一般描述

在形状选择性沸石存在下,甲醇向C2-C10烃的热化学型转化已被报道。它通过钌吸附原子在Ru-Pt催化剂体系上的氧化已被提出。
甲醇是一种可在CuO / ZnO / Al2O3催化剂存在下由合成气合成的有机溶剂。因其具备高H/C比、低烟灰产生倾向、相对低的重整温度并在室温下以液相状态形式存在,它是燃料电池技术中的一种理想氢源。在直接甲醇燃料电池(DMFC)中,甲醇经空气氧化而发电。通过MTO(甲醇-烯烃)工艺由甲醇所形成的烯烃(乙烯或丙烯)可替代石油和天然气用于烃燃料的生产。

应用

甲醇(MeOH)已用于胚胎组织的整体免疫荧光研究。
它还可用于以下研究:
  • 骨髓单核细胞的克隆形成单位-成纤维细胞检测。
  • 作为通过反相HPLC对胶霉毒素进行预估而制备曲霉菌丝提取物的溶剂。
  • 免疫荧光研究。
  • 用离子对反相HPLC对核苷酸及其分解产物进行分离的洗脱液的组成成分。
甲醇可在反相液相色谱中作为一种移动相使用。

  1. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  2. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  3. Who do I contact about larger solvent volume needs?

    Email us at labessentials@sial.com or visit Sigma-Aldrich Fine Chemicals for development and manufacturing-scale inquiries: safcglobal@sial.com

  4. How do I know what packaging options are available for a solvent?

    The Solvent Center gives you the ability to review all the specifications associated with our solvent packaging. This includes physical dimensions, closure types, dispensing methods, UN/DOT Rating as well as solvent compatibility. Visit the Solvent Center.

  5. Who do I contact if I need a solvent blend, which you do not carry?

    Email us at labessentials@sial.com. For a complete listing of all our Solvent blends, visit the Solvent Center

  6. The dispensing of solvents provides some challenges due to the number of container options available. What dispensing options are available for each container?

    The Sigma-Aldrich Solvent Center provides numerous dispensing options for each container type. For a complete listing of all our dispensing options, visit the Solvent Center.

  7. Which solvent grade should I be using for my application?

    Sigma-Aldrich Solvent Applications Table gives a guideline to common applications and the appropriate solvent grades.  Visit: Solvents

  8. What are the options for drying solvents? 

    Sigma-Aldrich offers a full range of high-purity solvents with extremely low water levels specifically manufactured for moisture sensitive Organic and Biotech applications.  Sigma-Aldrich also carries various drying agents such as molecular sieves, which are typically compatible with organic solvents.

  9. What apparatus do you recommend for HPLC solvent filtration?

    The Sigma-Aldrich Vacuum Filtration Assembly gives you all the components you need including: funnel top, fritted glass funnel support, filtration flask, aluminum clamp, and silicone stopper.  The Acrodisc Syringe Filters offer high quality filtration for analytical samples, certified for HPLC to ensure low extractable and available in a broad range of membranes to meet sample compatibility requirements.

  10. Can you recommend a Solvent Extractor for organics from aqueous solution?

    Solvent extractors are often used for the quantitative extraction of organics from aqueous solutions and separations in immunoassays. The MIXXOR system has been applied successfully in many laboratory solvent extraction operations and is ideal for the rapid screening of alternative solvents for specific extraction problems.

<i>In Situ</i> Hybridization of Whole-Mount Mouse Embryos with RNA Probes: Hybridization, Washes, and Histochemistry. This is a protocol describing how to perform in situ hybridization on whole mouse embryos. Here we describe the hybridization procedure, and the localization of the DIG-labeled RNA using a conjugate of anti-DIG Fab antibody and calf intestinal alkaline phosphatase. Enzyme activity of the reporter is detected by a color reaction, resulting in the formation of a water-insoluble purple/blue precipitate. Manipulating the Mouse Embryo - Third Edition
