Two cases of hydrazine hydrate dermatitis without systemic intoxication.
Hydrazine hydrate is an irritant which readily vaporizes. The irritant effects are not immediately noticeable. They develop gradually over several hours (Byrkit and Michalek, 1950). The local effects are inflammation of the skin and of the mucous membranes of the upper respiratory tract and eyes. Krop (1954) reports the occurrence of hydrazine dermatitis. Individual susceptibility to dermatitis...
متن کاملSynthesis of Graphene Oxide using Modified Hummer’s Method and its Reduction using Hydrazine Hydrate
Graphene is a hot area of research because of its unique and remarkable properties. These properties have invoked researchers to use this form of carbon in various potential applications. One of the bottlenecks in developing such application is mass production of graphene. Hummer’s Method is one of the easiest and economical methods to synthesize huge amount of reduced graphene oxide (RGO) shee...
متن کاملMutation Breeding of Lipase-producing Strain Flavobacterium sp. by Supercritical CO2 with Hydrazine Hydrate
This work aimed to obtain an ideal mutant strain with higher lipase yield using hydrazine hydrate (HZH) as a novel additive to treat Flavobacterium sp. strain YY25 by supercritical CO2. The survival rate and the positive mutation rate of the tested strain were strongly dependent on the dose of HZH. The treatment by 0.5% HZH in supercritical CO2 (8 MPa, 35°C) for 30 min provided 58.3% of positiv...
متن کاملH-Bonding and charging mediated aggregation and emission for fluorescence turn-on detection of hydrazine hydrate.
In situ morphological transition and turn-on fluorescence of self-assembled NDI derivatives driven by hydrazine hydrate are realized through H-bonding and charging of aromatic building blocks, demonstrating a stimuli-responsive supramolecular system useful for visual detection of hydrazine hydrate.
متن کاملThe reaction of ethyl 2-oxo-2H-chromene-3-carboxylate with hydrazine hydrate.
Although salicylaldehyde azine (3) was reported in 1985 as the single product of the reaction of ethyl 2-oxo-2H-chromene-3-carboxylate (1) with hydrazine hydrate, we identified another main reaction product, besides 3, which was identified as malono-hydrazide (4). In the last two decades, however, some articles have claimed that this reaction afforded exclusively hydrazide 2 and they have repo...
