One of the most used chemicals is 1,3-dimethylol-4,5-dihydroxyethyleneurea (DMDHEU), which consists of urea, glyoxal and formaldehyde. DMDHEU and related chemicals are considered safe and environmentally benign. We have therefore synthesized these compounds and studied their properties as H2S scavengers as alternatives to the \u201ctriazine\u201d compounds used in the offshore industry today. Several derivatives are easily available, and we have evaluated their scavenging properties using Raman spectroscopy. This study reveals that this class of compounds scavenges H2S under conditions similar to the triazine-based scavengers and gives insight into the structural requirements needed.<\/jats:p>","DOI":"10.3390\/molecules30040906","type":"journal-article","created":{"date-parts":[[2025,2,17]],"date-time":"2025-02-17T12:36:57Z","timestamp":1739795817000},"page":"906","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Urea Derivatives as H2S Scavengers"],"prefix":"10.3390","volume":"30","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3503-2857","authenticated-orcid":false,"given":"Asger Munk","family":"Koue","sequence":"first","affiliation":[{"name":"Department of Chemistry, University of Copenhagen, Universitetsparken 5, DK-2100 Copenhagen \u00d8, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Karolina Agata","family":"Szlek","sequence":"additional","affiliation":[{"name":"Section of Chemical and BioEngineering, Department of Chemistry and Bioscience, Aalborg University, Niels Bohrs Vej 8A, DK-6700 Esbjerg, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3145-7244","authenticated-orcid":false,"given":"Sergey","family":"Kucheryavskiy","sequence":"additional","affiliation":[{"name":"Section of Chemical and BioEngineering, Department of Chemistry and Bioscience, Aalborg University, Niels Bohrs Vej 8A, DK-6700 Esbjerg, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3120-7560","authenticated-orcid":false,"given":"Marco","family":"Maschietti","sequence":"additional","affiliation":[{"name":"Section of Chemical and BioEngineering, Department of Chemistry and Bioscience, Aalborg University, Niels Bohrs Vej 8A, DK-6700 Esbjerg, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4661-4895","authenticated-orcid":false,"given":"Christian Marcus","family":"Pedersen","sequence":"additional","affiliation":[{"name":"Department of Chemistry, University of Copenhagen, Universitetsparken 5, DK-2100 Copenhagen \u00d8, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,2,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"121448","DOI":"10.1016\/j.seppur.2022.121448","article-title":"Hydrogen Sulfide Capture and Removal Technologies: A Comprehensive Review of Recent Developments and Emerging Trends","volume":"298","author":"Pudi","year":"2022","journal-title":"Sep.
