一般描述

叔丁醇钾溶液是一种强非亲核碱。它能够使碳和其他布朗斯台德酸去质子化。叔丁醇中的试剂溶液可以通过使无水醇与钾在氮气氛中反应来制备。

应用

叔丁二氧化钾溶液（t-BuOK）可用于：
  • 作为菜籽油与乙酸甲酯酯化反应的催化剂。
  • 在温和条件下促进N-苯基氨基酸衍生的酰化铵的 Sommelet-Hauser 重排反应。
  • 作为化学气相沉积法合成 KNbO3 铁电薄膜的金属有机前驱体。
  • 制备 3-钾肟基吡啶催化剂。
  • 作为强醇基试剂。

  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. Does the Tetrahydrofuran used to make Product 328650, Potassium tert-butoxide solution, contain a stabilizer?

    Yes, the THF contains about 0.025% butylated hydroxytoluene (BHT) as a stabilizer.

  4. What gloves can I use to work with Product 328650, Potassium tert-butoxide solution?

    We would recommend using Neoprene gloves such as Z402435, Z403407, Z402443, or Z402427.

  5. How do I remove Product 328650, Potassium tert-butoxide solution, from the Sure-Seal bottle?

    The Sure-Seal bottle has a septum held in place with a metal crimp cap. We would recommend removing the product by piercing the septum and withdrawing the liquid through a syringe to reduce the compound's exposure to air and moisture. We offer a line of non-coring syringe needles that are ideal for piercing septa.

  6. How should Product 328650, Potassium tert-butoxide solution, be stored?

    Room temperature storage is acceptable for this solution but we would recommend storing this product under nitrogen. The solution can decompose upon exposure to air or moisture. It also can absorb carbon dioxide from the air which will affect quality of the product.

  7. What is the purity of Product 328650, Potassium tert-butoxide solution?

    We do not perform overall purity testing on this solution. The product is prepared with reagent grade potassium tert-butoxide and then titrated  with hydrochloric acid to define the concentration during the quality control analysis.

  8. How do I find price and availability?

    There are several ways to find pricing and availability for our products. Once you log onto our website, you will find the price and availability displayed on the product detail page. You can contact any of our Customer Sales and Service offices to receive a quote.  USA customers:  1-800-325-3010 or view local office numbers.

  9. What is the Department of Transportation shipping information for this product?

    Transportation information can be found in Section 14 of the product's (M)SDS.To access the shipping information for this material, use the link on the product detail page for the product.
