## Abstract Phenanthrene was treated with formaldehyde in the presence of sulphuric acid and the yields of resin obtained were dependent on the acid concentration and on the molar ration of formaldehyde to phenanthrene. All of the resins were composed of dimers, trimers, tetramers and higher oligom

## Abstract Phenanthrene‐formaldehyde resins of different oxygen content were reacted with phenol 110°C in the presence of a strong acid catalyst. Cleavage occurred at the dimethylene ether and acetal bridges joining the aromatic nuclei with the concomitant formation of phenanthrene‐formaldehyde‐ph
A procedure is described for radiolabeling proteins in vitro by reductive alkylation. The proteins are treated with [W]formaldehyde in the presence of sodium cyanoborohydride, a reducing agent that is stable in aqueous solution at pH 7. The advantage of this procedure is that the reaction can be car
