摘要： This invention is a method for forming hypohalous acid in a mass transfer device. The method comprises: (1) feeding into the device a stream of caustic solution comprising at least one alkali or alkaline earth metal of a hydroxide, oxide, hypohalite, bicarbonate, or carbonate; (2) feeding a stream comprising halogen gas into the device; (3) reacting at least some of the halogen gas with the caustic solution to form a solution containing hypohalous acid; (4) desorbing the hypohalous acid from the solution and into the stream of halogen gas; and (5) removing the stream of halogen gas from the device. In this method, the mass transfer device comprises a porous rotor which is permeable to the streams, and is rotated about an axis such that the streams flow through the rotor and the stream of caustic solution flows radially outward from the axis.

摘要： The present invention provides methods that are used to decolorize compositions containing one or more amines in the presence of one or more weak acids. Significantly, the weak acids, particularly organic acids such as glacial acetic acid, when used in combination with a heat treatment produce dramatically less by-products than do the stronger mineral acids, making heat treatments and subsequent separation techniques more effective while producing less waste. In some modes of practice, the weak acids do not need to be neutralized, eliminating neutralizing steps and waste streams associated with neutralization. Low color products can be obtained easily at very high yield as a consequence.
摘要翻译： 本发明提供了用于在一种或多种弱酸存在下使包含一种或多种胺的组合物脱色的方法。 重要的是，弱酸，特别是有机酸，如冰醋酸，当与热处理相结合使用时，产生的副产物比较强的无机酸显着减少，使热处理和随后的分离技术更有效，同时产生更少的废物。 在某些实践模式中，弱酸不需要中和，消除了与中和相关的中和步骤和废物流。 因此，可以以非常高的产率容易地获得低颜色产品。
