【Usage】 Stannous methanesulfonate where fluorine atoms are attached to carbon atoms in graphene layers, resulting in partial or complete fluorination of graphene, is an important new type of graphene derivative. It not only retains the unique two-dimensional structure of graphene, but also has some excellent properties different from graphene due to the introduction of fluorine atoms. As a new derivative of graphene, fluorinated graphene has excellent physical and chemical properties such as low surface energy, strong hydrophobicity, and wide bandgap. It also has high temperature resistance, corrosion resistance, friction resistance, chemical stability, and excellent lubricity. Therefore, it can be widely used in high-temperature coatings, anti-wear lubrication coatings, and corrosion-resistant coatings. In addition, the unique properties of fluorinated graphene make it have potential applications in fields such as nanoelectronic devices, optoelectronic devices, and thermoelectric devices.
【Introduction】
Tin methylsulfonate is an important chemical product mainly used in electroplating and other electronic industries. It is a colorless and transparent liquid with a special pungent rotten egg flavor. The chemical formula of tin methylsulfonate is (CH3SO3) 2Sn, with a molecular weight of 308.93. It has a strong chelating effect in the plating solution and functions as a surfactant, which can enhance the conductivity of the plating solution.
In the electroplating industry, tin methylsulfonate has developed rapidly due to its environmental friendliness and excellent electroplating performance. Compared with traditional phenol sulfonic acid tin plating solution, methyl sulfonic acid tin plating solution has a wider electroplating process operation window, better stability, lower tin paste amount, and can produce product quality comparable to PSA tin plating process. Methyl sulfonic acid in tin plating solution is a natural substance that is easily biodegradable and environmentally friendly.
The CAS number for tin methylsulfonate is 53408-94-9, and its content is usually 50%. Impurities such as iron, copper, lead, nickel, and zinc are controlled within a certain range. Its specific gravity is 1.53, insoluble in water, but easily soluble in organic solvents such as methanol and ethanol. Appropriate safety measures should be taken when handling and using tin methylsulfonate, such as wearing protective clothing, gloves, goggles or masks, avoiding inhalation of dust, immediately rinsing with plenty of water and seeking medical attention in case of accidental contact with eyes, and seeking medical attention immediately if feeling unwell.
The market demand for tin methylsulfonate is expanding with the growth of the electronics industry, and it is expected that by 2023, the demand scale of China's methylsulfonic acid industry will reach 713 million yuan. The production process of tin methylsulfonate is subject to certain three waste pollution, resulting in significant environmental pressure, low operating rates of enterprises, and fluctuating production volumes. The main production enterprises are distributed in Jiangxi, Jiangsu, Hubei, Inner Mongolia and other places.
In terms of industrial applications, tin methylsulfonate is mainly used in the electronic electroplating industry for the production of tinplate, and its coating has good corrosion resistance and uniformity. The development of a new tin methylsulfonate plating solution has improved plating efficiency and uniformity, while reducing the environmental impact of the plating process.
In summary, tin methylsulfonate has significant value due to its applications in electroplating and other electronic industries, and its environmental characteristics also meet the demand of modern industry for environmentally friendly chemicals. With the continuous advancement of technology and the growth of market demand, the development prospects of tin methylsulfonate are promising.
