Raw Material: Dichloromethane (Methylene Chloride) Dichloromethane, also known as DCM, methylene chloride, or methylene bichloride, is an organic compound commonly used as a solvent in various industrial applications. Chemical Properties: Chemical Formula: CHCl CAS Number: 75-09-2 Appearance: Colorless, transparent liquid Odor: Irritating ether-like odor with a sweet, chloroform-like scent Solubility: Dichloromethane is slightly soluble in water and fully soluble in ethanol and ether. It exhibits low polarity and is miscible with many organic solvents, making it versatile for various applications. Physical Properties: Under normal usage conditions, dichloromethane is a non-flammable, low-boiling solvent. It serves as an effective replacement for flammable solvents such as petroleum ether and ether, particularly in environments where safety is a concern. However, caution is advised when vapor concentrations become elevated, especially in high-temperature air.
Purified Terephthalic Acid (PTA) Purified Terephthalic Acid (PTA) is a key organic compound formed through the reaction of paraxylene (PX), a secondary petroleum product, with acetic acid. PTA is primarily used in the production of Polyethylene Terephthalate (PET), a widely utilized polyester. During polymerization, PTA is combined with other chemicals to produce PET, which appears as a white crystalline powder. Key Characteristics: Safety: PTA is considered to be non-toxic and is classified as flammable, with the potential to ignite in the presence of sufficient air. Applications: As a crucial organic raw material, PTA finds extensive use in various industries, including: Chemical Fiber Industry: Essential for producing synthetic fibers. Light Industry: Used in a variety of consumer products. Electronics Industry: Integral in the manufacturing of electronic components. Construction Industry: Utilized in various construction materials and applications.
