HCID 22885033,3-Bis(4-hydroxyphenyl)pentane

Procedure

3,3-Bis(p-hydroxyphenyl)pentane was prepared by repeating the procedure of Example I with the exceptions that 86 grams of 3-pentanone, and 0.5 gram of propanethiol were respectively employed in place of the cyclohexanone and butanethiol. The purity of the resulting above product was 99.5, and it had a melting point of 207° to 208° C. NMR data for this product was as follows:
