• 解毒与急救

立即急救：确保已经进行了充分去污。如果患者停止呼吸，开始人工呼吸，最好使用需求阀复苏器、气囊面罩装置或口袋面罩，按训练进行操作。根据需要执行心肺复苏。立即用缓慢流动的水冲洗受污染的眼睛。不要催吐。如果发生呕吐，让患者前倾或置于左侧（如果可能的话，头部向下）以保持呼吸道畅通，防止吸入。保持患者安静，维持正常体温。寻求医疗帮助。/酮体及相关化合物/

Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR as necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. /Ketones and related compounds/

Consider administering a beta agonist such as albuterol for severe bronchospasm ... . Monitor cardiac rhythm and treat arrhythmias if necessary ... . Start IV administration of D5W /SRP: "To keep open", minimal flow rate/. Use 0.9% saline (NS) or lactated Ringer's (LR) if signs of hypovolemia are present.

  heterogeneous catalytic method for the methylation of C–H bonds in alcohols, ketones, and indoles with methanol under oxidant-free conditions using a Pt-loaded carbon (Pt/C) catalyst in the presence of NaOH is reported. This catalytic system is effective for various methylation reactions: (1) the β-methylation of primary alcohols, including aryl, aliphatic, and heterocyclic alcohols, (2) the α-methylation

  一种通用，选择性和可循环利用的非均相催化方法，是在无氧化剂的条件下，使用载有Pt的碳（Pt / C）催化剂在NaOH的存在下，用甲醇在醇，酮和吲哚中的C–H键进行甲基化的方法是报告。该催化体系对各种甲基化反应均有效：（1）伯醇（包括芳基，脂肪族和杂环醇）的β-甲基化；（2）酮的α-甲基化；（3）选择性C3-吲哚的甲基化。反应由借氢机制驱动。反应开始于将醇脱氢得到醛，然后将其与亲核试剂（醛，酮或吲哚）进行缩合反应，然后通过Pt–H物种将缩合产物氢化以生成所需的醛。产品。在这项研究中探讨的所有甲基化反应中，Pt / C催化剂的周转率均比以前报道的其他均相催化体系高得多。而且，证明了如在不同金属表面上的密度泛函理论计算所揭示的，Pt的高催化活性可以根据氢在金属表面上的吸附能而合理化。
