Abstract

Tetramethylene sulphone is made by heating at least two moles of ethylene with one mole of sulphur dioxide at super atmospheric pressure. The preferred reaction conditions are 250-350 DEG C., 400-600 atmospheres and ethylene to sulphur dioxide molar ratio between 2 and 10 to 1. An example is provided.
