The synthesis method of 5,7-dichloro-8-quinolinyl benzoic acid, although the ancient book "Tiangongkai" does not directly mention the synthesis of this specific compound, its traces can be found from the traditional chemical process ideas.
To synthesize this compound, you can start from the selection of raw materials and reaction path planning. In traditional chemistry, materials are often selected according to material characteristics and reaction laws. For this compound, chlorine, quinolinyl and benzoic acid-related raw materials are required.
First, chlorine-containing halides, such as chloroalkanes or chloroaromatics, can be found. The chlorine atom has high activity and can be introduced into the target molecule through substitution reaction. Furthermore, quinoline compounds can be prepared by a series of reactions such as condensation and cyclization of the corresponding aromatic amines and aldodecanones. The benzoic acid part can be obtained from benzaldehyde through oxidation reaction.
In terms of reaction path, the chlorine-containing raw material can be combined with the quinoline-based raw material according to the principle of substitution reaction, or under appropriate catalyst, solvent and temperature conditions, the chlorine atom can replace the hydrogen atom at a specific position on the quinoline group to construct the 5,7-dichloro-8-quinolinyl moiety. Subsequently, this intermediate is reacted with benzoic acid derivatives, or esterified or acylated, so that the two can be connected to form 5,7-dichloro-8-quinolinyl benzoic acid.
Or first synthesize the main body containing benzoic acid, and then gradually introduce 5,7-dichloro-8-quinoline group. During synthesis, attention should be paid to the control of reaction conditions, such as temperature, pH and reaction time, because it has a great impact on the reaction rate, product purity and yield. Although the ancient method is different from the modern synthesis technology, the basic chemical principles are similar, and the synthesis method can be explored according to this idea.

5% 2C7-dinaphthalene-8-sulfobenzoic acid light has many points to pay attention to during use.
First, when storing, choose a dry, cool and well-ventilated place. This is because if the substance is placed in a humid environment, it is prone to moisture and deterioration, which affects its performance; and a high temperature environment may cause it to undergo chemical reactions, which will reduce its efficacy.
Second, you must be careful when using it. Because it has certain chemical activity, you need to wear suitable protective equipment during operation, such as gloves, goggles, etc., to prevent contact with the skin and eyes and cause damage. If you contact it inadvertently, you should immediately rinse with plenty of water and seek medical treatment according to the specific situation.
Third, the use process needs to strictly follow the established operating procedures. Different uses have different requirements for the dosage of the substance, reaction conditions, etc., and must not be changed at will. And during use, close attention should be paid to the reaction phenomenon. If there is an abnormality, the operation should be stopped immediately to investigate the cause.
Fourth, waste treatment should not be ignored. Do not discard the used residue or waste after reaction at will. It needs to be sorted and collected according to relevant regulations and handed over to professional institutions for treatment to avoid pollution to the environment.
In conclusion, when using 5% 2C7-dinaphthalene-8-sulfobenzoic acid light, every step from storage, operation to waste disposal needs to be treated carefully to ensure safe use and give full play to its effectiveness.
