- Isomer specific syntheses of chlorinated catechols and guaiacols relevant to pulp bleaching
-
A variety of chlorinated catechols and guaiacols relevant to pulp bleaching were synthesized by employing fundamental differences in the acidities of phenolic hydroxyl groups in chlorinated catechols, and directive effects in guaiacols.

- Synthesis, X-ray structure determination, and formation of 3,4,5-trichloroquaiacol occuring in kraft pulp spent bleach liquors
-
3,4,5-Trichloroquaiacol, which is formed during bleaching of chemical pulp and shown to bioaccumulate in fish, has been synthesized.The structure of the compound has been determined by means of X-ray analysis.The values of the 13C nmr chemical shifts and melting point differ from those previously reported.A reaction mechanism is suggested for the formation of 3,4,5- and 4,5,6-trichloroguaiacol.
