Title: A process for producing valuable derivatives from phenols
IPC: C07C37/14
Filed: 1932-03-07
Abstract: Alkylphenols useful as antiseptics and germicides are prepared by the interaction of an unsulphonated phenol with an aliphatic or cyclic olefine, other than ethylene, at a temperature below 70 DEG  C. in the presence of concentrated sulphuric acid (i.e. not less than 90 per cent strength), preferably in an amount equimolal to the olefine employed.  The product, which is always a secondary or tertiary alkyl phenol, may be isolated, in admixture with the arylalkyl ethers also formed, by diluting with water and separating the upper layer, but in some cases an intermediate hydrolysis step is necessary, which is effected by refluxing with water or by distillation with superheated steam.  The phenol may comprise a monohydric or polyhydric aromatic compound, e.g. phenol itself, the cresols, resorcinol or naphthol. According to the examples, (1) 1000 cc. of commercial cresol is mixed with 1120 cc. of hexene-2 and 670 cc. of 95 per cent sulphuric acid and stirred with water cooling; on addition of water, the product separated into two layers, of which the upper is refluxed with water; the upper layer formed on settling is then distilled to give a mixture of hexylcresyl ethers and sec-hexylcresols which is separated by treatment with alkali; (2) resorcinol is treated with hexene-2 in the presence of 95 per cent sulphuric acid under the same conditions as in (1) but with the addition of carbon tetrachloride to facilitate the stirring; the product comprises sec-hexylresorcinols.  Reference is also made to the preparation of sec-amylphenol from phenol and pentene-2, sec-hexylphenol from phenol and hexene-2, sec-hexylcresol from cresol and hexene-2, sec-heptylphenol from phenol and sec-heptenes, tert-amylcresol from cresol and trimethylethylene, diisopropylphenol from phenol and propylene (2 mols.), and sec-hexylresorcinol from resorcinol and hexene-2.  Cyclohexene is also mentioned as a reactant. Specifications 214,866, 298,600, and 325,856, [all in Class 2 (iii), Dyes &c.], are referred to.
