Health Effects of a Hydrogen Fluoride Emitting Glass Fibre Plant in the NetherlandsThe health effects of a glass fibre plant, emitting 12-15 kg HF/hr, were studied in a village close to the plant. A village upwind at 15 km distance served as control in the study. The socioeconomic data ...
Health Hazards Hydrofluoric acid has irritating smell and acute toxicity, belonging to the medium strength & slightly weak acid. It is corrosive. It is commonly used in the manufacture of fluorocarbon, sodium fluoride, aluminum fluoride, uranium hexafluoride and cryolite and other organic or inorganic...

Explodes when heated with calcium carbonate + magnesium; 3,4-dichloronitrobenzene + catalysts; vegetable oils + catalysts; ethylene + nickel catalysts; difluorodiazene (above 90°C); 2-nitroanisole (above 250°C/34 bar + 12% catalyst); copper(II) oxide; nitryl fluoride (above 200°C); ...
Simplified procedure for carrying out simultaneous multiple hydrogen fluoride cleavages of protected peptide resins. Methods have recently been presented which greatly increase the ability to synthesize large numbers of peptides. These advances make it essential to be abl......
The process involves treating the carbon with a fluorine acid solution which consists of an aqueous solution of hydrofluorosilicic acid and hydrogen fluoride, such that the available metal oxides are converted to metal fluorides and/or metal fluorosilicates and separating the treated carbon from the...
