The chemical structure of (1-methylethyl) -benzenesulfonic acid, a sodium salt, is as follows:
This compound is composed of three parts. The first is the benzene ring. The benzene ring is a six-membered carbon ring. Each carbon atom is connected by a special conjugated double bond. It has high stability and unique chemical properties. It is often used as a core skeleton in organic chemical structures.
The second is (1-methylethyl), also known as isopropyl, which is connected to the benzene ring through a carbon-carbon single bond. The isopropyl group is composed of three carbon atoms, one of which is connected to the benzene ring, and the other two methyl groups are connected to the central carbon atom, giving the molecule a certain steric hindrance and specific physical and chemical properties.
Finally, the sulfonic acid group (-SO-H) and its sodium salt form. The basic body of sulfonic acid is a strong acidic group with good water solubility and ionization ability. It is connected to the benzene ring, so that the whole molecule has a certain hydrophilicity.

(1-Methylethyl) -Benzenesulphonicacid, Sodiumsalt What should I pay attention to when storing?
(1-Methyl ethyl) benzenesulfonic acid, that is, propyl benzenesulfonic acid, is required to pay attention to all kinds of things in order to ensure its stability and quality.
First, it is suitable for the existence of dryness. If this compound encounters moisture, it is easy to absorb, or cause its physical shape to be changed, such as the impact of moisture, or even the reaction of induction, which affects its performance. Therefore, it should be placed in the situation of dryness, and the package needs to be sealed to prevent moisture from invading.
Second, avoid high temperatures and open flames. Propylbenzenesulfonic acid is not a highly flammable material, but it is highly combustible in the environment or decomposition, etc., breaking its degradation. The open flame is more likely to be an uncontrollable danger, so it should be stored as a source of ignition, addition, etc., and the temperature should be kept at a constant or slightly lower temperature, generally not exceeding 30 ° C.
Third, it is not allowed to oxidize, oxidize, etc. Because of its specific chemical activity, it is oxidized and co-oxidized, or there is an oxidation reaction. The original connection may also lead to the original reaction, which will cause the change of its properties, and the normal function of the method. Store separately according to the chemical properties, and avoid mixing.
Fourth, properly store. On the storage container, clearly indicate the name, grid, storage date, etc. This is convenient for management and use, and in the event of an accident, others can also use this to quickly understand the characteristics of the product and take appropriate measures.
Therefore, be careful to wait for the storage of (1-methyl ethyl) benzenesulfonic acid. Pay attention to the above end, in order to ensure that it is determined in the shelf life of the product and lay a good foundation for daily use.
What are the physical properties of (1-Methylethyl) -Benzenesulphonicacid, Sodiumsalt?
(1-Methylethyl) -benzenesulfonic acid, sodium salt, that is, sodium isopropylbenzenesulfonate, is a common organic compound. Its physical properties are as follows:
Viewed at room temperature, it is mostly white to light yellow crystalline powder, which is easy to store and transport, and is also easy to disperse in many reaction systems.
Smell, this substance usually has no special odor. This property makes it suitable for use in many areas sensitive to odor, such as some cleaning products, without introducing undesirable odors.
When it comes to solubility, sodium isopropylbenzenesulfonate is easily soluble in water, and can ionize sodium ions and corresponding sulfonate ions in water to form a uniform and stable solution. This good water solubility makes it play a significant role in the chemical reaction of aqueous solution systems, detergent formulations, etc. Its dissolution process is relatively fast, and it can be miscible with water in any ratio, which provides convenience for its application in industrial and civil products.
The characteristics of its melting point and boiling point cannot be ignored. The specific melting point and boiling point values will vary due to factors such as purity. The relatively high boiling point ensures its stability under general conditions of use, and it is not easy to evaporate and lose easily due to temperature changes; the appropriate melting point makes it possible to control the temperature during a specific processing process to achieve its phase transformation to meet different process requirements.
In addition, the density of sodium isopropylbenzene sulfonate is also an important physical property. Although its density data will vary slightly due to accurate measurement conditions, it is generally maintained within a certain range. This density characteristic is of guiding significance for its metering, mixing and other operations during production, storage and use.
This physical property determines that sodium isopropylbenzene sulfonate is widely used in many fields, such as detergents, emulsifiers, printing and dyeing aids, etc.
What are the production methods of (1-Methylethyl) -Benzenesulphonicacid, Sodiumsalt?
(1-Methylethyl) -benzenesulfonic acid, sodium salt, that is, sodium isopropylbenzenesulfonate, the preparation method has been ancient, and is described in detail below.
Preparation of this agent in the past, one of the methods is to use cumene as the starting material. First, cumene is co-heated with sulfuric acid to undergo a sulfonation reaction. In this process, the sulfo group of sulfuric acid (SO 🥰 H) replaces the hydrogen atom on the cumene ring to form (1-methylethyl) -benzenesulfonic acid. This reaction requires careful temperature control. Due to high temperature, it is easy to cause side reactions to occur and generate too many impurities. After the sulfonation reaction is completed, the reaction solution is cooled, and then the sodium hydroxide solution is slowly added to make (1-methylethyl) -benzenesulfonic acid and sodium hydroxide neutralize, and then generate (1-methylethyl) -benzenesulfonate sodium salt, while water is generated. After the reaction is completed, the pure (1-methylethyl) -benzenesulfonate sodium product can be obtained by separation and purification methods, such as evaporation concentration, cooling and crystallization.
There is another method, using benzene and propylene as raw materials, under the action of a catalyst, an alkylation reaction occurs, and Mr. is formed into cumene. The catalysts used are often solid acids, such as molecular sieves, which can make the reaction conditions milder and improve the selectivity of the reaction. After obtaining cumene, the subsequent steps are the same as the above-mentioned method of starting with cumene, through sulfonation, neutralization, separation and purification, etc. The final product is (1-methethyl) -benzenesulfonate. This method is easy to obtain raw materials, and by optimizing the reaction conditions and catalysts, it can improve the yield and purity of the product, so it is quite commonly used in industrial production.
