Chapter 2Chemical and Physical Properties of Sulphur Dioxide and Sulphur Trioxide

Ashar, Navin G.

Pages: 9 –19

[In order to appreciate the impact of the properties of liquid sulphur dioxide and liquid sulphur trioxide on future technology, it is important that an in-depth analysis of their properties be understood. Though the data given in this chapter are available in literature, the practical...

Chapter 3Manufacture of Sulphonating Agents Such as 25 and 65 % Oleums as well as Liquid Sulphur Trioxide

Ashar, Navin G.

Pages: 21 –26

[In order to produce gaseous as well as liquid trioxide it is essential that manufacture of oleums by absorption of sulphur trioxide from plant gases producing sulphuric acid. Pure (99 % +) sulphur trioxide can be produced by boiling 25 % oleum. This can be liquefied or used for producing 65 %...

Chapter 4Manufacture of Liquid Sulphur Dioxide

Ashar, Navin G.

Pages: 27 –33

[The conventional method of producing sulphur dioxide is by combustion of sulphur followed by absorption-desorption, drying and cryogenic condensation. This process is capital intensive, hazardous, saddled with corrosion and high utility consumption....

Chapter 5World Production of Liquid SO2 and SO3

Ashar, Navin G.

Pages: 35 –40

[The world production of liquid SO2 and liquid SO3 has increased considerably due to production of specialty chemicals required for petroleum, pharmaceutical and dye industires. The percentage distribution of demand is indicated in the table in Chap. 4. This is likely to change due to large scale...

Chapter 7Application of Sulphonation by Liquid SO3 Dissolved in Liquid SO2

Ashar, Navin G.

Pages: 45 –50

[One of the first applications is suggested for the production of Sulphamic Acid (NH2SO2OH). It is known as Sulphuric Acid which is packed in paper bags. The present technique of producing Sulphamic Acid is by reacting oleum with Urea. The process is very cumbersome and hazardous. The current...

Chapter 10Summary

Ashar, Navin G.

Pages: 69 –69

[This document is a path breaking narration for future technologies to carry out complex reactions of sulphonation. The book will be a guide to students of chemical engineering, technocrats and researcher’s exploring new techniques to produce sulphur based chemicals using liquid sulphur trioxide...
