氧氯化催化剂的能量标准在所述假设下减少到与Deacon工艺的催化剂相关的能量标准。分析主要涉及作为温度的函数的标准自由能变化，与金属氯化物与氧的反应，以及金属氯氧化物和氧化物与氯化氢的反应有关。使用氯化铜（II）/氧化物催化剂对的已知催化活性作为指导，从能量上评估其它二价、单价、三价和四价氯化物/氧化物对单独和组合的可能值。结果表明，解释了专利文献中给出的关于活性催化剂的许多技术事实。
The energetic criteria for oxychlorination catalysts are reduced under stated assumptions to energetic criteria associated with catalysts for the Deacon process. The analysis is mainly concerned with the standard free-energy changes as a function of temperature, associated with the reactions of metal chlorides with oxygen, and of metal oxychlorides and oxides with hydrogen chloride. Using the known catalytic activity of the copper(II) chloride/oxide catalyst pair as a guide, the possible value of other divalent, monovalent, trivalent and tetravalent chloride/oxide pairs alone and in combination is assessed energetically. The results are shown to explain a number of technological facts concerning active catalysts given in the patent literature.
