Abstract
Inventia se refera la un procedeu de obtinere a 3-clorpropansulfonatului de sodiu, înlocuitor al agentului de sulfopropilare, propansulfana, un puternic cancerigen, utilizat pentru obtinerea de schimbatori de ioni celulozici sau pe baza de geluri de dextran reticulat. Alcoolul alilic este transformat în 3-hidroxipropansulfonat de potasiu prin aditia ionului bisulfit. Prin actiunea clorurii de tionil în prezenta catalizatorului dimetilformamida asupra srii de potasiu, se obtine 3-clorpropansulfoclorura. Prin hidroliza în mediu apos a sulfoclorurii si neutralizare rezulta 3-clorpropansulfonatul de sodiu. Randamentul global fata de alcoolul alilic este de 48%.
