups, is suited for producing a variety of elastomers including polyurethane polyurethane/urea or polyurea elastomers.
摘要翻译：本发明涉及具有低熔点的2,4-和2,6-甲苯二异氰酸酯（ULTDI二聚体）与形成这些体系的方法的氨基甲酸酯连接的混合物。含有45-90％的2,4-和10-55％的2,6-异构体的氨基甲酸酯连接的甲苯二异氰酸酯是通过使两摩尔的甲苯二异氰酸酯的合适异构体混合物与1摩尔特定的亚烷基二醇，例如1,2-丁二醇，二甘醇或二丙二醇，在甲苯二异氰酸酯分子上基本上只有一个异氰酸酯基与二醇的羟基反应的条件下进行。控制条件使得形成氨基甲酸酯连接的甲苯二异氰酸酯。得到的具有两个未反应的异氰酸酯基的产物适用于生产各种弹性体，包括聚氨酯聚氨酯/脲或聚脲弹性体。

摘要： This invention pertains to a process for preparing mononuclear aromatic amines by reacting an alkali metal amide with a mononuclear aromatic compound, e.g., benzene and toluene. The reaction is carried out in the presence of a metallic hydrogenation catalyst, suitably copper, nickel, rhodium or cobalt, the metal being present in an amount sufficient for catalyzing the reaction. The amine then is formed by adding a protonating agent to the resulting reaction product formed by the reaction of the alkali metal amide with the aromatic compound. The addition of the protonating agent liberates the amine.

摘要： The conversion of alkyl diaminobenzenes to the alkyl amino benzenes is carried out by contacting the alkyl diamino benzene with hydrogen in the presence of a nonsupported cobalt catalyst. Optionally, the reaction is carried out in the presence of water so that the water insoluble product formed can be separated from the water soluble reactants and by-products.
