Potassium isopropoxide - Introduction
Potassium isopropoxide(Potassium isopropoxide) is a chemical substance whose chemical formula is (CH3)2CHO ^-K, which belongs to organic base salt.
Nature:
1. appearance: Potassium isopropoxide is colorless to light yellow liquid, can also be solid form.
2. solubility: Potassium isopropoxide soluble in organic solvents such as ethanol and ether solvents, but difficult to dissolve in water.
3. stability: easy to damp, should be stored in a dry place.
Use:
1. As a catalyst for organic synthesis reactions, it is widely used in esterification reactions, etherification reactions, alcohol dehydration reactions and other reactions.
2. In organic synthesis, Potassium isopropoxide is commonly used as precursor to prepare metal isopropoxylation reagents, such as aluminum isopropoxide.
3. can be used as a catalyst in the synthesis of certain drugs.
4. for the preparation of certain metal organic compounds.
Preparation Method:
Potassium isopropoxide can be synthesized:
In the organic solvent, add isopropyl alcohol and then slowly add potassium metal. After completion of the reaction, the product is obtained by a freezing precipitation method or a condensation method.
Safety Information:
1. Potassium isopropoxide is easy to react with water to generate isopropanol and potassium hydroxide, so contact with water should be avoided.
2. use should wear protective gloves, goggles and protective clothing.
3. should be used in a well-ventilated place to avoid inhalation of Potassium isopropoxide vapor.
4. If skin contact occurs, rinse immediately with plenty of water and seek medical assistance.
5. Potassium isopropoxide should be away from fire and oxidant, stored in a dry, cool place.
