What is the main use of the polymer sodium salt of naphthalenesulfonic acid and formaldehyde?
Arsenic is a compound of ethanol, and its main purpose is to use mercury.
Mercury is also an alloy of mercury and other gold. Arsenic, that is, arsenic trioxide, is highly toxic. Ethanol, on the other hand, is often soluble. Arsenic combines with ethanol to form mercury, and its uses are many in the fields of medicine, metallurgy, and chemistry.
In the past, mercury was used to treat skin diseases such as scabies. Mercury can be used to cure skin parasitic bacteria due to its special chemical properties. However, due to the toxicity of arsenic, it is rarely used today, but it was used in the past.
As for metallurgy, mercury can be used to extract gold and other metals. Because it can form mercury in metals, metals, etc., and other metals can be divided. The method of adding etc., so that the mercury is lost, leaving the gold and gold. This has been in place since ancient times, helping metallurgy to extract fine gold and jade.
In the chemical process, mercury is also an important factor. It can be used in some chemical reactions, as a catalyst or a specific chemical reaction, to change the rate and direction of the reaction, and to promote the next step in chemical research.
For example, mercury, the compound of arsenic and ethanol, has an important function in many fields. However, due to toxicity and other reasons, it has been used in the past, but it has left one of the important colors of the ink in the development of ancient science and technology.
What are the chemical properties of the polymer sodium salt of naphthalenesulfonic acid and formaldehyde?
The chemical properties of phenolic compounds of tannic acid and methanol are as follows:
Tannic acid is a polyphenolic carboxylic acid formed from polyphenol-based benzoic acid, which is acidic and can be reversed. Methanol and monohydric alcohol are typical of alcoholic groups, and can generate substitution, elimination and other reactions. The combination of the two forms phenolic formaldehyde, and its chemical properties are special.
Phenolic formaldehyde has high quality. Because of its molecular properties, which contain phenyl and methyl, the molecular force is increased, and higher energy is required to break it. Therefore, it can maintain the stability at high degrees, and is often used in the manufacture of resistant materials.
Its chemical properties are also good. Phenolic polymers are inert, and generally acids, polymers, and polymers are soluble in order to make them appear bright and reverse. Due to the high density and stability of benzene, methylenes also increase the molecular quality, so that they can remain stable in the polymers environment, and can be used in containers, pipelines, etc. that store or connect chemicals.
Phenolic has good performance. Because its molecules are free to migrate, and are dense, it can be widely used in the field, such as outside the generator and materials, etc., which can effectively prevent leakage and ensure the safety of use.
Phenolic surface properties are special and have certain hydrophobicity. The proportion of non-reactive groups such as benzene and methyl in its molecules is large, so that the surface energy of the material is low, the contact angle between water and water is large, and the water content is low, which can be used for moisture-proof and waterproof material surface treatment.
Phenolic can be hydrolyzed and reversed under certain conditions. It has good quality, but under acid or high temperature and high temperature, methyl may crack, hydrolyze, and break the phenolic. This property needs to be considered in some special applications or material recycling.

What is the preparation method of the polymer sodium salt of naphthalenesulfonic acid and formaldehyde?
To make the polymer of musk acid and methanol, that is, to make methyl acetate, the method is as follows:
Prepare the required utensils and medicines first. The utensils include flasks, condensers, liquid separation funnels, conical bottles, etc., all of which must be clean and dry. The medicines are musk acid (ie acetic acid) and methanol, both of which are chemically pure.
In the flask, according to an appropriate ratio, first inject an appropriate amount of methanol, and then slowly pour in musk acid. The molar ratio of musk acid to methanol is probably 1:1.2. A slight excess of methanol can promote the reaction to proceed in the direction of ester formation.
Add catalyst later. Concentrated sulfuric acid is often used as a catalyst because of its good catalytic effect. However, concentrated sulfuric acid is highly corrosive. When adding, it must be slowly and shaken while adding to prevent local overheating. The dosage is about 3% - 5% of the total volume of the reaction mixture.
Properly connect the flask to the condenser pipe. The condenser pipe is filled with water, the lower mouth is filled with water, and the upper mouth is filled with water to ensure the cooling effect. Slowly heat the flask with an alcohol lamp or an electric furnace to keep the reaction mixture in a slightly boiling state. During the reaction process, the liquid in the flask can be seen turning over, and the steam rises along the condenser pipe. After cooling, the droplets return to the flask. This reaction is a reversible reaction. Heating can speed up the reaction rate, and the generated methyl acetate is continuously evaporated and separated from the reaction system to facilitate the balance right shift.
After the reaction is completed, when the liquid in the flask is slightly cold, pour it into the separation funnel. Because the reaction product contains unreacted musk acid, methanol and catalyst sulfuric acid in addition to methyl acetate. Washing with saturated sodium carbonate solution first can neutralize the unreacted musk acid, dissolve methanol, and reduce the solubility of methyl acetate, which is conducive to stratification. Shake the separation funnel to see that the liquid is stratified. The upper layer is an organic phase such as methyl acetate, and the lower layer is an aqueous phase.
Separate the upper organic phase, and then wash it with saturated salt water to remove the residual sodium carbonate. Then dry it with anhydrous magnesium sulfate or anhydrous calcium chloride and let it stand for a period of time to remove the residual moisture in the organic phase.
Finally, the dried organic phase is transferred to a distillation flask for distillation. Collect the fraction in a specific temperature range, which is methyl acetate. The boiling point of methyl acetate is about 57 ° C - 58 ° C. Collect the fraction at this temperature range to obtain pure methyl acetate, which is a polymer of musk acid and methanol.
