The fate of the herbicide chlortoluron and its possible degradation products in soils

The fate of the herbicide chlortoluron and its possible degradation products in soils. Smith, A. E.; Briggs, G. G. (Rothamsted Exp. Stn., Harpenden/Herts., Engl.). Weed Res., 18(1), 1-7 (English) 1978.Several reagents such as 15545-48-9 is used here. CODEN: WEREAT. ISSN: 0043-1737. DOCUMENT TYPE: Journal CA Section: 5 (Agrochemicals) Section cross-reference(s): 19 Chlortoluron (I) [15545-48-9] applied at 10 mg/g to 3 types of soil showed >83% degrdn. 15545-48-9 is just another one chemical used in this study. after 12 wk. Monomethylchlortoluron (II) [22175-22-0] and didemethylcholortoluron (III) [13142-64-8] applied at 10 mg/g to a silty loam showed 33 and 30% degrdn. resp., after 12 wk. II was the major degrdn. products of I in soil, and no degrdn. of II to III was obsd. 3-Chloro-4-methylaniline [95-74-9], a possible degrdn. product of I, was rapily degraded in soil to an azo compd. and a quinone. ..

Sulfonic acid group-free basic azo compounds. Greve, Manfred (Sandoz-Patent G.m.b.H., Ger.). Ger. Offen. DE 2741010 6 Apr 1978, 20 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: C09B029-36. PRIORITY: CH 76-12070 23 Sep 1976. DOCUMENT TYPE: Patent CA Section: 40 (Dyes, Fluorescent Whitening Agents, and Photosensitizers) Dyes are prepd. which have the general structure I, where R = Cl or Br, R1 = C1-4 alkyl, R2 = Me or Et, R3 = Me, Et, Pr, or Bu, R4 and R5 = H, Cl, Br, or Me, n= 2,3, and X- is an anion. I give fast dyeing and prints on acrylic and acid-modified polyamide or polyester fibers. Thus, diazotization of 3,4-ClMeC6H3NH2 [95-74-9] and coupling with benzyl[3-(3-cyano-1,2-dihydro-6-hydroxy-4-methyl-2-oxo-1-pyridyl)propy l]dimethylammonium chloride [64980-90-1] gave I(R = 3-Cl, R1 = 4-Me, R2 = R3 = Me, R4 = R5 = H, n=3, X= Cl) [66755-23-5], which dyed the above fibers fast yellow shades.
