To prepare 2-hydrocarbon-1,3-naphthalene dimethyl anhydride, the method is as follows:
First take naphthalene as the starting material. Naphthalene is one of aromatic hydrocarbons, with a conjugated system, active in nature, and can be used as the basis for the reaction. Naphthalene is used as the raw material, and an acyl group is introduced through an acylation reaction. The commonly used reagent for the acylation reaction is an acyl halide or an acid anhydride, with an appropriate catalyst, such as aluminum trichloride and other Lewis acids. This reaction can introduce an acyl group at a specific position on the naphthalene ring to form an intermediate product. The intermediate product formed by
needs to undergo a series of reactions to construct the structure of the target molecule. Or through During the oxidation process, choose a suitable oxidizing agent, such as potassium dichromate acidic solution, potassium permanganate, etc., to convert the specific group into a carboxylic group or an anhydride group. During the reaction, attention should be paid to the control of the reaction conditions, temperature, pH, and reaction time are all critical. If the temperature is too high, it may cause more side reactions and the product is impure; if the temperature is too low, the reaction rate will be slow and take a long time.
After the reaction is completed, the product may contain impurities, and it must go through the steps of separation and purification. The method of recrystallization can be adopted. According to the different solubility of the product and impurities in different solvents, a suitable solvent is selected, the mixture of the product and impurities is dissolved by heating, and then the temperature is lowered. The product crystallizes and precipitates Column chromatography can also be used to separate the product from impurities by the difference between the stationary phase and the mobile phase.
To prepare 2-hydrocarbon-1,3-naphthalene dimethanhydride, the desired product can be obtained through the selection of raw materials, acylation, oxidation, separation and purification steps, and fine regulation of each link.

2-% -1,3-phenyldimethanhydride, chemical substances are also used in their use, so pay more attention to things, and do not ignore them.
The first heavy case is its toxicity. 2-% -1,3-phenyldimethanhydride may be irritating, and the skin and mucous membranes may cause damage, or even appear to be sensitive.

Its reactivity. This anhydride is active and easy to react to other substances. In this way, it is necessary to avoid the combination of oxidizing, burning, and other substances, which may cause a strong reaction and cause a dangerous situation. In addition, it is better to use it when it is added or encountered with open flames, or there is a risk of burning or exploding, and the source of open flames and burning is prohibited.
Furthermore, the method of its storage. It is advisable to store it in a place where things are dry and dry, and it is difficult to communicate, and it should be directly exposed to the tide and light. The container is dense to prevent moisture absorption or the reaction of objects in the air, so that the product is not safe. Check its storage regularly, and if there is any problem, set it up quickly.
Use it again, measure it carefully, and operate it according to the correct method. Do not measure it to avoid waves and accidents. It is used for anti-pollution, anti-control components, such as temperature, temperature, ratio, etc., to ensure anti-corrosion benefits and obtain long-term results.
