Difference between diethyl ether and dimethyl ether

1. Based on my observations, basic definition and structure

Ether (Eth ether) and dimethyl ether (Diethyl ether) are both ethers, however there are obvious differences in their structures and applications. chemical structure

Ether consists of 1 molecule of ethane and 1 molecule of methoxyalkane, the molecular formula is C4H10O. Dimethyl ether consists of 2 molecules of ethane and 1 molecule of methoxyalkane, the molecular formula is C4H10O

2. I've found that Structural features

Ether molecular structure in the presence of a four-membered ring (cyclopropane-ring methyl structure), with high stability. You know what I mean?. Dimethyl ether structure in the two ethyl around a central methoxy arranged, so that the molecule has a substantial polarization.

2. physical characteristics comparison

boiling point

Ether has a boiling point of

34. 6°C, which is relatively high and is suitable as a solvent-based products. Dimethyl ether has a boiling point of only -

23. 2°C, the reduced boiling point making it frequently applied in high vacuum experiments and as a solvent-based products. Solubility

Ether in aquatic environments solubility is low, mainly with organic mixed consumption. Dimethyl ether has good solubility and is frequently applied in organic solvent-based products fields. Density

Ether has a density of about 0. I've found that Additionally 711g/cm³. Dimethyl ether has a density of 0. 718g/cm³, which is slightly higher than that of diethyl ether. But

3. chemical characteristics comparison

Flammability

Ether is flammable and when lit produces a yellow flame. Dimethyl ether while also flammable, however relatively safe, lit when the flame color is lighter. Stability

Ether in light and high temperature decomposition, will create acetaldehyde and carbon dioxide. Dimethyl ether is relatively stable and not easy to decompose, however prolonged exposure to the atmosphere still deserves our focus. chemical interaction characteristics

Ether in acidic or alkaline conditions easily hydrolyzed to create ethanol and acetic acid. And Dimethyl ether in acidic conditions isn't easy to decompose, often applied in organic reactions. And

4. selection and consumption

selection factor

Ether due to the boiling point is higher, frequently applied in the need to high boiling point solvent-based products occasions. Dimethyl ether due to the boiling point is low, easy to stratification characteristics, mostly applied to high vacuum experiments and organic solvent-based products applications. You know what I mean?. consumption field

Ether is broadly applied in organic chemical synthesis, extensive production of solvents, etc. But Dimethyl ether is mainly applied to experimental solvents, high vacuum systems, etc. And

5. Storage and Security

Storage

Ether needs to be kept in a cool, ventilated place, prevent direct sunlight. First Dimethyl ether due to the boiling point is low, often with the experimental equipment to carry, relatively easy to store. And Furthermore security Precautions

Ether flammable, operation should pay attention to fire. I've found that Dimethyl ether is flammable, however the relative ether is safer, the operation also need to pay attention to fire. Ether and dimethyl ether have signifiis able tot differences in structure, physical characteristics and chemical characteristics, and the choice of consumption should be judged according to the actual needs. And Specifically it's hoped that the analysis in this article is able to help you better understand and apply these two solvents.
