Thus when an ammonia-natural gas mixture is compressed and then is subsequently allowed to flow through a gas pipeline, the ammonia cools the mixture as it expands. This is regarded as an additional advantage [1261].

From these data, the conclusion could be drawn that the surface chemistry plays a role in the discoloration mechanism of tested system. The surface chemistry must be involved in the partial oxidation of the antioxidant material presumably by the photo-generation of radicals from the Ti02 crystal but, the data do not suggest clues about the role of the ammonia, nature of the phenol moiety and/or surface adsorption.
