一般描述

氯仿是一种卤化烃,广泛用作各种制造和实验室程序中的溶剂和萃取剂。它可以通过甲烷或低氯化甲烷的氯化反应产生。此外,它还用于生产二氯羰基、α-三氯甲基甲醇和三氯硫代类羰基。

应用

氯仿可作为溶剂用于:
  • 通过 ω-十五内酯的酶催化开环聚合制备聚酯
  • 通过 Pd 催化的氯化物与芳基硼酸交叉偶联反应合成二芳基酮。
  • 通过 α-芳基亚硝基甲烷与氨基砜的对映和非对映选择性硝基-曼尼希反应合成β-硝基胺。
  • 通过狄尔斯-阿德尔反应合成螺融合二氢丙酮。氯仿和羰基氧间形成的氢键(CH-O)使羰基成为更强的异二亲试剂,从而提高了反应速率。

  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.
