  Abstract Acetalation of formaldehyde (HCHO) with dialkyl formal or aliphatic alcohol to prepare polyoxymethylene dialkyl ethers (RO(CH2O)nR, n ≥ 1) catalyzed by Bronsted-acidic ionic liquids has been developed. The correlation between the structure and acidity activity of various ionic liquids was studied. Among the ionic liquids investigated, 1-(4-sulfonic acid)butyl-3-methylimidazolium hydrogen sulfate

  摘要 已开发出在布朗斯台德酸性离子液体的催化下，甲醛 (HCHO) 与二烷基缩甲醛或脂肪醇的乙酰化反应制备聚甲醛二烷基醚 (RO(CH2O)nR，n ≥ 1)。研究了各种离子液体的结构与酸度活性之间的相关性。在所研究的离子液体中，1-(4-磺酸)丁基-3-甲基咪唑硫酸氢盐([MIMBs]HSO4)在二乙氧基甲烷(DEM1)与三恶烷的反应中表现出最好的催化性能。以[MIMBs]HSO4为催化剂，研究了离子液体负载量、DEM1与HCHO摩尔比、反应温度、压力、时间和反应物来源对催化反应的影响。在 n([MIMBs]HSO4):n(DEM1):n(HCHO) = 1:80:80、140 °C、4 h 的最佳条件下，HCHO 的转化率和 DEM2-8 的选择性分别为 92.6% 和 95.1%。[MIMBs]HSO4 催化剂可以很容易地分离和重复使用。提出了 [MIMBs]HSO4 催化性能的可行机制。

  The state of general anesthesia (GA) is essential to many surgical and medical procedures. This state is characterized by loss of consciousness, deep analgesia and suppression of movements. GA is rarely achieved with a single drug, usually requiring the combination of various pharmacological agents. Each drug can interact with one or more molecular targets affecting neuronal excitability and synaptic transmission in multiple regions of the CNS. Agonists of the μ-opioid receptor are commonly used in GA to cause analgesia, but not to induce or maintain loss of consciousness or movement suppression. Additionally, agonists of the μ-opioid receptor can cause serious unwanted side effects, e.g. respiratory depression. The present invention provides alternative combination products based on K-opioid receptor agonists. These combination products unexpectedly induced loss of consciousness, and were able to achieve and maintain GA. Furthermore, the combination products suppressed pain perception without the need of a μ-opioid receptor agonist. The combination of Salvinorin A, a selective κ-opioid receptor agonist, with Diazepam or Medetomidine surprisingly led to rapid consciousness, deep analgesia and movement suppression. This combination was found to effectively induce and maintain a state of general anesthesia.
