Environment-friendly N-tertiary butyl-2-benzothiazolsulfone amide (NS) synthesizing technology

The invention discloses an environment-friendly N-tertiary butyl-2-benzothiazolsulfone amide (NS) synthesizing technology which comprises the steps: (1) preparing dibenzothiazyl disulfide MBTS (DM); (2) preparing N-tertiary butyl-2-benzothiazolsulfone amide (TBBS or NS). The environment-friendly N-tertiary butyl-2-benzothiazolsulfone amide (NS) synthesizing technology disclosed by the invention has the advantages that hydrogen peroxide without pollution to the environment is utilized as an oxidizing agent; methylbenzene and water are immiscible and are easy to separate; tert-butylamine in a water phase can be extracted by the methylbenzene, and a tert-butylamine recovery rate is improved; a purity of NS can be as high as 99% or more, and a whole yield can be as high as 97% or more. 本发明是种环保型N-叔丁基-2-苯并噻唑次磺酰胺(NS)合成工艺，包括的步骤有：(1)制备二硫化二苯并噻唑MBTS(DM)；(2)制备N-叔丁基-2-苯并噻唑次磺酰胺(TBBS或NS)。本发明所述的种环保型N-叔丁基-2-苯并噻唑次磺酰胺(NS)合成工艺，优点在于氧化剂采用对环境无污染的双氧水；甲苯与水不互溶，易分离；甲苯可萃取水相中的叔丁胺，提高叔丁胺的回收率；NS纯度高达99％以上，整体收率高达97％以上。
