Abstract
1,216,013. 2,6-Dimethylphenol. BADISCHE ANILIN- & SODA-FABRIK A.G. 9 May, 1968 [10 May, 1967], No. 21942/68. Heading C2C. 2,6-Dimethylphenol is prepared by debutylating 2,6 - dimethyl - 4 - t. - butylphenol at 120- 250‹ C. in the presence of aluminium oxide, zirconium oxide and (or) an aluminium silicate as a catalyst, with or without alkali or alkalineearth metal compounds. The reaction may be effected at atmospheric or subatmospheric pressure. In one example, 4-t.-butylphenol is treated with aqueous formaldehyde and caustic soda to yield 2,6-bis-(hydroxymethyl)-4-t.- butylphenol, which is then hydrogenated in the presence of a copper chromite catalyst to yield 2,6 - dimethyl - 4 - t. - butylphenol; the latter is then debutylated as described above.
