Аннотация
Simple urea-based chemicals have been used in the textile industry for "ironing-free clothes" for decades. 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 "triazine" 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.
