Patent GB-991818-A (GB)
Title: Improvements in or relating to the preparation of sultones
IPC: C07D327/06
Filed: 1962-12-06
Abstract: Sultones are prepared by subjecting the reaction product of sulphur trioxide and 1-olefines containing 4-20 carbon atoms of the formula R3R2R1C-CH2-CH=CH2 where R1, R2 and R3 are hydrogen or aliphatic hydrocarbon groups to (a) distillation under reduced pressure, or (b) hydrolysis to give the hydroxy alkane sulphonic acid from which water is removed by heating at an elevated temperature under vacuum and/or in the presence of a dehydrating agent.  The preferred olefines are the readily obtainable straight chain compounds and those containing up to 7 carbon atoms, particularly butene-1. The sulphur trioxide used, preferably in amounts of 1-2 mols. per mol. of olefine, may be in the gaseous, preferably diluted with an inert gas, or solid state or in a solution, e.g. in liquid sulphur dioxide or sulphuric acid, or as an addition compound of, e.g. dioxane or pyridine. The reaction is carried out in a known manner, preferably in a gaseous or liquid medium at temperatures exceeding 60 DEG  C.  The sultones obtained by treating the sulphonation product by method (a) may be mixed with volatile unsaturated sulphonic acids from which they are separated by fractional distillation.  In method (b) the primary reaction product may be hydrolysed by boiling with water and the resulting hydroxy sulphonic acid separated as the free acid or, if alkaline earth hydroxides are used to remove the sulphuric acid present as sulphate, as the alkaline earth sulphonate. Alternatively, the hydrolysis mixture can be neutralized with alkali metal hydroxide and the resulting salts separated on the basis of their different solubilities in, e.g. alcohol/water mixtures. The hydroxy sulphonate is converted to the free acid by treatment with an acid, e.g. hydrochloric, or an ion-exchanger.  Water is removed from the acid to give the sultone by heating at above 100 DEG  C., preferably in the range 120-180 DEG  C.  Dehydration is facilitated by reduced pressure and/or the use of a dehydrating agent, defined as a liquid unmiscible with and with a higher boiling-point than water, e.g. xylol.  Process (b) can be carried out in one step according to the method of Specification 908,317. Examples describe the preparation of sultanes from butene, hexene and octene. The 1,3-butane sultone is characterized through its reaction products with thiophenol, 4-chlorophenol and pyridine.  Reference has been directed by the Comptroller to Specification 774,563.
