Application

Diphenyl ether is widely used as a heat transfer agent and a dye carrier. It can be used alone or as a mixture with other materials. Because of its reactivity, It can also be used as a raw material or chemical intermediate to produce commercial products. Diphenyl ether is used in the production of:

1. Diphenyl ether is employed as a processing aid in the production of polyesters. It acts as a chemical intermediate in the production of surface active agents and high temperature lubricants, fire retardants like polybrominated diphenyl ethers (PBDEs) and fragrance for detergents.

2. Heat transfer media – like DOWTHERMTM fluids used for heating industrial processes

3. Alkylated diphenyl oxides – used to make surfactants, greases and lubricants

4. Halogenated diphenyl oxides – used in insecticides, wood preservatives, and flame retardants for appliance casings in consumer electronic products

5. High temperature solvents

6. Coatings

7. Textile dye labeling

8. Plastics – like ethylene-propylene-diene monomer (EPDM) rubber that is used for membrane roofing materials

9. Diphenyl ether plays a vital role in the Ferrario reaction to produce phenoxathiin, which finds application in polyamide and polyimide production. Involving similar reactions, diphenyl ether is a significant side product in the high-pressure hydrolysis of chlorobenzene in the production of phenol.

10. Diphenyl ether is found in alcoholic beverages. Diphenyl ether is present in muscat grapes, green tea, vanilla, lemon balm, buckwheat, potato chips and grilled beef. Diphenyl ether is a flavouring ingredient.

Storage 

Color Code—Green: General storage may be used.Prior to working with diphenyl oxide you should be trainedon its proper handling and storage. Before entering confinedspace where this chemical may be present, check to makesure that an explosive concentration does not exist. Store intightly closed containers in a cool, well-ventilated areaaway from oxidizers. Store in tightly closed containers in acool, well-ventilated area away from heat. Sources of ignition, such as smoking and open flames, are prohibitedwhere this chemical is used, handled, or stored in a mannerthat could create a potential fire or explosion hazard. Metalcontainers involving the transfer of 5 gallons or more ofthis chemical should be grounded and bonded. Drums mustbe equipped with self-closing valves, pressure vacuumbungs, and flame arresters. Use only nonsparking tools andequipment, especially when opening and closing containersof this chemical.
