Perfluoro (Imidoylamidine) diamidines [PDF]

, 1986
Perfluoroether triazine elastomers having improved properties are prepared from oligomeric imidoylamidines that were in turn, prepared by the process of: (1) reacting a perfluorodinitrile with liquid ammonia to yield a perfluorodiamidine, (2) isolating ...

Supramolecularly Directed Confined Crystallization of Lamellar Carbon Nitride for Efficient Photocatalytic Hydrogen Generation

Advanced Energy Materials, EarlyView.
ABSTRACT Sustainable hydrogen generation through water splitting is key to realizing a future hydrogen economy. In this study, we achieved molecular‐level control over self‐assembled supramolecular complexes of cyanuric acid and 3‐amino 1,2,4 triazole (AT) monomers. This was coupled with molten‐salt‐assisted thermal polymerization in a eutectic mixture

Metodologias eletroanalíticas para a determinação de herbicidas triazínicos por voltametria de onda quadrada e técnicas de deconvolução Electroanalytical methodologies for the determination of triazine herbiacides by square wave voltammetry and deconvolution techniques

Química Nova, 2007
This work describes the development of electroanalytical methodologies for the determination of atrazine, ametrine and simazine by square wave voltammetry on a mercury electrode. For pure atrazine and pure ametrine, the detection limits (DL) were 3.7 and

Influência do estádio de desenvolvimento de Cenchrus echinatus na supressão imposta por atrazine Effect of the growth stage of Cenchrus echinatus on weed suppression imposed by atrazine

Planta Daninha, 2011
Cenchrus echinatus é uma importante infestante em áreas de cultivo de milho, sorgo e milheto no Brasil. Embora atrazine seja um dos herbicidas mais utilizados nessas culturas, pouco tem sido feito para determinar a suscetibilidade dessa espécie em função

Development of a Mild and Versatile Directed Cycloaddition Approach to Pyridines [PDF]

, 2014
The aza-Diels–Alder cycloaddition of 1,2,4-triazines with alkynes offers a rapid and convenient method for the synthesis of highly substituted pyridines, but often requires harsh conditions and long reaction times.

Determination of triazines in hemodialysis saline solutions by adsorptive stripping voltammetry after extraction in acetonitrile

Journal of the Brazilian Chemical Society, 2003
A method for the voltammetric determination of 2-methylthio-4,6-dialkylamino-1,3,5-triazine (triazines) herbicides in hemodialysis (HD) saline solutions was developed.

Mechanism of Hydrogen Sulfide Generation and Prevention Strategies in Oil and Gas Fields: A Case Study of the Sickle Bay Operation Area

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT To address the persistent exceedance of hydrogen sulfide (H2S) concentrations and the limited effectiveness of existing treatments in the Sickle Bay oil production area, this study deeply analyzes the mechanism of H2S generation in the Sickle Bay oil production area and proposes targeted prevention and control strategies. The results show that
