The mixing ratio of 75/25 is obtained from the corresponding ratio of intensities of the particularly characteristics signals in the 400 MHz-1H-NMR spectrum (CDCl3). The position of the signals is: 3-methyl-2-buten-1-yl compound: olefinic H: 5.25 (d), CH3: 1.64 (s) and 1.77 (s), benzylic <CH—6.00 (t), benzylic CH2—; 3.52 ppm (s) 3-methyl-1-butyl compound: CH3: 0.90 (d), benzylic <CH—5.35 (m), benzylic —CH2—; 3.54 ppm (s).
