1. 3 - propane sulfonic acid lactone preparation method (by machine translation)

The invention discloses 1, 3 - propane sultone preparation method, steps are as follows: (1) to the catalyst and sodium bisulfite as raw materials, deionized water as the medium, in the initiator catalytic addition react to generate the 3 - hydroxy c sodium sulfonate; (2) adding sulfuric acid to the reaction solution in the acidification, then distilled to remove the excessive water, adding anhydrous ethanol extraction and filtration, to obtain 3 - hydroxy propane sulfonic acid ethanol solution; (3) the 3 - hydroxy propane sulfonic acid ethanol solution of the first normal pressure distillation to remove the ethanol, and get the 1, 3 - propane sulfonic acid lactone; (4) is added to the distillation still in the sodium hydroxide aqueous solution to perform hydrolysis, then adding sulfuric acid acidified, then adding anhydrous ethanol extraction and filtration, to obtain 3 - hydroxy propane sulfonic acid ethanol solution, then remove ethanol from atmospheric distillation, and get the 1, 3 - propane sulfonic acid lactone. The above preparation method can reduce the reaction temperature, and the product of the molar yield high, fixed less waste, easily to obtain high-purity product. (by machine translation)

The mechanism of hydrolysis of 2-hydroxyethanesulfonyl chloride: the intermediacy of 1,2-oxathietane 2,2-dioxide (β-sultone)

The hydrolysis of 2-hydroxyethanesulfonyl chloride (1) has been investigated with the aid of kinetic and product analysis studies.The results are quantitatively consistent with the mechanism of hydrolysis shown in Scheme 1, the chief features of which are (a) formation of β-sultone (2) and its rapid further reaction (the major pathway), together with (b) a minor direct hydrolysis route.The kinetics of both the β-sultone formation and the direct hydrolysis shows two terms, one first order in 1 alone, and the other first order in hydroxide as well; the rates of the first- and second-order reactions are lowered by added sodium chloride.It is suggested (a) that the unimolecular β-sultone formation involves 1 in a complex with water (as in 9) and that the water acts as a general base in the cyclization to 2, and (b) the hydroxide-promoted reaction proceeds by cyclization of the conjugate base of 1 (i.e., 10).The unimolecular direct hydrolysis is regarded as a conventional hydrolysis of a sulfonyl chloride with attack of the water with general base assistence from a second water molecule.The hydroxide-promoted direct reaction in D2O leads to no uptake of deuterium, showing taht the reaction does not go by way of the sulfene, and a reaction by way of a six-membered cyclic transition state is tentatively proposed.Evidence is presented that the chloride ion rate suppression is not primarily due to reaction of β-sultone with Cl- to give back 1; the possible origins of the effect are discussed.Key words: sulfonyl chloride, 2-hydroxyethanesulfonyl chloride, β-sultone, kinetics of sulfonyl chloride hydrolysis, mechanism of sulfonyl chloride hydrolysis
