Application Of Potassium Methoxide Solution
Potassium methoxide can be used:
- As a methoxylating agent for methoxylation of bromo- and mesyloxyalkanes in the presence of an ionic liquid.
- As a catalyst for the synthesis of dimethyl carbonate and methyl formate.
- As a catalyst for the transesterification of sunflower oil for the production of biodiesel.
Potassium Methoxide Formula and Molecular Structure
Chemically, the potassium methoxide formula is CH₃OK, consisting of a potassium ion (K⁺) and a methoxide ion (CH₃O⁻). It is the potassium salt of methanol and is highly reactive with water and moisture. The potassium methoxide molecular weight is 70.12 g/mol, which is useful when calculating precise dosages for reactions.
Density and Physical Properties
In terms of physical properties, the potassium methoxide density depends on whether it is in pure solid form or in methanol solution. For example, solid potassium methoxide has a density of around 1.13 g/cm³, while a 25–35% potassium methoxide solution in methanol will have a slightly lower density due to the solvent.
Storage and Safety Considerations
When using potassium methoxide solution, it's important to store it in airtight containers under inert gas to prevent degradation from moisture and carbon dioxide in the air.
Industrial Applications and Key Takeaways
By understanding the potassium methoxide density, potassium methoxide formula, potassium methoxide in methanol properties, potassium methoxide molecular weight, and the different specifications of potassium methoxide solution, industries can ensure safer application of reagent.
