What is the production process of Ligninsulfonic Acid?

Ligninsulfonic acid (Ligninsulfonic Acid) is the product obtained by sulfonation of lignin. The method is also often started by cooking wood chips with sulfuric acid. The wood chips are put into the digester, and the solution of sulfuric acid is combined. This solution contains more sulfuric acid, such as sulfuric acid and sulfuric acid. In high-grade environments, the sulfuric acid ($SO_3 ^ {2 -} $) is the phase of lignin. Lignin is a component of the cell wall of plants, which is rich, aromatic and multi-functional. Sulfate and some groups in lignin are reversed, and sulfuric acid groups ($- SO_3H $) are introduced into lignin. This sulfonation process greatly changes the solubility of lignin and dissolves in water to form lignin sulfonic acid. After cooking, it is used to remove untreated solids, such as lignin. The liquid contains lignin sulfonic acid and other soluble lignans. And apply the method of reducing its moisture and improving its degree. Or use a mixture of lignin to reduce it, remove it, and improve its degree. In this way, the available lignin sulfonic acid products can be used in multiple fields, such as dispersion and bonding.

What factors affect the market price of Ligninsulfonic Acid?

The market price of lignin sulfonic acid (Lignin sulfonic acid) is influenced by various factors. The first to bear the brunt is the source of raw materials. Lignin sulfonic acid is mostly extracted from pulping waste liquids such as wood and reed. If the output of such raw materials decreases sharply, or the supply is unstable due to natural disasters or policies, the price will fluctuate. If the mountain forest is damaged, the supply of wood is in short supply, the cost will rise, and the market price will also rise. Furthermore, the process is good. The process of extracting and refining lignin sulfonic acid is different, and the efficient and advanced method can reduce the cost and improve the quality. If the process lags behind, the energy consumption is high, the yield is low, and the cost is high, the price will be high. The application of new technology can optimize the process, reduce costs and increase efficiency, and make the price close to the The state of market supply and demand is also the key. In many fields such as petrochemicals and building materials, lignin sulfonic acid is widely used. If the market demand is strong and the supply is insufficient, the price will rise; on the contrary, if the demand is low and the supply exceeds the demand, the price will decline. The impact of policies and regulations should not be underestimated. As environmental protection policies become stricter, the production of lignin sulfonic acid may require higher environmental protection inputs, and the cost will increase, and the price will increase accordingly. Policies to encourage circular economy and green chemical industry may promote enterprises to improve their processes and reduce costs and stabilize prices. The trend of competing products also affects their prices. If there is a substitute product with excellent performance and reasonable price in the market, lignin sulfonic acid will be used as a guaranteed share, or the price will be adjusted

What should be paid attention to in the storage and transportation of ligninsulfonic acid?

Lignin sulfonic acid (Lignin sulfonic acid) is an important product of the wood chemical industry and is widely used in many fields. However, its storage and transportation require careful attention to many matters. In terms of storage, the first priority is moisture protection. Lignin sulfonic acid is hygroscopic. If placed in a humid environment, it is easy to absorb moisture and cause agglomeration, which affects the quality and performance. Therefore, it should be stored in a dry and well-ventilated place, and the storage container must be tightly sealed to prevent moisture from invading. Next time, pay attention to the temperature. High temperature environment or chemical reaction of lignin sulfonic acid will cause its properties to change. Therefore, the storage temperature should be maintained in the normal temperature range to avoid exposure to high temperature heat sources. Furthermore, avoid contact with oxidants and other substances. Lignin sulfonic acid has a certain chemical activity, contact with oxidants or cause violent reactions, endangering storage safety. As for transportation, packaging is crucial. Appropriate packaging materials need to be used to ensure that the packaging is complete during transportation and does not leak. And the packaging should be marked with warning labels to allow transporters to clarify its characteristics and points of attention. During transportation, environmental conditions should also be controlled. Such as avoiding long-term exposure to bad weather, especially high humidity and high temperature climate. At the same time, the interior of the transportation vehicle should be kept clean and free of impurities that may react with lignin sulfonic acid. In conclusion, proper storage and safe transportation of lignin sulfonic acid are of great significance in ensuring its quality, ensuring the efficiency of use, and maintaining the safety of personnel and the environment. It is necessary to follow the corresponding norms and requirements and proceed with caution.
