Nitrification Inhibition Using Benzotriazoles
ABSTRACT The common corrosion inhibitor, 1H-benzotriazole (Bz), found as a component of glycol-based aircraft deicers, and its derivatives such as 5-chloro-1H-benzotriazole (CBz), 1-hydroxy-benzotriazole (HBz), and 5-methyl-1H-benzotriazole (MBz), are all potential nitrification inhibitors. The inhibitory effect on the nitrification of urea-N fertilizer in agricultural soils was examined over a...
متن کاملBenzotriazoles: Toxicity and Degradation
Benzotriazole and methyl benzotriazole were studied in soil, water, and wood. As reported by various authors, benzotriazole is highly stable in soil or water. It was also found to be a potent inhibitor of plant growth, killing several species at levels of about 0.1 mg/ml. Both benzotriazoles are readily degraded by the Fenton reaction; they are also degraded slowly in the presence of horseradis...
متن کاملNTP Research Concept: Phenolic Benzotriazoles
These chemicals are used as UV stabilizers within products to increase stability to light. As industrial additives, they are used in paints, rubber, plastic, and electronic products. Some PBZTs are used in food contact polymers and adhesives, cosmetics, sunscreens, and fragrances. Generally speaking, the class is made up of chemicals with single substitutions on the phenolic ring (R2), double s...
متن کاملDeproto-metallation using a mixed lithium-zinc base and computed CH acidity of 1-aryl 1H-benzotriazoles and 1-aryl 1H-indazoles.
1-Aryl-1H-benzotriazoles and -1H-indazoles were synthesized, and their deproto-metallation using the base prepared by mixing LiTMP with ZnCl2·TMEDA (1/3 equiv.) was studied. In the indazole series, reactions occurring at the 3 position were followed by ring opening, and functionalization of the substrate was only found possible (on the sulfur ring) using 2-thienyl as aryl group. In the benzotri...
متن کاملSeasonal source influence on river mass flows of benzotriazoles.
The anticorrosive agents 1H-benzotriazole (1H-BT), 4-methyl-1H-benzotriazole (4 Me-BT) and 5-methyl-1H-benzotriazole (5 Me-BT), which are usually added to dishwasher detergents, automotive antifreeze formulations and aircraft de-icing/anti-icing fluids (ADAFs), were measured in river water. Samples were collected from 15 sampling sites in the mainstream and selected tributaries of a medium-size...
