A process for the production of styrene is described. The process comprises dehydrating 1-phenyl ethanol in the liquid phase in the presence of a para- and ortho-toluenesulfonic acid mixture. The ratio of para-toluenesulfonic acid to ortho-toluenesulfonic acid is from 1:9 to 20:1. The process results in reduced heavies production, improved 1-phenyl ethanol conversion and selectivity, less reactor tube fouling, and lower corrosion rates.
