Formaldehyde condensations with phenol and its homologues. XIII.The relative reactivity of the ortho AND para Positions in the formation of alcohols of substituted phenols

Abstract: In earlier papers of this series it has been shown that the action of formaldehyde on 3 : 5-xylenol in the presence of sodium ethoxide catalyst results in the formation of an ortho-ortho-dialcohol. Attempts to prepare as ortho-monoalcohol by modification of the reaction conditions foiled. A consideration of the behaviour of other substituted phenols appears to lead to a generalization that when both meta positions and sometimes when the para position of phenols, relative to the phenolic hydroxyl group, are occupied by substituents, the introduction of a methylol group into one ortho position results in an enhanced reactivity of the other. Such an enhanced reactivity of one ortho position would explain why dialcohols are readily formed, but that the presumably intermediate mono-alcohol cannot be isolated. Attempts to prepare some trinuclear substituted compounds by condensation of di-ortho-substituted phenols with various intermediates failed. The explanation of this failure is probably due to a decreased reactivity of the para position in these di-ortho-substituted phenols.

An Effect of Hexylresorcinol on Bacterial Aerosols

Abstract: DURING the course of some investigations into the effects of volatile germicides on the viability of bacterial aerosols, we have encountered a phenomenon which appears to have escaped the notice of other workers in this field, and which not only accounts for contradictions in some existing experimental results, but also suggests that in certain circumstances substances such as hexylresorcinol may be of considerably greater value as barriers to cross-infections than has been supposed hitherto.
