The preparation method of quinoline, 1, 2, 3, 4-tetrahydro- has been known for a long time, and is described in detail below.
First, quinoline is used as the starting material, and the method of catalytic hydrogenation is used. Choose a suitable catalyst, such as a noble metal catalyst, and make hydrogen react with quinoline under appropriate temperature and pressure conditions. If the temperature is properly controlled, or in a specific range, the pressure is also adjusted moderately, then hydrogen can be gradually added to the unsaturated bond of quinoline, resulting in 1, 2, 3, 4-tetrahydroquinoline. In this process, the activity and selectivity of the catalyst are the key. If the activity is high, the reaction rate is fast, and if the selectivity is good, there are few side reactions, and the purity of the product is guaranteed.
Second, through the organic synthesis path. A specific intermediate can be prepared first, with nitrogen-containing compounds and hydrocarbons with suitable functional groups as starting materials, through a series of chemical reactions, such as nucleophilic substitution, condensation, etc., to construct an intermediate with a structure similar to 1,2,3,4-tetrahydroquinoline. Subsequently, this intermediate is subjected to a reduction reaction, such as metal hydride and other reducing agents, to reduce specific unsaturated bonds, and finally obtain 1,2,3,4-tetrahydroquinoline. This path requires precise control of the reaction conditions, and the order and reaction conditions of each step will affect the yield and purity of the final product.
Third, there is a preparation method using natural products as the starting point. Some natural products may contain components related to the structure of 1, 2, 3, 4-tetrahydroquinoline, and the target product can also be prepared through extraction, separation, modification and other steps. However, this method is often subject to the source and content of natural products, and the extraction and modification process is often complicated, requiring fine operation and high-end technology.
All these preparation methods have their own advantages and disadvantages. In fact, they need to be selected according to the actual needs and conditions, so as to efficiently prepare 1, 2, 3, 4-tetrahydroquinoline.

Quinoline, 1, 2, 3, 4-tetrahydro-, is a class of organic compounds. Its physical properties are particularly important, and it is related to many uses and characteristics of this compound.
In terms of color state, 1, 2, 3, 4-tetrahydroquinoline is often colorless to light yellow liquid, and it has a flowing state. It can be seen in ordinary light that its transparent quality is slightly glossy, just like the early gathering of morning dew, clear without losing charm. < Br >
Smell the smell, which seems to have a special aromatic aroma, but it is not as rich as orchid, nor as sweet as cinnamon. It is a unique organic aromatic smell. At first, it is slightly pungent, but gradually smelling it can sense its unique charm. If placed in a ventilated place, its gas can gradually disperse in the air.
When it comes to the boiling point, the boiling point of this compound is about 195-200 ° C. When the heating method is applied and the temperature gradually rises to nearly 200 ° C, it can be seen that it gradually transforms from a liquid state to a gaseous state, just like a cloud rising. This boiling point characteristic is crucial in separation and purification processes, so it can be effectively separated from the mixture. < Br >
The number of melting points is about -12 ° C. When the outside temperature drops to around -12 ° C, the originally flowing liquid gradually solidifies, as if time is static, its state changes from liquid to solid, and the molecular arrangement becomes orderly from disorder. The nature of this melting point needs to be carefully considered during storage and transportation.
Above the density, the density of 1,2,3,4-tetrahydroquinoline is slightly larger than that of water, about 1.06g/cm ³. If it is placed in the same place as water, it can be seen that it sinks underwater, such as stone entering water. The difference in density can be used as an important basis for judging in some experiments or industrial operations of liquid-liquid separation. In terms of solubility, it is soluble in many organic solvents, such as ethanol, ether, etc., just like fish get water, and the two can be mixed into a uniform state; however, the solubility in water is poor, and the two meet, such as oil floating in water, distinct, this solubility characteristic also affects its reaction and application in different media.
