Abstract: THE communication of Gyenes, Rose and Sehon1 prompts us to record briefly some observations in a closely related field.

Formaldehyde condensations with phenol and its homologues. XII. The dehalogenation of halogenated diphenylmethanes having halogen substituents in the nucleus

Abstract: The preparation of I-hydroxy-2 : 6-bis-(2-hydroxybenzyl)benzene by dehalogenation of the corresponding trichloro compound was described in Part X of this series (Finn, Lewis & Megson, 1950). The removal of the chlorine was effected by treatment of the boiling amyl alcohol solution of the compound with sodium. The yield was poor and amounted to only 5% of theory. It has now been found that the dehalogenation can be achieved more satisfactorily by treatment of a solution of the diphenylmethane derivative in aqueous sodium hydroxide with Raney nickel-aluminium alloy. A yield of about 50% of theory is obtained. 2 : 2′-Dihydroxydiphenylmethane may be obtained from 2 : 2′-dihydroxy-5 : 5′-dichloro-diphenylmethane by the same means and the method has been used to prepare 2 : 2′-dihydroxy-3 : 5-dimethyldiphenylmethane, 2 : 2′-dihydroxy-3 : 3′ : 5 : 5′-tetramethyldiphenylmethane, and I-hydroxy-3 : 5-dimethyl-2 : 6-bis-(2-hydroxybenzyl)benzene.

Observations on the bactericidal action of hexyl resorcinol aerosols.

Abstract: The bactericidal action of hexyl resorcinol vapour on airborne clouds of a variety of micro-organisms including pathogens and a virus has been investigated. In addition to killing rates comparable with those found by previous investigators, a phenomenon, which we have called the initial kill, has been demonstrated and experiments carried out to explain its mechanism. Under certain circumstances it enhances the elimination of viable bacteria very substantially.We are indebted for technical assistance to Corporal J. C. G. Harris, R.A.F., to Messrs B. F. Courtnay and C. M. R. Pitman, and to members of the Virus Research and Field Trials Sections.
