اثر اسید کلروسولفوریک بر روی نیتریلهای عطری سنتز S-Triazine و Dibenzamide های جدید

(S)-2,2′-Dihy­droxy-N,N′-(6-hy­droxy­hexane-1,5-di­yl)dibenzamide

In the title compound, C(20)H(24)N(2)O(5), the dihedral angle between the two roughly planar salicyl-amide fragments [r.m.s. deviations = 0.043 (2) and 0.149 (2) Å] is 25.50 (5)°. The mol-ecular conformation is stabilized by intra-molecular O-H⋯O hydrogen bonds involving phenol -OH groups and amide O atoms. Inter-molecular hy-droxy-meth-yl-amide O-H⋯O and amine-hy-droxy-methyl N-H⋯O hydrogen bo...

Biodegradation of s-triazine xenobiotics

Biodegradation of xenobiotic compounds is examined with s-triazines as an example and with biological treatment of wastewater containing striazines as an aim. s-Triazines have been termed recalcitrant, but examination of the literature indicates that a potential for biodegradation exists. Ni t rogenl imi ted enr ichment cultures yield organisms able to degrade by-products of the industrial synt...

Enzymatic degradation of chlorodiamino-s-triazine.

2-Chloro-4,6-diamino-s-triazine (CAAT) is a metabolite of atrazine biodegradation in soils. Atrazine chlorohydrolase (AtzA) catalyzes the dechlorination of atrazine but is unreactive with CAAT. In this study, melamine deaminase (TriA), which is 98% identical to AtzA, catalyzed deamination of CAAT to produce 2-chloro-4-amino-6-hydroxy-s-triazine (CAOT). CAOT underwent dechlorination via hydroxya...

Nitrogen-14 NQR in s-Triazine Derivatives*

Within a study of the temperature dependence of NQR frequencies in some s-triazine derivatives [1], resonance frequencies at 4.2 K were determined in melamine, cyanuric acid, and cyanuric chloride. New lines, which were not reported so far, were detected in two of these compounds. In melamine, nine more lines were found as already described in [4], In cyanuric chloride, two more lines were foun...

Biodegradation of an s-triazine herbicide, simazine

Two types of simazine-degrading microorganisms were isolated from soil samples where the herbicide had been spread with the enrichment culture using simazine as the sole carbon and nitrogen source. A fungal strain, DS6F, identified as Penicillium steckii, is the first simazine-degrading fungus ever reported. Ž Simazine was gradually degraded by P. steckii DS6F in the mineral medium containing s...
