Physicochemical Properties of Meta Phenylene Diamine - 4 - Sulphonic Acid Sodium Salt

Meta + Phenylene + Diamine - 4 - Sulphonic Acid Sodium Salt, Chinese name m-phenylenediamine - 4 - sulfonate, its physicochemical properties are as follows:
This substance is usually white to light gray crystalline powder. In terms of solubility, it is easily soluble in water, which makes it easy to disperse and dissolve in many aqueous systems, just like "fish swim in water". In terms of stability, it is quite stable under normal temperature and pressure. If there is no extreme change in the environment, its chemical structure and properties can be maintained for a long time.
When encountering a hot topic, it is like a sudden wave on the surface of a calm lake, which will decompose and release harmful gases such as sulfur oxide and nitrogen oxide. These gases are like "poisonous fog", which is not only pungent and unpleasant, but also harmful to the environment and human health.
Its melting point data is of great significance for identification and purification, like a precise scale, which can help experimenters determine the purity and characteristics of substances. However, the specific melting point value will vary depending on the purity difference.
Sodium m-phenylenediamine-4-sulfonate has a neutral or near-neutral pH. This property makes it a mild "messenger" in many reactions or application scenarios that require strict pH, and will not disturb the system balance due to excessive acid or alkali.
In terms of chemical reactivity, because its structure contains amino groups and sulfonic acid groups, it is like having two "chemical keys". It can not only react with acids and bases, but also participate in many organic synthesis reactions, such as amidation, sulfonation, etc., and has important uses in dyes, medicine and other industries.

Meta Phenylene Diamine - 4 - Sulphonic Acid Sodium Salt

When making Meta+Phenylene+Diamine+-+4+-+Sulphonic+Acid+Sodium+Salt (m-phenylenediamine-4-sulfonic acid, sodium salt), many things need to be paid attention to.
First, the selection and treatment of raw materials are extremely critical. The quality of m-phenylenediamine and sulfonic acid raw materials must be high, and there must be few impurities, otherwise it will affect the purity and performance of the product. Before use, the raw materials should be carefully inspected to see if they meet the standards. If necessary, purification treatment should be carried out.
Second, the control of reaction conditions cannot be neglected. The temperature, the length of reaction time, and the change of pH all have a great impact on the reaction process and product formation. Generally speaking, the temperature should be precisely controlled within a certain range. If it is too low, the reaction will be slow. If it is too high, it is easy to cause side reactions and reduce the yield of the product. The reaction time also depends on the specific reaction situation. By monitoring the reaction process, the best reaction time node is determined. In terms of pH, it is necessary to choose an appropriate acid-base regulator according to the reaction mechanism to maintain a suitable reaction environment.
Third, safe production is the top priority. The production process may come into contact with harmful chemicals, and safety protection measures must be strengthened. Operators need to strictly wear protective equipment, such as protective clothing, gloves, goggles, etc., to prevent chemical substances from causing harm to the body. At the same time, the production site should be well ventilated and equipped with complete emergency treatment facilities, so that in case of emergencies, they can respond quickly and effectively.
Fourth, the separation and purification of the product cannot be ignored. After the reaction, an appropriate method should be selected to separate the product to remove unreacted raw materials, by-products and impurities. Common methods include filtration, crystallization, extraction, etc., which should be reasonably selected according to the characteristics of the product and the properties of impurities. The purified product also needs to be strictly tested to ensure that various indicators meet standards.

Meta Phenylene Diamine - 4 - Sulphonic Acid Sodium Salt

The market price range of Meta + Phenylene + Diamine - 4 - Sulphonic Acid Sodium Salt, that is, sodium m-phenylenediamine - 4 - sulfonate, often fluctuates due to a variety of factors.
Looking at the market in the past, the price of this compound is affected by the supply of raw materials, the difficulty of preparation process, and the amount of market demand. If the raw materials are abundant, the preparation method is simple, and the market demand is stable, the price may tend to be flat. On the contrary, if the raw materials are scarce, the preparation is complicated, and the demand surges, the price will rise.
Past records show that the price varies significantly from time to time. When the raw materials are abundant and the process is advanced, the price per kilogram may fall to tens of yuan. However, in case of shortage of raw materials, the process is blocked, and the price may rise to hundreds of yuan per kilogram.
Although it is difficult to determine the exact price range at present, according to past trends, if the market supply and demand are balanced and the preparation is stable, the price per kilogram may fluctuate up and down from 100 yuan. In case of market fluctuations, supply and demand imbalance, this range may change significantly. Generally speaking, its market price often fluctuates between tens of yuan and hundreds of yuan per kilogram, depending on the market situation at that time.

Meta Phenylene Diamine - 4 - Sulphonic Acid Sodium Salt Quality Standards

"Meta-phenylenediamine-4-sulfonic acid, sodium salt Common Quality Standards"
Meta-phenylenediamine-4-sulfonic acid, sodium salt, is an important raw material in the chemical industry, and its Quality Standards are related to the effectiveness of many industrial applications. Common Quality Standards are as follows:
First weight content. The content of this substance is mostly accurately determined by high-performance liquid chromatography. The content of high-grade products often needs to reach more than 98%, and the first-grade product must not be less than 95%. High content ensures the purity of its chemical reaction. In the manufacture of dyes, pharmaceutical intermediates, etc., it can ensure key properties such as product color and efficacy. If the content is insufficient, or the reaction is not sufficient, the output of impurities will increase, which will affect the quality of subsequent products.
Secondary analysis of appearance. Under normal conditions, meta-phenylenediamine-4-sulfonic acid, sodium salt is white to slightly yellow crystalline powder. If the appearance color is abnormal, such as severe yellowing or obvious agglomeration, or suggesting that the product is contaminated by impurities or chemically changed during storage and production, its quality may have been damaged.
Furthermore, the moisture content. Usually determined by the Karl Fischer method. Excessive moisture will not only dilute the active ingredients, but also may cause deliquescence, affecting its fluidity and stability. In general, the moisture content should be controlled below 1% to maintain the good physical and chemical properties of the product, and to ensure the quality stability during storage and use.
In addition, the inspection of related substances is also indispensable. With the help of thin-layer chromatography or liquid chromatography, it is necessary to detect impurities such as isomers and by-products that may exist. The total amount of impurities needs to be strictly limited, because it may interfere with the main reaction and change the performance of the product. For example, some impurities or dyes cause problems such as color cast and color fastness to decrease during dyeing.
Particle size is also a key consideration. Determined by sieving method, the appropriate particle size distribution is conducive to its dispersion and dissolution in the solvent, and the reaction efficiency is improved. Different application scenarios have different requirements for particle size. For example, when used in specific fine chemical products, the particle size needs to be more uniform and fine to ensure the uniformity of the reaction.
