Quinoline-6-formonitrile is one of the organic compounds. Its physical properties are particularly important, related to the properties of this substance, the point of melting and boiling, the solubility and other characteristics.
First of all, its appearance, under room temperature and pressure, quinoline-6-formonitrile is often in a solid state, mostly white or white crystalline powder, which is determined by its intermolecular forces and arrangement. To the naked eye, the texture is fine and there are no obvious impurities.
In terms of melting and boiling point, quinoline-6-formonitrile has a high melting point, about [X] ° C. Because the molecule contains a conjugated system and a cyanyl group, the intermolecular force is strong, and more energy is required to make the molecule break free from the lattice binding, so the melting point is significant. The boiling point is also correspondingly high, about [X] ° C, reflecting its relative stability.
Solubility is also a key physical property. In organic solvents, quinoline-6-formonitrile shows a certain tendency to dissolve. For example, in common organic solvents such as dichloromethane, chloroform, N, N-dimethylformamide (DMF), etc., it has good solubility. Due to the fact that the molecular structure of these organic solvents has a similar polarity to that of quinoline-6-formonitrile or can form a specific interaction with the cyanyl group, the solute is dispersed in the solvent system. However, in water, its solubility is very small, and the overall polarity of the quinoline-6-formonitrile molecule is limited, and although the cyanyl group has a certain polarity, it is difficult to form sufficient hydrogen bonds with water molecules to overcome its own intermolecular forces, so it is insoluble in the aqueous phase system.
In addition, the density of quinoline-6-formonitrile also has its own characteristics. Compared with water, the density is slightly higher than that of water, and the specific value is about [X] g/cm ³. This is due to the relative mass and spatial arrangement of carbon atoms, nitrogen atoms and other atoms in the molecule.
And its volatility is extremely low, because of its strong intermolecular force, it is not easy to escape from the liquid or solid surface to become a gaseous molecule, so it rarely evaporates at room temperature and pressure. This characteristic makes it relatively stable during storage and use, and it is not easy to lose or cause environmental pollution due to volatilization.

The chemical synthesis of quinoline-6-formonitrile is a very important topic in the field of organic synthesis. The details are as follows:
The selection of starting materials is often based on 6-haloquinoline and cyanide reagents. For example, 6-chloroquinoline, in this haloquinoline, the chlorine atom has active reactivity, which can provide an opportunity for the introduction of cyanide groups.
In the cyanide reaction step, the method of nucleophilic substitution can be used. 6-Chloroquinoline, cuprous cyanide, potassium cyanide and other cyanide reagents are mixed into suitable organic solvents, such as N, N-dimethylformamide (DMF), and an appropriate amount of base, such as potassium carbonate, is added to promote the reaction. Under heating conditions, cyanoanions will attack the check point of the chlorine atom of 6-chloroquinoline, causing nucleophilic substitution, and the chlorine atom will leave to form quinoline-6-formonitrile. In this process, DMF, as a polar aprotic solvent, can effectively dissolve the reactants, enhance the nucleophilicity of cyanoanions, and improve the reaction rate and yield.
Another approach is to use quinoline-6-carboxylic acid as the starting material. First, quinoline-6-carboxylic acid is converted into the corresponding acid chloride. If it reacts with dichlorosulfoxide, the hydroxyl group of the carboxylic acid is replaced by a chlorine atom to form quinoline-6-formyl chloride. This acid chloride is quite active, and then reacts with cyanide reagents, such as sodium cyanide, the chlorine atom of the acid chloride is replaced by a cyanide group, resulting in quinoline-6-formonitrile. Although this route is a little complicated, the selectivity of each step is good, which is helpful to obtain high-purity products.
After the reaction is completed, the separation and purification of the product is The method of column chromatography is often used to select suitable silica gel column and eluent, and according to the difference of the distribution coefficient between the product and the impurity in the stationary phase and the mobile phase, the separation of the two is achieved, and then the pure quinoline-6-formonitrile is obtained. In this way, the target compound quinoline-6-formonitrile can be obtained through raw material selection, reaction operation and product purification steps.
