## Abstract Pentachlorophenol−^14^C~6~ was synthesized by chlorinating phenol−^14^C~6~ using aluminum chloride as a catalyst. Purification of the labeled pentachlorophenol involved the precipitation of the labeled product from an aqueous alkali solution with hydrochloric acid and two sublimations.

Abstract
2, 6‐Di‐tert‐butyl‐p‐cresol‐^14^C~6~ was synthesised by reacoting p‐cresol‐^14^C~6~ with isobutylene using concetentrated sulfurica acid as catalyst.
Purification of the Labelled butylated p‐cresol involved very careful recrystalliation of this product from absolute alcohol.
Proof of radiochemical purity was determined using thin layer chromatography and autoradiography. Internal liquid acintillation counting techniques were used to determine the apeacific activity of the compound.
