Reactivity of alkylphenols in butanol solutions of formaldehyde

Reactivity of alkylphenols in butanol solutions of formaldehyde. Kucherenko, G. K.; Siling, M. I.; Mokotkin, A. V. (GIPI LKP, Moscow, USSR). Lakokras. Mater. Ikh Primen., (5), 18-19 (Russian) 1986. CODEN: LAMAAD. ISSN: 0023-737X. DOCUMENT TYPE: Journal CA Section: 35 (Chemistry of Synthetic High Polymers) The reactivity of alkylphenols with HCHO [50-00-0] in BuOH solns. was studied by gas-liq. chromatog. and characterized by the conversion rate vs. reaction time dependence for PhOH and alkylphenols in the presence of NaOH as a catalyst. The reactivity decreased through the m-cresol [108-39-4], o-cresol [95-48-7], p-tert-butylphenol (I) [98-54-4], p-cresol [106-44-5], and PhOH series. The reactivity was detd. by the effect of alkyl substituent in the ortho- and para-portion in the phenol ring on the electron d. The highest reactivity of m-cresol was due to the pos. induction effect of the Me group which involves a smaller amt. of C-C bonds. The higher reactivity of I compared to p-cresol was related to the stronger electron-donor effect of the tert-Bu than that of the Me group.
