Hydroxy alkane sulphonates

The combination of neutralisation/hydrolysis gives a product containing about 55-65% alkene sulphonates and 25-35% hydroxy alkane sulphonates and 5-15% disulphonates. The C(l,3) sultones and D(l,4) sultones have virtually disappeared in the plug flow reactor with a residence time of 30 minutes at HO C. The ratio between initial and final concentration of delta (1,4) sultones will be ... 

As a check, the sum of the alkene sulphonates and hydroxyalkane sulphonates in mol/1 may be determined on the original sample by titration with benzethonium chloride. The result includes any 2-hydroxy-alkane sulphonate, which is not converted to the sultone by the acid treatment described, and so may differ slightly from the sum of the... 

A fourfold excess of lithium in ethylamine is effective in reducing methane-sulphonates of 2-hydroxy-nitriles to olefins, which contain only small amounts of the alkanes (Scheme 16). °...
