Предлагаетс способ получени солей 3-оксисульфолан - 4 - сульфокислот реакцией 3,4эпоксисульфолана с насыщенным водным раствором бисульфита соответствующего металла при кип чении в течение 0,5-1 час.A method is proposed for the preparation of 3-oxysulfolan-4-sulfonic acid salts by the reaction of 3.4 epoxysulfolane with a saturated aqueous solution of a bisulfite of the corresponding metal at the boil for 0.5-1 hour.
Пример. В реактор, снабженный обратным холодильником, загружают 13,4 г 3,4эпоксисульфолана и 120 мл 40%-ного раствора бисульфита натри . Смесь кип т т в течение 30 мин. При этом вс окись сульфолаиа раствор етс . Смесь оставл ют на 15 час дл кристаллизации. Выпавщий осадок 19,3 г (81%) представл ет собой натриевую соль 3-оксисульфолан - 4 - сульфокислоты.Example. 13.4 g of 3.4 epoxysulfolane and 120 ml of 40% sodium bisulfite solution are charged to a reactor equipped with a reflux condenser. The mixture is boiled for 30 minutes. In this case, all sulfolium oxide dissolves. The mixture was allowed to crystallize for 15 hours. The precipitation of 19.3 g (81%) is the sodium salt of 3-oxysulfolane-4-sulfonic acid.
