In this material, phosgene is often active. The atom can be changed in the surrounding environment due to its high performance. In the field of synthesis, the phosgene group in this compound can be used as a reactive site. Or it can be replaced by a nucleus to introduce other functionalities, such as a spoon, so that the molecule can be delicately modified and synthesized into a more complex compound.
As for the "triethylmethyl" group, its molecular space is also deeply affected. This group has a certain position resistance effect, which can lead to the reverse direction in the reverse direction, making the reverse direction more attractive. In some catalytic reactions, it can affect the interaction of the substrate, like a shape of the hand, controlling the reverse process.
And "to its carboxyl group", the carboxyl group is a functional group, acidic. The carboxyl group of this compound is mainly used in esterification reactions. With the combination of alcohols, ester compounds can be formed under suitable conditions. Esters are widely used in many fields such as fragrances and solvents, such as floral fragrances. There is no shortage of this esterified compound, giving it a charming fragrance.
In addition, the carboxyl group can also be used to generate a carboxylic antidote. Under specific conditions, it breaks carbon-carbon to generate a compound with less than one carbon. This antidote is an important way to build a carbon skeleton in the synthesis. Moreover, all parts of this compound are identical to each other, and there are many uses that cannot be ignored in the synthesis, materials, and so on.

To make ethylene and remove triethyl sulfuric acid, the method is as follows:
First, the basis for ethylene preparation needs to be understood, and it is often obtained by dehydration of ethanol. Under the condition of concentrated sulfuric acid and heating, the intermolecular dehydration of ethanol produces ethylene.
To remove triethyl sulfuric acid, one method is water washing. Because triethyl sulfuric acid is soluble in water, the mixed gas generated by the water washing reaction can dissolve triethyl sulfuric acid into water and separate it from ethylene. However, after washing with water, the gas will contain more water vapor, and subsequent drying treatment is required.
Second, the alkali washing method can be used. Wash the mixed gas containing ethylene and triethyl sulfuric acid with sodium hydroxide solution. Triethyl sulfuric acid can react with sodium hydroxide to convert into water-soluble salts, which can be separated from ethylene. After alkali washing, the gas also needs to be dried to remove water vapor.
Distillation can also be used. Due to the low boiling point of ethylene, the boiling point of triethyl sulfuric acid is relatively high. Control the appropriate temperature so that the ethylene is first vaporized and separated, leaving the triethyl sulfuric acid in the distillation kettle for the purpose of separation. However, the distillation operation needs to pay attention to precise temperature control to avoid other impurities or side reactions in the ethylene.
To make ethylene and except for triethyl sulfuric acid, according to the actual situation, water washing, alkali washing or distillation can be selected to achieve the purpose of purifying ethylene.

First of all, mercury is a highly toxic substance, volatile, and its vapor enters the body, which can cause various diseases of the viscera, especially the liver, kidney and nervous system. Therefore, when storing mercury, it must be tightly sealed, placed in a cool and well-ventilated place, and away from fire and heat sources to prevent its gasification and escape. During transportation, it is necessary to strictly follow the regulations for the transportation of hazardous chemicals and use special containers to ensure that there is no risk of leakage.
Second, tetraethyl (triethyl) may be chemically active and specific reactive. When storing, it should be avoided to coexist with oxidizing and reducing substances to avoid severe reactions. The environment should be dry to prevent it from being hydrolyzed by moisture. During transportation, it is also necessary to prevent bumps and collisions, causing damage to the container and causing leakage.
In addition, to its carboxylic acids, such compounds may be corrosive and irritating. Storage requires a corrosion-resistant container, and the label is clear, indicating its dangerous nature. The ambient temperature and humidity should be appropriate to prevent deterioration. During transportation, protective measures must be comprehensive, and the loading and unloading process should be careful to prevent harm to personnel and the environment.
In addition, no matter whether it is stored or transported, there should be a complete emergency plan. If there is a leak, know how to deal with it quickly to reduce harm. Personnel also need to be professionally trained to be familiar with the characteristics of various substances and safe operation methods. In this way, it is necessary to keep the storage and transportation safe.
