2-Phenyl-7-chloroquinoline is an organic compound with unique physical properties that has attracted much attention in the fields of organic synthesis and medicinal chemistry. The following are its main physical properties:
1. ** Properties **: Usually solid, due to the molecular structure containing benzene and quinoline rings, the intermolecular force is strong, so it is stored in a solid state at room temperature and pressure. This solid state property is convenient for storage and transportation, and it also provides convenience during chemical reaction operations. It can be accurately weighed and used.
2. ** Melting point **: Melting point is about 150-155 ° C. Melting point is an important indicator for identification and purity judgment. The compound has a specific melting point. If it contains impurities, the melting point may drop and the melting range is widened. By measuring the melting point, its purity can be preliminarily determined, providing a basis for quality control.
3. ** Boiling point **: The boiling point is high, about 380-390 ° C. The high boiling point is due to the existence of van der Waals forces 、π - π stacking between molecules, etc., so that more energy is required for molecular separation. This characteristic makes it stable under high temperature conditions. It can be used as a stable reactant or intermediate in chemical processes that require high temperature reactions.
4. ** Solubility **: It is difficult to dissolve in water. Due to the small polarity of the molecule, the force between it and water molecules is weak. But it can be soluble in some organic solvents, such as dichloromethane, chloroform, N, N-dimethylformamide (DMF), etc. This solubility characteristic is conducive to the selection of suitable solvents for reaction in organic synthesis, and it is also convenient to separate and purify from the reaction system.
5. ** Density **: The density is about 1.3 g/cm ³. The density data is of great significance in terms of solution preparation, reaction system volume-quality conversion, etc., which helps to accurately measure the reactants and products and ensure the accuracy of experiments and production.
6. ** Appearance and color **: The appearance is often white to light yellow crystalline powder. The color and crystal form are affected by the preparation method and purity. By observing the appearance and color, the quality and purity can be preliminarily evaluated. It provides an intuitive basis for preliminary judgment in production and experiment.

To prepare 2-phenyl-7-chloroquinoline, the method is as follows:
First, all raw materials must be prepared, such as appropriate aromatic amines, chlorine-containing aromatic aldoxides and other auxiliary reagents. O-aminobenzoic acid derivatives and p-chlorobenzaldehyde are often used as starting materials.
Before the reaction, the reaction system should be kept at a suitable temperature and pressure, and it should be clean and anhydrous. The reaction is usually carried out in organic solvents, such as ethanol, toluene, etc., because it can dissolve the raw materials well and help the reaction go smoothly.
At the beginning of the reaction, the raw materials are put into the reactor in a specific ratio, and the reaction is catalyzed by a specific catalyst. Concentrated sulfuric acid, Lewis acid, etc. are often used as catalysts, which can accelerate the reaction process and reduce the activation energy of the reaction. If concentrated sulfuric acid is used as a catalyst, the dosage should be carefully controlled, because too much acid or side reactions may occur.
When reacting, continue to stir to mix the materials evenly to make the reaction sufficient. Temperature control is essential. If the temperature is too high or the product is decomposed, the reaction will be delayed if it is too low. Generally speaking, the reaction temperature may be maintained at 80-120 ° C, fine-tuned according to the specific reaction.
After the reaction is completed, the product should be separated and purified by an appropriate method. The reaction solution is usually extracted by extraction with an organic solvent to enrich the product in the organic phase. Then it is further purified by column chromatography or recrystallization to obtain high purity 2-phenyl-7-chloroquinoline. During column chromatography, appropriate stationary phase and mobile phase are selected to effectively separate the product from impurities; during recrystallization, a suitable solvent is selected to dissolve the product in a hot solvent. After cooling, the crystallization precipitates, and the impurities remain in the mother liquor.
After these steps, pure 2-phenyl-7-chloroquinoline can be obtained. However, during the reaction process, fine operation and strict control of various conditions are required to obtain the ideal yield and purity.
