What are the physical properties of 4-chlorobenzenesulfonyl fluoride?
4 - The alkyl mercury shows the material characteristics of blue flame, and its quality has all kinds of strange things. This alkyl mercury, under normal circumstances, is mostly in the shape of a liquid, and the color is pure and clear, as if the water is condensed in the sky, clear but not miscellaneous. It is like glass, and there is a hint of brilliance when it flows. Touch it, feel its texture is smooth, like grease, but there is no greasy state, but there is a sense of coolness spreading from the fingertips.
Its density is greater than that of ordinary liquids. If it is filled in a vessel and placed on the case, it can feel its heavy state, showing its heavy quality. And its fluidity is quite good, shaking in the vessel, like clouds and flowing water, smooth and unstagnant.
When alkyl mercury comes into contact with fire, it appears like a blue flame. This blue flame is extraordinary, with a deep blue color, like the water of an abyss pool, and like the sky of the dark night, mysterious and alluring. The temperature of the flame is quite high, and the surrounding objects melt immediately at the touch. Its heat is strong, which can distort the air nearby, and it looks like a mirage.
Furthermore, the volatility of alkyl mercury is also unique. Although it is a liquid, in the air, it evaporates at a moderate rate, neither dissipating in an instant nor accumulating for a long time. The air it emits has a slightly peculiar fragrance, which is not a rich fragrance, but is clear and elegant. It seems to be absent, but it has been sniffing for too long, but I feel in a trance, so it can be seen that its qi also has a subtle effect.
In addition, the reaction between alkyl mercury and various substances is also very interesting. When encountering precious metals such as gold and silver, it can be fused with it, just like water milk, forming a strange alloy, which is tough and has a different luster. When encountering acids, the reaction is peaceful, and there is no violent state. However, under careful inspection, there are also subtle changes, or slight changes in color or shape. The material properties of alkyl mercury are very wonderful and fascinating to explore.

What are the chemical properties of 4-chlorobenzenesulfonyl fluoride?
Borax is an important compound of boron. It has been known to the world since ancient times. Its chemical properties are unique and quite wonderful.
The chemical name of borax is sodium tetraborate decahydrate, and the chemical formula is $Na_2B_4O_7 · 10H_2O $. Its appearance is often colorless translucent crystal or white crystalline powder. Borax can be hydrolyzed in water and is alkaline. This hydrolysis reaction is due to the combination of borate ions in borax and hydrogen ions ionized by water, which promotes the ionization equilibrium of water to move forward, which in turn increases the concentration of hydroxide ions in the solution.
Borax has certain reductive properties. Under certain conditions, the valence of boron in borax can change and participate in the redox reaction. For example, when interacting with strong oxidizing agents, borax can be oxidized, and the valence of boron element increases.
Borax reacts with acid to form boric acid. This reaction is a metathesis reaction, and its essence is to produce weak acid from strong acid. Boric acid is less acidic and relatively stable. The resulting boric acid can be dehydrated under specific conditions to form different forms of boron oxides.
Borax also has certain coordination ability. The outer electronic structure of boron atoms makes it easy to form coordination bonds with atoms with lone pairs of electrons. This property makes borax play an important role in the preparation of some complexes and the catalysis of some chemical reactions. The chemical properties of
Borax make it widely used in many fields. In ancient times, although people could not analyze its chemical properties from the microstructure as well as today, they also knew the wonderful use of borax in metallurgy and medicine by practical experience. With the development of science, the understanding of the chemical properties of borax is more in-depth, and its application field is also expanding.

What are the synthesis methods of 4-chlorobenzenesulfonyl fluoride?
To prepare ethyl 4-bromobenzoate, there are three methods.
First, ethyl benzoate is used as the beginning, and it is obtained by bromination. First, take an appropriate amount of ethyl benzoate, place it in the reaction kettle, use carbon tetrachloride as the solvent, add an appropriate amount of bromine, and add a small amount of iron powder or iron tribromide as the catalyst. At a suitable temperature, stir the reaction. This reaction mechanism is that under the action of bromine in the catalyst, an active bromine cation is generated, which attacks the benzene ring of ethyl benzoate and undergoes an electrophilic substitution reaction. Bromine atoms are introduced into the counterposition of the benzene ring, and then ethyl 4-bromobenzoate is obtained. The advantage of this method is that the raw materials are relatively easy to obtain and the reaction steps are relatively simple; however, the reaction selectivity may be difficult to precisely control, or ortho-bromination by-products may be formed.
Second, p-bromobenzoic acid and ethanol are used as raw materials and prepared by esterification reaction. The p-bromobenzoic acid and ethanol are placed in a reaction vessel in a certain proportion, an appropriate amount of concentrated sulfuric acid is added as a catalyst, and a small amount of zeolite is added to prevent burst boiling. Heat the reaction system to reflux, and use a water separator to remove the water generated by the reaction in time to promote the esterification reaction to proceed forward. This reaction is based on the principle of dehydration of acids and alcohols to form esters under the action of catalysts. The advantage is that the purity of the product is higher, because the raw material p-bromobenzoic acid has determined the substitution position of bromine; however, there are also deficiencies, the price of p-bromobenzoic acid may be higher, and the concentrated sulfuric acid is highly corrosive, and the post-treatment is slightly cumbersome.
Third, p-bromotoluene is used as the starting material. First, p-bromotoluene is oxidized to p-bromobenzoic acid, and a strong oxidant such as potassium permanganate can be selected. Under alkaline conditions, the reaction is heated to oxidize the methyl group to a carboxyl group. Then it is esterified with ethanol. The method is the same as the previous method, catalyzed by concentrated sulfuric acid, heated to reflux and remove water, and finally 4-bromo The advantage of this approach is that the cost of the raw material p-bromotoluene may be lower, but the drawback is that the oxidation step requires careful operation. Due to the use of strong oxidants, the reaction conditions are more severe, and various side reactions may occur during the oxidation process, which affects the yield and purity.
