Its CAS number is 119389-05-8. This product is factory - supplied with a low price, which provides a cost - effective option for customers. The appearance of 4 - phenylethynylphthalic anhydride may vary depending on its purity and manufacturing process, usually presenting as a fine powder or crystalline solid. It has certain chemical stability under normal conditions, but it should be stored away from strong oxidants, reducing agents, and high - temperature environments. The molecular formula of 4 - phenylethynylphthalic anhydride is C16H8O3, and its molecular weight can be calculated based on the atomic weights of carbon, hydrogen, and oxygen. High - purity 4 - phenylethynylphthalic anhydride is crucial for its applications in high - performance fields.<\/p>\n<h2 id=\"product_usage\">Utiliza\u00e7\u00e3o do produto<\/h2>\n<p>4 - phenylethynylphthalic anhydride has a wide range of applications in many fields. In the field of high - performance polymers, it can be used as a key monomer for the synthesis of heat - resistant and high - strength polymers. These polymers are widely used in aerospace, automotive, and electronic industries, where materials need to withstand high temperatures and mechanical stress. In the aerospace industry, components made from polymers containing 4 - phenylethynylphthalic anhydride can be used in engine parts and structural components of aircraft, effectively reducing the weight of the aircraft while maintaining high strength and heat resistance. In the electronic industry, these polymers can be used as insulating materials for printed circuit boards, providing excellent thermal and electrical insulation properties.<\/p>\n<h2 id=\"product_application\">Como utilizar o produto<\/h2>\n<p>When using 4 - phenylethynylphthalic anhydride, strict safety procedures should be followed. First of all, it is necessary to wear appropriate personal protective equipment, such as chemical - resistant gloves, safety goggles, and a lab coat. During handling, avoid direct contact with the skin and inhalation of dust. When using it for polymer synthesis, accurate measurement is required according to the specific reaction formula. The reaction usually needs to be carried out in a well - ventilated fume hood, and the reaction temperature and time should be strictly controlled according to the experimental procedure. After the reaction, proper post - treatment is also necessary, such as purification and separation to obtain the desired product.<\/p>\n<h2 id=\"usage_cases\">Casos de utiliza\u00e7\u00e3o<\/h2>\n<p>Case 1: A well - known aerospace company used 4 - phenylethynylphthalic anhydride to synthesize a new type of high - performance polymer. They mixed 4 - phenylethynylphthalic anhydride with other monomers in a specific ratio under strict temperature and pressure conditions. After a series of complex chemical reactions, a polymer with high heat resistance and excellent mechanical properties was obtained. This polymer was then used to manufacture engine fan blades. Compared with traditional materials, the new fan blades reduced the weight by 20% while increasing the service life by 30%, significantly improving the performance of the aircraft engine.<\/p>\n<p>Case 2: An electronic manufacturing enterprise used 4 - phenylethynylphthalic anhydride - based polymers as the insulating layer of printed circuit boards. By precisely controlling the synthesis process, they obtained polymers with excellent electrical insulation and thermal conductivity. The printed circuit boards made with these polymers showed better heat dissipation performance and electrical stability, reducing the failure rate of electronic products and improving the overall quality and reliability of electronic devices.<\/p>\n<h2 id=\"contact_info\">Informa\u00e7\u00f5es de contacto<\/h2>\n<p>If you have any questions or needs regarding 4 - phenylethynylphthalic anhydride, please feel free to contact us.
