Melting point of dimethoxybenzene Rating: 8,9/10 1480 reviews

The melting point of a substance is the temperature at which it transitions from a solid to a liquid. Dimethoxybenzene, also known as anisole, is a colorless liquid with a sweet, pleasant aroma. It has a melting point of -67.6 degrees Celsius (-89.7 degrees Fahrenheit).

Anisole is a member of the aromatic compound family, which are known for their stable structures and high melting points. This is due to the presence of multiple aromatic rings in the molecule, which are held together by strong bonds. These bonds require a significant amount of energy to break, resulting in a high melting point.

The melting point of a substance can be determined through a process called differential scanning calorimetry (DSC). In this method, a sample of the substance is heated at a constant rate while the temperature is monitored. The temperature at which the substance transitions from a solid to a liquid is recorded as the melting point.

Anisole has a relatively low melting point compared to other aromatic compounds due to the presence of two methoxy groups (-OCH3) on the benzene ring. These groups are electron-withdrawing, which means they can stabilize the negative charge on the aromatic ring. This stabilization reduces the energy needed to break the bonds in the molecule, leading to a lower melting point.

In addition to its low melting point, anisole has a number of other unique properties. It is highly flammable and has a low flash point, making it potentially hazardous in certain situations. It is also highly soluble in many organic solvents, such as ethanol and acetone, but is poorly soluble in water.

Anisole has a variety of industrial uses, including as a solvent for paints and coatings, as a flavor and fragrance ingredient, and as a starting material in the synthesis of other chemicals. Its sweet, pleasant aroma has made it a popular choice in the fragrance industry, and it is often used to mask unpleasant odors.

Overall, the melting point of anisole is an important physical property that determines its behavior at different temperatures. Understanding its melting point, as well as its other properties, is important for its safe handling and use in various applications.

Study results If more than one value is available, results are displayed as concatenated distinct values, ordered from most to least commonly provided, with the percentage of provided values appended. Study results If more than one numerical result is available per endpoint, the range of results min-max and range of experimental conditions will be presented RANGE method. Study results Displayed are the RANGES of min — max of the PRIORITISED value s within the five highest priority groupings of provided data. If so, the data provided is not processed for the Brief Profile. Therefore, data has to fit the format and aggregation logic that is used for the Brief Profile. In most cases, impurities constitute less than 10% of the substance.
