摘要： A process for preparing alkali silicate-polyisocyanate composites without catalyst separation. The process involves blending a catalyst and a polyisocyanate to form a first component, and blending an alkali silicate and water to form a second component. The first and second components are then mixed together to form a reactive mixture that reacts to form a hardened composite. The progression of the reaction proceeds without excessive foaming, high exotherms, or the release of an offensive odor. Sodium silicate-polyisocyanate composites prepared according to the above process, and a process for using the alkali silicate-polyisocyanate composites to consolidate and seal various types of formations in mining, tunneling, and other construction projects are also disclosed. Any void volume which is capable of receiving a flowable precursor of a composite formulation according to the invention prior to its cure is suitable for treatment according to the present invention.

摘要： The present invention concerns a process for providing tertiary amine products which are color-stable, and have a greatly reduced tendency to take on color during their storage. According to the invention, an ethyleneamine derivative is added to the distillation pot prior to or during the distillation of the tertiary amine product. Preferably, the ethyleneamine derivative has a higher boiling point than the desired tertiary amine product so as to preclude the ethyleneamine from distilling over with the tertiary amine.

摘要： Inclusion of a branched alcohol in the catalytic hydrogenation reaction involving an aliphatic nitro compound dramatically increases the efficiency of the conversion of nitro groups into amino groups. This discovery is of particular value in the production of polyalkyleneamines via nitration of a polyalkene, such as a polybutene, and its subsequent reduction. The polyalkyleneamines so produced are useful as dispersant additives for motor oils and fuels.

摘要： Identified herein are inhibitors which may be added to the boiling pot portion of a distillation apparatus prior to or during the distillation of an alkylene carbonate. The inhibitors retard the occurrence of undesirable reactions of the alkylene carbonate with itself and impurities present in the pot, and hence greatly reduce or minimize the formation of undesirable by-products which otherwise tend to reduce overall yields of alkylene carbonate recovered by the distillation process. Higher distillation temperatures at higher pressures over the prior art are possible without attendant losses of significant amounts of recovered alkylene carbonate, which confers heretofore unseen flexibility in alkylene carbonate distillation.
摘要翻译： 本文所述的是在碳酸亚烷基酯蒸馏之前或期间可以加入到蒸馏装置的沸腾锅部分的抑制剂。 抑制剂阻碍碳酸亚烃酯本身和存在于罐中的杂质的不期望的反应的发生，因此大大减少或最小化不期望的副产物的形成，否则倾向于降低由蒸馏过程回收的碳酸亚烃酯的总产率。 与现有技术相比，在较高压力下的较高蒸馏温度是可能的，而不需要大量回收的碳酸亚烃酯的损失，这在碳酸亚烷基酯蒸馏中赋予迄今未见的灵活性。

摘要： This invention concerns a process to provide high purity alkylene carbonate though use of multiple distillations wherein the unused fractions are recycled to the reactor. The high purity alkylene carbonate may be further purified by use of carbon to produce electrochromic or photochromic grade alkylene carbonate by reducing its UV absorbance.
