3,4-Diethylbenzene-1-sulfonate sodium, which is a commonly used compound in the chemical industry, its main uses are as follows:
1. ** Surfactant **: It has a unique molecular structure, one end is hydrophilic and the other end is lipophilic. In aqueous solution, it can significantly reduce the surface tension and promote the liquid to spread and penetrate more easily. For example, in detergents, it can effectively reduce the interfacial tension between water and oil stains, making oil stains more easily dispersed in water to achieve a cleaning effect; in textile printing and dyeing, the dye aid better infiltrates the fabric and makes the dyeing uniform.
2. ** Emulsifier **: It can form a stable emulsion between the oil phase and the water phase that are incompatible with each other. Taking pesticide emulsifiable concentrate as an example, it can evenly disperse oil-soluble pesticides in water, improve the stability and ease of use of pesticides, and help the agent to better adhere and spread on the surface of plants, and enhance the efficacy.
3. ** Industrial additives **: In the paper industry, it can be used as a deinking agent to help remove waste paper inks and realize fiber recycling; in the paint industry, it can improve the leveling and stability of coatings, prevent pigment sedimentation, and improve the quality of coatings.
4. ** Catalyst carrier **: Its special structure and properties can provide active check points for certain chemical reactions and promote the reaction. In organic synthesis reactions, specific catalysts can be supported to improve catalyst dispersion and activity, while facilitating catalyst recovery and reuse.

3,4-Diethylbenzene-1-sulfonic acid is a natural compound, and its physical properties are as follows:
The outer surface is mostly white to light-colored powder or solid crystal, which is easy to see. It has good water solubility and can disperse and dissolve uniformly in water. This property makes it easy to mix, dissolve, and be effective in polyaqueous systems.
The high melting phase, at a specific high temperature, only melts into a liquid. In terms of density, there is a certain phase density due to the formation of specific molecules. In processes involving mixing, separation, etc., the density factor is of paramount importance, which affects the distribution and behavior of the composition in different media.
In addition, it has absorbency, and it is easy to absorb moisture in the moisture environment. It is necessary to pay attention to moisture-proof measures when it is stored. It may not affect its own physical shape and even chemical properties due to moisture absorption, and dry its normal use efficiency.
In addition, the solubility, melting, density and absorbency of 3,4-diethylbenzene-1-sulfonic acid are in many fields such as chemical industry, materials, daily chemical industry, etc., all of which play a decisive role in their application, engineering and chemical properties, and deeply affect their biological performance.

3,4-Diethyl-1-pentenonitrile, this is an organic compound. Its chemical properties are as follows:
1. ** Addition reaction **: The carbon-carbon double bond is the check point for reactivity. It can be added with hydrogen under the action of a catalyst to produce 3,4-diethylpentenonitrile. The process is like a strong man absorbing energy and adding bricks. If nickel is used as a catalyst, under appropriate temperature and pressure, hydrogen and double bonds meet, and hydrogen atoms are skillfully added, and the double bonds become single bonds.
2. ** Oxidation reaction **: The carbon-carbon double bonds are vulnerable to attack by oxidants. In case of strong oxidants, such as acidic potassium permanganate solution, the double bond breaks, and various oxidation products are formed according to structural differences. This situation is similar to the fragile part being hit by external force, and the structure collapses and reorganizes. If the double-bonded carbon atom is connected to a hydrogen atom, or oxidized to a carboxyl group.
3. ** Substitution reaction **: A hydrogen atom on a carbon atom connected to a nitrile group can be replaced by other atoms or groups under certain conditions. For example, under the action of appropriate catalysts and reagents, a halogen atom can replace the hydrogen atom. This is a position interchange between atoms, like a chess piece rearrangement.
4. ** Hydrolysis reaction **: The nitrile group can be hydrolyzed under the catalysis of an acid or base. Under acidic conditions, carboxylic acids and ammonium salts are gradually hydrolyzed; under basic conditions, carboxylic salts and ammonia are formed. This process is like the metamorphosis of a compound, and under the guidance of acid and base, the structure changes to a new material form.

To prepare 3% 2,4-diallyl-1-naphthol ethyl ether, the method is as follows:
Prepare all required things first, such as 2,4-diallyl-naphthol, halogenated ether, alkali, solvent and the like. Halogenated ether can be a genus of bromoethyl ether and chlorinated ether. Potassium carbonate, sodium carbonate and the like are commonly used in alkali agents, and the solvent can be selected as N, N-dimethylformamide, acetonitrile, etc., depending on the situation.
Put 2,4-diallylnaphthol, halogenated ether and alkali in an appropriate proportion into a reaction kettle containing solvent. In proportion, the molar ratio of about 2,4-diallyl naphthol to halogenated ethyl ether is 1:1.2-1:1.5, and the amount of alkali is slightly more than 2,4-diallyl naphthol, about 1.1-1.3 moles.
Then, the temperature control is used to warm the reaction system in the kettle to a certain temperature. This temperature is usually between 60-80 degrees Celsius, which is fine-tuned due to different reactants and solvents. At this temperature, the reaction is allowed to continue for several hours. Generally speaking, the reaction time is about 4-6 hours, and it needs to be stirred evenly during this period to make the reaction sufficient.
After the reaction is completed, pour the reaction solution into an appropriate amount of water and extract the product with an organic solvent. The organic solvent can be selected from ethyl acetate, dichloromethane and the like. After extraction, the organic phase is collected, the water is removed with a desiccant such as anhydrous sodium sulfate, and the desiccant is filtered.
Then the filtrate is distilled under reduced pressure to remove its solvent to obtain a crude product. After the crude product is refined by column chromatography or recrystallization, a pure 3% 2,4-diallyl-1-naphthol ethyl ether can be obtained. For column chromatography, a suitable silica gel is selected as the stationary phase, and petroleum ether and ethyl acetate are prepared into a mobile phase in a certain proportion; for recrystallization, a suitable solvent, such as ethanol, acetone, etc., is selected, the crude product is dissolved by heating, the crystallization is cooled, and the crystals are filtered and dried.

3% sodium salt of 2C4-diethylbenzene-1-sulfonate is commonly used in chemical industry. During storage and transportation, many matters need to be paid attention to.
First words storage. This salt should be placed in a cool, dry and well-ventilated place. Because if it is in a humid place, it is prone to moisture and agglomeration, which affects its quality and use effect. And it should be kept away from fires and heat sources to prevent fires. Although this salt is not flammable, it should be stored separately from oxidants and acids to avoid mixed storage. Due to its chemical properties, it can be mixed with other substances or react chemically, causing danger.
As for transportation, there is also attention to it. The transportation vehicle must be dry and clean, and there are no other residues that may react with it. During transportation, it should be protected from exposure to the sun, rain and high temperature. During summer transportation, it is advisable to choose the morning and evening when it is cool to avoid the high temperature during the day. When loading and unloading, it should be lightly loaded and unloaded, and should not be operated brutally to avoid damage to the packaging. If the packaging is damaged, salt leakage will not only be wasted, but also cause pollution to the environment, and there are also potential safety hazards. Once it leaks, it should be cleaned up in time to avoid its spread. Transportation personnel also need to understand the characteristics of this material and emergency treatment methods. In case of emergencies, they can properly deal with it.
