Abstract
1,236,389. Diphenyl ethers. MIDLANDYORKSHIRE TAR DISTILLERS Ltd. 15 Nov., 1968 [22 Nov., 1967], No. 53181/67. Heading C2C. [Also in Division C5] A process for the production of a diphenyl ether that is unsubstituted in the 2-position in which each benzene nucleus is substituted by at least one secondary or tertiary alkyl group, preferably with up to eight carbon atoms, and in addition optionally bears one or more primary alkyl group substituents, comprises passing the appropriately substituted phenol in the vapour phase over a thoria catalyst at a temperature between 380‹ and 500‹ C. Examples disclose the preparation of 4,4<SP>1</SP>-ditertamyldiphenyl ether, stated to be novel, 4,4<SP>1</SP>-ditertbutyldiphenyl ether, 3,3<SP>1</SP>- and 4,4<SP>1</SP>-diisopropyldiphenyl ether, the latter of which may, if desired, be oxidized to 4,4<SP>1</SP>-dicarboxydiphenyl ether, e.g. by 40% nitric acid.
