Efficient preparation, uses, and recycling of a polymer-bound sulfonylhydrazide scavenger

Polymer-bound sulfonylhydrazide was prepared from commercial sulfonic acid resin through a straightforward, one-step synthetic route avoiding chlorosulfonic intermediates. The simplex self-directing optimization method was used to determine rapidly the ideal operating conditions under microwave irradiation. Polymer-bound sulfonylhydrazide has found an application as scavenging agent in winemaking therefore, this clean preparative approach is expected to be more acceptable by winemakers. An efficient recycling protocol of the used supports has also been established.
