1. Alum is a common chemical substance. It is used in many fields. In industry, it is often used as a water purification agent. Because alum can be hydrolyzed to form a colloid, this colloid has adsorption properties and can make impurities suspended in water accumulate, so it is used to purify water, make water clear, suitable for drinking or other uses.
2. Nitrate is also widely used. In the military field, nitrate is an important raw material for the manufacture of gunpowder. The preparation of gunpowder, nitrate is indispensable, it participates in the combustion reaction, provides oxygen, and makes gunpowder explode violently, playing a key role in war equipment such as artillery, muskets and other ammunition. In ancient times, the discovery and application of saltpeter greatly promoted the revolution of military technology. In the field of medicine, nitrate is also useful. Some nitrate substances can be used as medicine, with the effect of clearing away heat and purging fire, softening and dispersing knots, and can be used to treat some diseases. However, medication should be used with caution and follow the doctor's advice.
3. Aminobenzoic acid is very useful in the pharmaceutical industry. It is often used as a raw material for synthetic drugs and can participate in a variety of drug synthesis pathways. For example, it can be used to synthesize local anesthetics. By blocking nerve impulse conduction, it can make the local area lose pain, providing a painless environment during surgery or some medical procedures to facilitate treatment. In the cosmetic industry, aminobenzoic acid and its derivatives can be used as sunscreen ingredients. Because it can absorb ultraviolet rays, protect the skin from ultraviolet damage, reduce the risk of sunburn, tanning and skin cancer, and is an important part of many sunscreen products.

To prepare 1-ether, 2-ester, and 3-aminobenzoic acid, the method is as follows:
The method of preparing ether can make alcohols and sulfuric acid co-heat, or use halogenated hydrocarbons to react with sodium alcohol. Take the co-heating of alcohol and sulfuric acid as an example. Ethanol is dehydrated into ether between molecules under the catalysis of concentrated sulfuric acid and the condition of 140 ° C. This is a nucleophilic substitution reaction. The oxygen atom of the hydroxyl group of the alcohol acts as a nucleophilic agent to attack the carbon atom attached to the hydroxyl group of another alcohol molecule. Sulfuric acid acts as a catalyst to help the hydroxyl group convert into easy-to-leave water, thereby forming an ether bond.
The reaction of halogenated hydrocarbons with sodium alcohol to produce ethers. Taking bromoethane and sodium ethanol as an example, the bromine atom of bromoethane is attacked by the nucleophilic attack of ethoxy negative ions in sodium ethanol, and the bromine ions leave to obtain ethyl ether. This reaction condition is mild and the yield is quite high, which is a commonly used method for synthesizing ethers.
Ester production is often carried out by esterification of carboxylic acids and alcohols under acid catalysis. For example, acetic acid and ethanol are catalyzed by concentrated sulfuric acid and heated to form ethyl acetate and water. Concentrated sulfuric acid here not only acts as a catalyst, but also absorbs the water generated by the reaction, so that the equilibrium shifts to the right and increases In addition, it can also be reacted with alcohol by acyl halide or acid anhydride. This reaction rate is fast and does not require acid catalysis. For example, acetyl chloride reacts with ethanol to quickly generate ethyl acetate and hydrogen chloride. The operation is simple and the yield is very good.
Synthesis of aminobenzoic acid can be obtained by nitration and reduction of benzoic acid. Benzoic acid reacts with mixed acid (concentrated nitric acid and concentrated sulfuric acid mixture), and the nitro group replaces the hydrogen atom on the benzene ring to obtain nitrobenzoic acid. Because the carboxyl group is the meta-localization group, the nitro group mainly enters the meta-position. After that, the nitro group is reduced to an amino group with iron powder and hydrochloric acid or other reducing agents to obtain m-aminobenzoic acid. This synthetic route is easy to obtain raw materials and feasible to operate. It is a common
The above methods are common ways to synthesize 1-ether, 2-ester, and 3-aminobenzoic acid. In practical applications, the appropriate method should be selected according to the comprehensive consideration of raw materials, equipment, and costs.

It is appropriate to pay attention to such substances as methoxylbenzene, alcohol, and methoxylbenzene when they are stored in the environment.
If it is hidden, it should be placed in a well-connected place, and the source of fire and gas, to prevent their accumulation, and the risk of fire and explosion in case of open flames. And it should be kept tightly, so as not to cause the composition to be changed due to the lack of space. It should be well sealed and leak-proof, and it should also be kept in accordance with the regulations of the Department of Dangerous Products, to avoid bumps and collisions.
If it is related to human life, it is especially important to study the storage. Depending on its nature, it may need to be refrigerated, or it may need to be preserved. If it is damp or exposed to moisture, it is easy to lose its effectiveness, or even produce harmful things. Therefore, in the place where it is hidden, it is appropriate to control the temperature and temperature, and if there are any parts, it is necessary to prevent it from being damaged. Keep its packaging intact, and do not mix with other substances to avoid pollution.
Methoxybenzene has a certain degree of toxicity and flammability. The room used for storage and decoration is isolated from other objects, and the room has perfect fire protection, ventilation and leakage emergency management. If it is not used, it must be used in containers and equipment according to the method of endangering the quality of the product, and provide clear warnings. People should also be trained and aware of its danger and emergency disposal.
Well, these three are in the process of hiding, each because of its own nature, and there are things that need to be paid attention to. They must follow the rules to ensure safety.
