摘要： A process to reduce carbonyl impurities in a carbonylation reaction for the production of acetic acid is described. The methyl iodide recycle stream which is directed to a carbonylation reactor for carbonylating methanol or methyl acetate to acetic acid, is treated to remove carbonyl impurities by reacting the methyl iodide stream formed in the reaction with an aqueous amino compound which reacts with the carbonyls to form water soluble nitrogenous derivatives, separating an organic methyl iodide phase from an aqueous derivative phase and distilling the methyl iodide phase to remove heavier impurities. The treatment of the methyl iodide recycle stream to the carbonylation reactor has been found to greatly reduce the carbonyls present in the acetic acid product. The formation of nitrile from the nitrogenous derivative during distillation may be minimized by adding water to the system.
摘要翻译：描述了在用于生产乙酸的羰基化反应中还原羰基杂质的方法。通过将反应中形成的甲基碘流与羰基化合物反应形成的氨基水合物反应，将甲基碘循环物流引导至用于将甲醇或乙酸甲酯转化成乙酸的羰基化反应器，以除去羰基杂质，形成水溶性含氮衍生物，将有机甲基碘相与水相衍生物相分离并蒸馏甲基碘相以除去较重的杂质。已经发现将甲基碘循环物流处理到羰基化反应器中大大减少了存在于乙酸产物中的羰基。在蒸馏过程中从含氮衍生物形成腈可以通过向系统中加入水来最小化。

摘要： Injection moldable, highly filled polymer composites are provided which exhibit high dimensional stability at temperatures above the glass transition temperature of the matrix polymer. The heat distortion temperature of the composites approaches that of the crystal melting temperature of the matrix polymer. The composite includes a polyaryletherketone matrix and at least two types of fillers each providing unique properties. The first filler is a reinforcing fiber filler which provides high strength and stiffness. The second filler is an non-thermoplastic immobilizing filler to immobilize the amorphous portion of the partially crystalline polyaryletherketone polymer and provides resistance to high temperature distortion. Notwithstanding its improved mechanical and heat resistant properties, the composite remains injection moldable and thus capable of low cost manufacturing.
摘要翻译：提供可注塑的，高度填充的聚合物复合材料，其在高于基体聚合物的玻璃化转变温度的温度下表现出高的尺寸稳定性。复合材料的热变形温度接近基体聚合物的晶体熔融温度。复合材料包括聚芳醚酮基质和至少两种类型的填料，各自提供独特的性质。第一填料是提供高强度和刚度的增强纤维填料。第二填料是非热塑性固定填料，用于固定部分结晶聚芳醚酮聚合物的非晶部分并提供耐高温变形性。尽管其机械和耐热性能得到改善，但复合材料仍然是可模塑的，因此能够实现低成本制造。

摘要： The palladium-catalyzed coupling of aryl and vinyl halides with vinylic compounds is disclosed. A preferred embodiment relating to the palladium catalyzed coupling of 4-substituted and 6-substituted-2-methoxynaphthalene to form nabumetone is also disclosed. The beauty of this novel reaction is that methylvinylketone, normally employed by the art directly as-is for the preparation of nabumetone, is formed in situ. We have discovered a mechanism to take advantage of the in situ formation of methylvinylketone, thus avoiding the use of expensive, toxic, and unstable methyl vinyl ketone feed. This reaction may be employed for a variety of pharmaceutically active and non-pharmaceutical compounds.
