1 + - + Hg - 5 + - + Arsenic - 2 + - + Pb - 4 + - + Methyl Hg - What are the main uses? These are all poisons, and their uses are various, and they are often harmful and cannot be ignored.
Mercury was often used in the past as a measuring device for measuring water, blood pressure, etc., because of its good flow performance and sensitivity. However, its toxicity is very high, and careless leakage can pollute the environment, endangering people's health, immunity and other systems.
Arsenic has been used in the production of water, and can be used to eliminate damage to protect crops. However, its retention will pollute soil and water sources. If people are exposed to or imported, it can cause skin diseases, cancer and other serious diseases.
It was used in storage ponds, printing, painting, etc. In storage ponds, water and its compounds were transformed and reversed in order to preserve and release energy. However, it can harm people's spirits, hematopoiesis, digestion and other systems, especially children's intelligence and education.
Methylmercury is mostly generated by the action of microorganisms in the environment on mercury. Its toxicity is low, and it is easy to be tired in organisms. It is enriched in food, and it is also harmful to human health. It can cause diseases such as normal and common loss.
Of course, these substances have their uses in the past, but due to their toxic hazards, some uses have been gradually restricted or eliminated to ensure human health and environmental safety.

What is the synthesis of 1-bromo-5-chloro-2-fluoro-4-methylbenzene?
To prepare 1-bromo-5-chloro-2-ene-4-methylbenzene, the following method can be followed.
First take an appropriate amount of benzene, and under specific reaction conditions, use a suitable halogenating agent, such as a brominating agent, to carry out the bromination reaction. This step requires attention to the temperature, time and proportion of the reactants in the reaction, so that the bromine atom precisely replaces the hydrogen atom at a specific position on the benzene ring to form a bromine-containing benzene derivative.
Next, under the action of a suitable catalyst, chlorine atoms are introduced. In this process, the choice of catalyst is crucial, and different catalysts or chlorogenic atoms are substituted in different positions on the benzene ring. After this reaction, a benzene series compound containing both bromine and chlorine atoms can be obtained.
Then, with the help of suitable organic synthesis methods, a carbon-carbon double bond is constructed in the compound to achieve the formation of alkenyl groups. This step may require the use of a specific elimination reaction, through careful regulation of the reaction conditions, to promote the removal of specific small molecules in the molecule, thereby generating a carbon-carbon double bond.
Finally, methyl is introduced through an alkylation reaction. Select the appropriate methylation reagent, in a suitable reaction environment, let the methyl group react with the previously obtained compound, and finally form the target product 1-bromo-5-chloro-2-ene-4-methylbenzene. During the whole synthesis process, each step of the reaction needs to be carefully controlled to ensure the high efficiency of the reaction and the high purity of the product. And the connection between each step cannot be ignored. According to the specific reaction characteristics, the separation and purification of the intermediate product should be properly carried out to achieve the final synthesis goal.

What are the precautions for storing and transporting 1-bromo-5-chloro-2-fluoro-4-methylbenzene?
In the storage and transportation of mercury, pentane, alkane, ethanol, toluene and other substances, there are many points to be paid attention to.
Mercury is a liquid metal, which is volatile and toxic. When storing, it should be placed in a closed container to prevent mercury vapor from escaping, polluting the environment and endangering the human body. The container material should be selected as one that is not easy to react with mercury, and should be placed in a cool and ventilated place to avoid increased mercury volatilization due to heat. When transporting, make sure that the container is stable and free of leakage, and should follow the relevant dangerous goods transportation regulations, equipped with necessary protective and emergency response equipment.
Pentane and alkanes are mostly flammable and explosive volatile liquids. When storing, the warehouse should be cool and well ventilated, away from fire and heat sources, and fireworks are strictly prohibited. The warehouse building should have fire and explosion-proof performance, and the electrical equipment must meet the explosion-proof standard. When storing, it should be separated from oxidants and strong acids to prevent dangerous reactions. When transporting, the vehicles and containers used must meet the requirements of fire prevention and explosion prevention, and there is a grounding device to eliminate static electricity. And the transporters should be professionally trained and familiar with emergency treatment methods.
Ethanol, although a commonly used chemical, is also flammable. Storage should be in a cool and ventilated warehouse, away from fire and heat sources, and the storage temperature should not exceed 30 ° C. It should be stored separately from oxidants, acids, alkali metals, etc., and should not be mixed with storage. When transporting, it is necessary to ensure that the container does not leak, collapse, fall or damage. In summer, it is best to transport it in the morning and evening to prevent sun exposure.
Toluene is a toxic and flammable liquid. Storage should be placed in a cool and ventilated warehouse, away from fire and heat sources. The temperature in the warehouse should not exceed 30 ° C. It should be stored separately from the oxidant. The lighting, ventilation and other facilities in the storage room should be explosion-proof. When transporting, it is necessary to follow the prescribed route and do not stop in residential areas and densely populated areas. Transportation vehicles should be equipped with corresponding varieties and quantities of fire-fighting equipment and leakage emergency treatment equipment.
