摘要

几十年来，纺织工业一直在使用简单的尿素基化学品来制作“免熨烫衣服”。最常用的化学品之一是1,3-二甲基-4,5-二羟乙基脲（DMDHEU），它由尿素、乙二醛和甲醛组成。DMDHEU和相关化学品被认为是安全和无害的。因此，我们合成了这些化合物，并研究了它们作为H2S清除剂的性能，以替代目前海上工业中使用的“三嗪”化合物。几种衍生物很容易获得，我们已经用拉曼光谱评估了它们的清除性能。这项研究揭示了这类化合物在类似于三嗪基清除剂的条件下清除H2S，并深入了解了所需的结构要求。

Urea Derivatives as H₂S Scavengers.

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.

期刊介绍： Molecules (ISSN 1420-3049, CODEN: MOLEFW) is an open access journal of synthetic organic chemistry and natural product chemistry. All articles are peer-reviewed and published continously upon acceptance. Molecules is published by MDPI, Basel, Switzerland. Our aim is to encourage chemists to publish as much as possible their experimental detail, particularly synthetic procedures and characterization information. There is no restriction on the length of the experimental section. In addition, availability of compound samples is published and considered as important information. Authors are encouraged to register or deposit their chemical samples through the non-profit international organization Molecular Diversity Preservation International (MDPI). Molecules has been launched in 1996 to preserve and exploit molecular diversity of both, chemical information and chemical substances.
