CharacteristicsPropylene, under normal conditions, is a colourless, flammable gas of weak, sweetish odour, heavier than the air. Over the range of concentrations indicated above, it forms explosive mixtures with the air. Polymerisation quality propylene is produced at Olefins Department II, in the process of hydrocarbons pyrolysis. Propylene is extracted from the mixture of post-pyrolysis gases by means of distillation.
ApplicationsPropylene is used, among other applications, for production of the following chemicals:
