  A process for purifying p-phenylenediamine color developers in their free-base form. The process includes subjecting a solution containing p-phenylenediamine-type free base color developer to short path distillation which includes at least one of falling film evaporator, thin film evaporator, wiped film evaporator, or short-path evaporator. Another aspect is a method for preparing an acid salt from a p-phenylenediamine free base color developer. The method includes the steps of: a) dissolving a purified p-phenylenediamine free base derived from the short path distillation process in an organic solvent; b) contacting the dissolved free base distillate with an appropriate mineral acid; and c) crystallizing the color developer in the acid salt form.

  一种用于纯化游离态p-苯二胺显色剂的方法。该方法包括将含有p-苯二胺游离基显色剂的溶液经过短程蒸馏，其中至少包括下列一种：降膜蒸发器、薄膜蒸发器、刮板蒸发器或短程蒸馏器。另一方面，该方法还包括制备p-苯二胺游离基显色剂酸盐的方法。该方法包括以下步骤：a）将经过短程蒸馏过程得到的纯化的p-苯二胺游离基溶解在有机溶剂中；b）将溶解的游离基馏分物与适当的矿酸接触；c）以酸盐形式结晶显色剂。

  Hydroxy-substituted hydroxylamine antioxidants can be prepared by reacting hydroxylamine or a mono-substituted hydroxylamine, in free base form, with an epoxide. The antioxidant reaction product can be used without isolation from the reaction solution, and combined with a color developing agent to provide a photographic color developing composition in either concentrated or working strength formulations. The method for preparing the antioxidant is rapid and efficient because of the use of the free base form of the hydroxylamine reactant, higher temperatures (at or above 50°C) and certain molar ratios of reactants.

  羟基取代的羟胺抗氧化剂可通过羟胺或单取代的羟胺以游离碱形式与环氧化物反应制备。抗氧化剂反应产物无需从反应溶液中分离出来，可与显色剂结合使用，提供浓缩或工作强度配方的照相显色组合物。由于使用了羟胺反应物的游离基形式、较高的温度（50°C 或更高）以及反应物的特定摩尔比，制备抗氧化剂的方法快速而有效。
