《Phenolic and chlorophenolic oligomers in chlorinated pine kraft pulp and in bleach plant effluents》 was written by Erickson, M.; Dence, C. W.. Related Products of 37908-97-7 And the article was included in Svensk Papperstidning in 1976. The article conveys some information:
The estimated total concentration of phenolic substances in the undiluted oxidized spent chlorination liquor of softwood kraft pulp (kappa number 28.2) chlorinated with 6.0% Cl was ∼100 ppm but was ∼190 ppm in the oxidized caustic extraction liquor of pulp chlorinated with 3.6% Cl. Eleven phenolic derivatives were detected in the spent chlorination liquors of the 2 levels of Cl application using gas chromatog. and mass spectrometric anal. The combined yields of the phenolic oxidation products indicated a concentration of ∼10 ppm for phenolic residues in each of the original liquors. The permanganate oxidation products of the chlorinated pulps were the same as those found in the spent chlorination and caustic extraction liquors but in higher total concentration In the experimental materials used by the author, we found 3,5-Dichloro-4-methoxybenzoic acid(cas: 37908-97-7Related Products of 37908-97-7)
3,5-Dichloro-4-methoxybenzoic acid(cas: 37908-97-7) belongs to organochlorine compounds. Alkanes and aryl alkanes may be chlorinated under free radical conditions, with UV light.

Aryl chlorides may be prepared by the Friedel-Crafts halogenation, using chlorine and a Lewis acid catalyst.
