2% 2C6-dinitrotoluene-4-formic acid is an organic compound. Its physicochemical properties are as follows:
In terms of concept, this compound is a light yellow crystalline substance, which is stable at room temperature and pressure. Regarding the melting point, it is between 180-182 ° C. At this temperature, it melts from a solid state to a liquid state. Its boiling point is higher, and it may decompose before reaching the boiling point under normal pressure, so accurate boiling point data are rare.
In terms of solubility, it is slightly soluble in water, because water is a polar solvent, and the polar compound is weak. According to the principle of similar miscibility, it is difficult to dissolve in water. However, it can be soluble in organic solvents such as ethanol, ether, acetone, etc. Such organic solvents have moderate polarity and are similar to the structure of the compound, so they can be mutually soluble.
Stability, stable at room temperature and pressure. However, it should be noted that it contains nitro groups, which are strong electron-absorbing groups, causing the compound to have certain oxidation and potential explosiveness. When heated, rubbed or exposed to an open flame, it may react violently and even explode.
Chemical activity, because it contains carboxyl groups and has carboxylic acid commonality, it can neutralize with bases to form corresponding carboxylic salts and water; it can also react with alcohols under the catalysis of concentrated sulfuric acid to form esters and water. At the same time, it contains nitro groups, which can be reduced to amino groups under specific conditions, such as under the action of metals and acids.
