“…Different authors have used a nucleophilic scavenging agent, synthesis ureas, thioureas amides, sulfonamides, and carbamates to remove the excess isocyanate, isocyanide, isociamide, acyl chloride, or sulfonyl chlorides [10,11]. Scavenger resins, depending on their structure and functionalities, can be used for scavenging of: anhydride [12], acid chloride [13], amines [14,15], esters, epoxides [16,17], aldehydes and ketones [18,19], miscellaneous compounds [20], for metal removal from a reaction mixture [21], functionalized with gold nanoparticles [22], for efficient removal of environmental pollutants [23], in the field of culture heritage to clean surfaces for art conservation and restoration [24], preventing paper documents [25] and many others [26]. The majority usually used method of forming HIPEs is through the slow addition of a porogen (non-continuous phase) to the continuous phase with mixing, although other methods can be used [27].…”

The developments of monolithic materials rapidly in nowadays hold an impressively strong position in separation science as well as in other areas of chemistry. In this research are presented functionalization of PolyHIPE monolithic materials by tris(2-aminoethyl) amine. Monolithic polymer supports and scavengers were synthesized via nucleophilic displacement of chlorine in poly(4-vinyl benzyl chloride-co-divinylbenzene) as PolyHIPE materials. Porous copolymers of DVB/DVB were prepared by emulsion templating using high internal phase emulsions (HIPEs) as precursors for monoliths. The properties of the final products synthesized were functionalized with an amino group, at a different ratio of amine/chloromethyl groups, in different time refluxed were explored. PolyHIPE functionalized with tris(2-aminoethyl)amine to yield a product with high degrees of conversion. The extent of the functionalization reactions was investigated by a range of qualitative and quantitative techniques: FTIR, CHN analysis, potentiometric measurements, and (BET) measurements have been performed.

“…Polymer-bound sulfonylhydrazide has been prepared from commercial sulfonic acid resin through a straightforward, one-step synthetic route avoiding chlorosulfonic intermediates [11]. This sulfonylhydrazide resin has found an application as a scavenging agent in winemaking, and an efficient recycling protocol of the used supports has also been established.…”

“…Carbonyl compounds, such as aldehydes and ketones, are present in essential oils from plant extracts. − When these materials appear in tiny amounts, their isolation/characterization may present great experimental difficulties . Sulfonyl hydrazine supported reagents are used for capturing aldehydes and ketones forming sulfonyl hydrazones. − The syntheses for producing this type of supported reagents are time-consuming and require high-cost or dangerous reagents.…”

A low-cost isoniazid-based scavenger resin was previously prepared and successfully used to capture aldehydes and ketones in solution by using a batch approach. The present work compares batch and continuous processes in relation to the preparation of the scavenger resin and the effectiveness of cyclohexanone scavenging. The batch preparation of the resin proved to be the better choice because the resin produced in the continuous flow suffered deformation on its surface that prevented access to the active sites in the internal porous polymer matrix. Conversely, the continuous-flow approach presented higher capturing yields than the batch. The optimized scavenging process was successfully used to remove formaldehyde present in a solution and the carbonyl compounds present in an ethanolic extract of Cymbopogon citratus.
