XXXIV.—The oxidation of mannitol by nitric acid. d.-Mannosaccharic acid

Modifications in the nitric acid oxidation of D-glucose.

The nitric acid oxidation of D-glucose was reinvestigated in an effort to better understand and improve the oxidation and subsequent work up steps. The oxidation was carried out using a computer controlled reactor employing a closed reaction flask under an atmosphere of oxygen which allowed for a catalytic oxidation process with oxygen as the terminal oxidant. Removal of nitric acid from produc...

Kinetic, mechanistic and thermodynamic investigations on Iridium (III) catalyzed oxidation of D-Mannitol by N-chloro-p-toluenesulfonamide in perchloric acid medium

The present paper deals with the kinetics and mechanism of homogeneously Ir(III) chloride catalyzed oxidation of D-mannitol by chloramine-T [CAT] in perchloric acid medium in the temperature range of 30 to 45 0C. The reaction is carried out in the presence of mercuric acetate as a scavenger for chloride ion. The experimental results show first order kinetics with respect to the oxidant [CAT] an...

THE OXIDATION OF HEXOSAMINES : d-GLUCOSAMINE AND d-GLUCOSAMINIC ACID

Atomistic oxidation mechanism of a carbon nanotube in nitric acid.

Motivated by recent experiments, we investigate how NO3-SWNT interactions become energetically favorable with varying oxidation state of a single-walled carbon nanotube (SWNT) using first-principles calculations. Chemisorption becomes less endothermic with respect to physisorption when the SWNT oxidation state is elevated. Importantly, the dissociative incorporation of an oxygen atom into the S...

Nasal burn by nitric acid.

A 33 year old woman dropped in her nose a product based on nitric oxide, known as “strong water” and professionally used by her husband. The bottle with the acid was mistaken for the bottle of a topical nasal decongestant. She complained of intense pain, burning sensation, nasal obstruction and tearing. Rhinoscopy showed a burn on the nasal wing and on the nasal vestibule, of yellowish color, s...
