HCID 168587Formaldehyde--4-(2,4,4-trimethylpentan-2-yl)phenol (1/1)

Procedure

206 g (1 mole) of p-tert-octylphenol, 68.9 g (0.85 mole) of 37% formalin and 2.06 g of p-toluenesulfonic acid were condensed under water reflux for 3 hours. The reaction mixture was then dehydrated by heating to complete the reaction. There was obtained a p-tert-octylphenol/formaldehyde condensate having a softening point of 101° C.
