‘The synthesis of fluorochemicals from fluorspar with no reliance on the complex supply chain of hydrogen fluoride is one of ...

The chemical industry treats fluorspar with concentrated sulfuric acid at temperatures above 300 °C to produce hydrogen fluoride (HF), which serves as the feedstock for other fluorinating reagents.

Currently, all fluorochemicals - critical for many industries - are generated from the highly dangerous mineral acid hydrogen fluoride (HF). This acid is produced in a high-energy process whereby ...

Formic acid has attracted significant attention as one of the promising hydrogen carriers. In the conventional method, formic acid is first produced from carbon dioxide and hydrogen as a stable ...

This follows previous work by the team into solid-state activation of fluoride using mechanical energy. Their new aqueous reaction pathway is adaptable, depending on the Lewis acid used.

Until now, direct synthesis with iridium catalysts faced challenges due to the rapid decomposition of formic acid into ...

It works by strengthening the tooth’s enamel, its hard outer surface, making it more resistant to the acid produced by bacteria that cause tooth decay. Fluoride also reverses early tooth decay ...

A 2014 study found arsenic, lead, and aluminum in hydrofluorosilicic acid, and aluminum and barium ... ToxFAQs for fluorides, hydrogen fluoride, and fluorine. Centers for Disease Control and ...
