The item is easily soluble in ethanol, ether, soluble in acetone, benzene, carbon tetrachloride, as well as virtually insoluble in water. Shop in a trendy, ventilated storehouse. Keep away from fire and heat resources. It should be stored individually from oxidants and acids, and also need to not be blended. Equipped with the suitable range as well as quantity of fire equipment. Storage locations should be furnished with emergency situation launch tools and also suitable containment products.
Diethyl phthalate can be utilized as plasticizer, solvent, lube, fixative, frother for colored or rare-earth element mine flotation protection, gas chromatography fixative, alcohol denaturant, spray insecticide. It can be utilized for plasticization of plastics and fiber resins. Its low temperature adaptability and also toughness are much better than dimethyl phthalate. It is usually used in cellulose acetate with dimethyl phthalate to boost the water resistance, Elasticity, light resistance as well as solidity; for nitrocellulose, products with high strength, great light resistance as well as no smell can be acquired. DEP can be utilized as a tackifier for polyvinyl acetate emulsions, as a solvent and also lubricating substance in pharmaceutical manufacturing, as a fragrance retainer, as a safe adhesive for food packaging films, as a starting product for flotation of tinted or rare-earth element mines. Foaming representative, gas chromatography fixative, alcohol denaturant, spray pesticide, stabilizer for rocket propellant, and so on. Although DEP has a certain constraint due to its high volatility, it is used in other areas, such as the manufacturing of acetic acid and In cellulose butyrate, there is still a really wide market.
Diethyl Phthalate Uses
Diethyl phthalate is a widely used organic chemical product. DEP can be used as a plasticizer for plastics and rubber products, which reduces the hardness of the product at low temperature and prolongs its service life. The joint addition of dimethyl diformate to the modified cellulose after acetic esterification can improve the hardness of the product, enhance its elasticity, and withstand the effects of strong light and water; the nitro group of diethyl phthalate is added Cellulose, strength and lightfastness are improved, eliminating product odors.
In addition, DEP can also be used as a solvent and lubricating oil for pharmaceuticals, retain the aroma of spices, act as a stationary liquid in gas chromatography, a foaming agent in the flotation process of metal mines, and a denaturant that makes alcohol exclusively for industry rather than food. Due to the low toxicity of DEP, it can be used as a plasticizer for non-toxic adhesives in food packaging materials. DEP is often used as an intermediate of rodenticides dimouse, ratan, and chlorpyrone, and can also be used as a solvent for cellulose and esters; because of its good compatibility with most resins such as nitrocellulose, cellulose acetate butyrate, and polystyrene Capacitive, often used as cellulose resin plasticizer, and can also be used in lubricants, gas chromatography fixatives, alcohol denaturants and spray insecticides, etc. For cosmetics such as nail polish, DEP is often added to reduce its brittleness and avoid chipping .

Preparation of Diethyl Phthalate
- Traditional synthetic methods
Phthalic anhydride and anhydrous ethanol are esterified under the action of concentrated sulfuric acid, and the esterified liquid is neutralized, dehydrated and fractionated to obtain the finished product. Sulfuric acid has the advantages of strong acidity, strong water absorption and low price, but it is also oxidizing, which may lead to side reactions such as sulfonation, carbonization or polymerization, resulting in poor selectivity, low reaction yield, and corrosion of equipment, resulting in a large amount of waste liquid, causing environmental pollution. - Solid acid as catalyst method
In a three-necked flask equipped with a thermometer, agitator and a reflux condenser, add a certain amount of phthalic anhydride and 10 mL of absolute ethanol, heat, when the acid anhydride solid is dissolved, add a certain amount of catalyst, and carry out stirring and refluxing. Esterification reaction for 1h, then stop stirring, install a water separator, add an appropriate amount of cyclohexane to reflux with water, until the dehydration is complete, steam out excess ethanol and cyclohexane, and stop heating when the temperature rises to 100 °C , and stand to cool to obtain a crude product. The cooled crude product was first filtered out of the catalyst, then the product adhered on the catalyst surface was washed with a small amount of ethyl acetate and incorporated into the reaction product, added 5% sodium carbonate solution and neutralized to pH=5～6, separated, The organic layer was washed with saturated saline solution gradually until neutral. The water layer was separated and discarded, and the organic layer was dried by adding anhydrous MgSO 4 , distilled, and the fraction at 295-298° C. was collected, which was diethyl phthalate.
