    • There is disclosed a novel process for the preparation of 1,4-diazabicyclooctane dihydrohalides having the formula ##STR1## wherein each R is independently selected from the group consisting of hydrogen, lower alkyl, aryl, aralkyl, and cycloalkyl, and X is chlorine or bromine, said process comprising heating at a temperature of at least about 100.degree. C. and in a dipolar aprotic solvent certain novel dihaloalkylene diamines. Neutralization of the dihydrohalides provides the corresponding 1,4-diazabicyclooctane free bases.Also disclosed are certain novel 1,4-diazabicyclooctane diammonium dihalides formed as intermediates in the above process and a process for their conversion to the 1,4-diazabicyclooctane dihydrohalides and free bases thereof.The 1,4-diazabicyclo compounds produced in accordance with the invention find particular utility as catalysts in the preparation of polyurethanes from organic polyols and polyisocyanates.
    • 公开了一种制备具有式“IMAGE”的1,4-二氮杂双环辛烷二氢卤化物的新方法,其中每个R独立地选自氢,低级烷基,芳基,芳烷基和环烷基,X是氯或 溴,所述方法包括在至少约100℃的温度和在偶极非质子溶剂中加热某些新的二卤代亚烷基二胺。 二氢卤化物的中和提供相应的1,4-二氮杂双环辛烷游离碱。 还公开了在上述方法中形成作为中间体的某些新的1,4-二氮杂双环辛烷二卤化二铵及其转化为1,4-二氮杂双环辛烷二氢卤化物及其游离碱的方法。 根据本发明制备的1,4-二氮杂双环化合物在从有机多元醇和多异氰酸酯制备聚氨酯中特别有用。

    • Disclosed is an improved process for the production of organic polyisocyanate-based molded polymers prepared from at least one organic polyisocyanate and at least one polyol wherein there is employed an internal mold release agent comprising an amino-polysiloxane having at least one group of the formulaRNH-alkylene--O--bonded to a silicon atom of a polysiloxane, wherein R is selected from the group consisting of hydrogen, lower-alkyl, cycloalkyl, and ECHR"CHR'-- wherein E is an electron withdrawing group and R' and R" are independently selected from the group consisting of hydrogen and methyl.The molding process can be repeated many times before the mold surfaces must be cleaned or treated with release agent. The ease of release of the molded polyurethanes makes the process particularly suitable for RIM production methods.
    • 公开了一种用于生产由至少一种有机多异氰酸酯和至少一种多元醇制备的有机多异氰酸酯基模制聚合物的改进方法,其中使用内部脱模剂,其包含具有至少一个式RNH的氨基 - 聚硅氧烷 - 亚烷基-O-键合到聚硅氧烷的硅原子上,其中R选自氢,低级烷基,环烷基和ECHR'CHR',其中E是吸电子基团,R'和R “独立地选自氢和甲基。 在模具表面必须用脱模剂清洁或处理之前,可以重复成型过程多次。 模制聚氨酯的易释放使得该方法特别适用于RIM生产方法。
