To prepare 4-alkynyl-3- (triethylmethyl) naphthalene phenolic, the following ancient methods can be used.
First, naphthalene is used as the starting material. First, the naphthalene is alkylated by Fu-gram, and in the presence of an appropriate catalyst such as anhydrous aluminum trichloride, it is co-heated with triethylmethyl halogenated hydrocarbons to obtain 3- (triethylmethyl) naphthalene. In this step, attention should be paid to the ratio of the reaction temperature to the reactant. If the temperature is too high or the ratio is improper, it is easy to produce side reactions.
Then, the 3 - (triethylmethyl) naphthalene is brominated with bromine and a suitable catalyst, such as iron powder, at a mild temperature, and bromine atoms can be introduced at the 4 - position of the naphthalene ring to obtain 4 - bromo - 3 - (triethylmethyl) naphthalene. In this reaction, the trickle acceleration of bromine and the reaction time need to be precisely controlled to prevent over-bromination.
Then 4-bromo-3- (triethylmethyl) naphthalene is reacted with alkynyl-based reagents such as sodium acetylation. This step can form a carbon-carbon triple bond to obtain 4-alkynyl-3- (triethylmethyl) naphthalene. The reaction environment needs to be anhydrous and oxygen-free to avoid the decomposition of alkynyl-based reagents.
Finally, 4-alkyne-3- (triethylmethyl) naphthalene is heated with a suitable aldehyde-based reagent, such as N, N-dimethylformamide and phosphorus oxychloride under the catalysis of aluminum trichloride, and 4-alkyne-3- (triethylmethyl) naphthalene phenolic is obtained by introducing an aldehyde group into the phenolic hydroxyl ortho-position of naphthol through the Wellsmeier-Hack reaction.
Second, a suitable organic compound containing alkyne group and triethylmethyl group can also be used as the starting material to construct the naphthalene ring through a series of cyclization reactions. First, the alkynyl compound containing alkynyl and triethylmethyl groups is cyclized with benzene derivatives containing aldehyde and phenolic hydroxyl groups under the action of suitable transition metal catalysts such as palladium catalysts to directly construct the naphthalene ring skeleton, while retaining the appropriate positional relationships of alkynyl, triethylmethyl, phenolic hydroxyl and aldehyde groups. This route requires fine design of the structure of the starting material and strict reaction conditions. The type of transition metal catalyst, the choice of ligand and the reaction solvent all have a significant impact on the yield and selectivity of the reaction.

The physical properties of 4-3-trimethylquinoxaline nitrogen oxides are as follows:
This compound is mostly solid at room temperature, with a white or nearly yellowish color and a fine texture. It looks like a powder. Its melting point is about a specific range. In this temperature range, it gradually melts from a solid state to a liquid state. This temperature characteristic is crucial when identifying and purifying the substance.
In addition, its solubility also has characteristics. In common organic solvents, such as ethanol and acetone, there may be a certain degree of solubility. In ethanol, after moderate stirring, heating, etc., it can be partially dissolved into it to form a uniform dispersion system; in acetone, the degree of dissolution may vary, depending on the specific conditions. However, in water, its solubility is not good, and it is mostly suspended or sunk in the state of solid particles, making it difficult to dissolve with water.
Its density is slightly lighter than that of common inorganic substances. Placed in a specific measuring instrument, its density value can be accurately measured. This value is of great significance in considering the behavior of the substance in different environments, such as the distribution in the mixed system. And the color and shape of its appearance are also one of the important characteristics to identify the substance, which can provide an intuitive basis for subsequent chemical operations and research. The various physical properties are interrelated, and the application exploration in many fields such as chemical industry and medicine is an indispensable basic cognition.

4-Ming-3- (trimethylmethyl) benzaldehyde oxime has several precautions to be taken during storage and transportation.
One is related to storage. This compound should be placed in a cool, dry and well-ventilated place. Because the cool environment can reduce the risk of its chemical properties changing due to excessive temperature, drying can avoid its hydrolysis and other accidents, and good ventilation can avoid the accumulation of harmful gases. And it should be kept away from fires and heat sources to prevent ignition or promote violent chemical reactions. Furthermore, it should be stored separately from oxidizing agents, acids, alkalis, etc., and must not be mixed. Because of these substances or chemical reactions with 4-Ming-3- (trimethylmethyl) benzaldehyde oxime, it is dangerous. At the same time, the storage place should be equipped with suitable materials to contain leaks. Once there is a leak, it can be dealt with in time.
Second, as for transportation. Make sure that the packaging is complete and sealed before transportation. The integrity of the packaging can prevent it from leaking, and the sealing can block the influence of external factors. During transportation, make sure that the container does not leak, collapse, fall or damage. When driving, you should drive slowly to avoid severe bumps, vibrations and collisions, otherwise the packaging may be damaged and the material leaks. The transportation vehicle should be equipped with the corresponding variety and quantity of fire fighting equipment and leakage emergency treatment equipment. If there is an accident such as leakage on the way, you can respond in time. And the exhaust pipe of the vehicle transporting the goods must be equipped with a fire retardant device, and it is strictly forbidden to use wooden boats and cement ships for bulk transportation, so as to avoid the occurrence of fire and other dangerous conditions during transportation.

The safety risks during the use of 4-ether-3- (triether methyl) naproxen sodium solution are mainly in the following categories:
First, it is related to toxic reactions. If this agent accidentally enters the human body, it may cause many toxic symptoms. For example, it causes damage to internal organs, especially the liver and kidneys. The liver is responsible for detoxification, and the kidneys are responsible for excretion. Once the ingredients of the drug interfere with its normal function, or cause abnormal liver and kidney function, it can be life-threatening in severe cases. And if it comes into contact with sensitive parts such as the eyes, it will cause strong irritation, resulting in redness, swelling, pain, and even damage to vision.
Second, there is a fire hazard. The solution may be flammable, and it is easy to be ignited in a high temperature environment or in the event of an open fire, which will cause a fire. In the storage and use site, if the fire prevention regulations are not followed, if there is a fire source nearby or poor ventilation, a slight carelessness will cause a fire, and the spread of the fire will pose a huge threat to people and property.
Third, it involves environmental hazards. If the solution is not properly treated and flows into the environment, it will cause pollution to soil, water sources, etc. The microbial community in the soil may be unbalanced as a result, affecting plant growth; after the water source is polluted, not only will it harm aquatic life, but human drinking contaminated water will also damage health and destroy ecological balance.
Fourth, the operational risk cannot be ignored. During handling and use, if the container is not well sealed or the operator is negligent, causing the solution to leak, it will not only pollute the surrounding environment, but also may cause injury due to personnel contact. And if the operation is not in accordance with the standard procedures, if the protective equipment is not worn, it will also increase the risk of personnel exposure.
Therefore, in the entire use process of 4-ether-3- (triether methyl) naproxen sodium solution, the above safety risks must be highly regarded, and safety procedures must be strictly followed, and protective and emergency measures must be taken to ensure safety.
