Versuchsvorschrift

20 parts by weight of isobutene are passed into a mixture of 68 parts by weight of 2-methyl-3-phenylpropyl chloride and 3 parts by weight of hydrogen fluoride at 0° C. The mixture is then stirred for 12 hours at room temperature. The crude product is washed with water, dried over Na2CO3 and distilled. 36 parts by weight of 2-methyl-3-phenylpropyl chloride, boiling point 105° C./16 mm Hg and 32 parts by weight of 2-methyl-3-(p-tert.-butylphenyl)-propyl chloride, boiling point 80° C.-81° C./0.02 mm Hg, are obtained.
