Liquid Sulphur Dioxide as a Solvent of Sulphur Trioxide
Series: SpringerBriefs in Applied Sciences and Technology
Introduces readers to use of the special properties of liquid SO2 and liquid
SO3for research on innovative process of sulphonation reactions.
Illustrates the use of liquid SO3 for recycling the make-up of liquid SO2.
Explains auto-refrigeration due to evaporation of liquid SO2 to absorb heat of
exothermic reactions in high pressure reactor in order to recycle evaporated
sulphur dioxide.
Describes a scheme of continuous reaction potentially reducing reactor size
and capital investment.
Offers insight on low utility consumption and safe and environmentally
friendly operations in industrial sulfonation.
This book presents a complete, in-depth analysis for on the impact of liquid sulfur dioxide and
liquid sulfur trioxide to carry out complex and difficult sulfonations, as well as consultancy for sulfuric acid with a CAPEX requirement of less than half, an area requirement less than onethird, and no emission of sulfur dioxide. The processes described in this volume represents an
innovative approach relevant to the current manufacturing processes of sulfuric acid, sulfamic
acid, para toluene sulfonic acid and other sulfonated product.
