Can dimethylformamide be stored in plastic bottles? Or is it better to store in glass bottles?
Yes if after mixture it is kept for about 10mins,before it can be stored in a plastic bottle
Dimethylformamide (DMF) is a versatile organic solvent commonly used in various industries. When it comes to storing DMF, it is generally recommended to use glass bottles rather than plastic bottles. Here's why:
1. Compatibility: DMF has a high compatibility with many plastics, including polyethylene and polypropylene, commonly used in plastic bottles. However, prolonged storage of DMF in plastic bottles can lead to gradual absorption of DMF by the plastic material, which can result in deterioration of the plastic and potential leaching of additives or impurities from the plastic into the solvent.
2. Permeation: While DMF does not significantly permeate through most common plastics, over time, it can slowly diffuse through certain plastics and cause a loss of volume. This can affect the concentration and performance of DMF.
3. Chemical reactions: Some plastic materials can undergo chemical reactions or degradation when exposed to DMF. This can further impact the purity and stability of the solvent.
Considering these factors, glass bottles offer several advantages for storing DMF:
1. Inertness: Glass is chemically inert and does not react with or absorb DMF. This ensures that the stored DMF remains pure and uncontaminated.
2. Impermeability: Glass is impermeable to DMF, preventing any loss of solvent volume or concentration. This helps maintain the effectiveness and consistency of the stored DMF.
3. Transparency: Glass bottles allow easy inspection of the solvent and can prevent any visual contamination. It also enables accurate measurement and avoids potential dosage errors.
In summary, although DMF can be stored in plastic bottles to some extent, it is generally recommended to use glass bottles for long-term storage, especially to maintain the purity and stability of the solvent.
