history

diphenyl ether(cas no.101-84-8) and many of its properties were first reported as early as 1901.

consensus reports

diphenyl ether and many of its properties were first reported as early as 1901.it is synthesized by a modification of the williamson ether synthesis, here the reaction of phenol and bromobenzene in the presence of base and a catalytic amount of copper:
phona + phbr → phoph + nabr
involving similar reactions, diphenyl ether is a significant side product in the high-pressure hydrolysis of chlorobenzene in the production of phenol

specification

the diphenyl ether with cas registry number of 101-84-8 is also known as benzene, phenoxy-. the iupac name is phenoxybenzene. it belongs to product categories of pharmaceutical intermediates; fine chemical & intermediates; organics; biphenyl & diphenyl ether. its einecs registry number is 202-981-2. in addition, the formula is c12h10o and the molecular weight is 170.21. this chemical is a clear pale yellowish liquid after melting and insoluble in water. it should be sealed in ventilated and dry place away from fire, heat, oxidants. what's more, it can be used as heat transfer medium and used for organic synthesis, manufacture of perfume and dyes.

physical properties about diphenyl ether are: (1)acd/logp: 4.21; (2)acd/logd (ph 5.5): 4.21; (3)acd/logd (ph 7.4): 4.21; (4)acd/bcf (ph 5.5): 932.39; (5)acd/bcf (ph 7.4): 932.39; (6)acd/koc (ph 5.5): 4647.71; (7)acd/koc (ph 7.4): 4647.71; (8)#h bond acceptors: 1; (9)#freely rotating bonds: 2; (10)index of refraction: 1.572; (11)molar refractivity: 52.69 cm3; (12)molar volume: 160 cm3; (13)surface tension: 38.4 dyne/cm; (14)density: 1.063 g/cm3; (15)flash point: 99.3 °c; (16)enthalpy of vaporization: 47.59 kj/mol; (17)boiling point: 258.3 °c at 760 mmhg; (18)vapour pressure: 0.0223 mmhg at 25 °c.

preparation of diphenyl ether: it is prepared by condensation reaction of chlorobenzene and phenol. the reaction needs catalyst copper and solvent caustic solution. when the reaction is complete, reactant is dealed with acid and the ether oil is vacuum distilled to obtain product.

(1) c6h5oh + naoh → c6h5ona + h2o
(2) c6h5ona + c6h5cl → c6h5oc6h5 + nacl

uses of diphenyl ether: it is used to produce 4-phenoxy-benzaldehyde by reaction with tris(diformylamino)methane. the reaction occurs with reagent alcl3 and solvent 1,2-dichloro-ethane at -13 - 1 °c for 16 hours. the yield is about 20%.

diphenyl ether is used to produce 4-phenoxy-benzaldehyde by reaction with tris(diformylamino)methane.
