Product Description
Diethyl Phthalate (DEP), identified by CAS number 84-66-2, is the diethyl ester of phthalic acid, also known as ethyl phthalate. This colorless, transparent oily liquid is characterized by its miscibility with organic solvents such as ethanol, ethyl ether, acetone, and benzene, while being insoluble in water. In China, Diethyl Phthalate suppliers primarily utilize DEP as a plasticizer, solvent, lubricant, fixative, and foaming agent for nonferrous materials. Additionally, many manufacturers in China produce DEP in bulk through the reaction of ethyl alcohol with phthalic anhydride in their factories. With the molecular formula C12H14O4, DEP plays a crucial role in various industrial applications. Consequently, this makes it essential for manufacturers seeking reliable diethyl phthalate bulk suppliers to enhance their production processes.

Applications & Advantages of Diethyl Phthalate
Manufacturers widely use DEP as a plasticizer, solvent, lubricant, and fixative. Also they utilize it as a foaming agent for nonferrous or rare metal mine flotation and employ it as a gas chromatographic fixative, alcohol denaturant, and spray insecticide. Further more, DEP demonstrates good compatibility with cellulose acetate, cellulose acetate butyrate, polyvinyl acetate, and polystyrene, making it a versatile choice for various industrial applications. Additionally, it is commonly utilized as a plasticizer for cellulose resins in many factories.
Packaging, Storage, and Transport
DEP is conveniently packaged in iron drums, with a net weight of 230 kg per barrel. For optimal storage, it is essential to keep the drums in a cool, dry warehouse, ensuring they are away from fire and strong oxidants.Prevent violent impacts during transportation to ensure safety.
