Application and pharmacology Aluminum chloride is a chemical compound with the chemical formula AlCl3. When contaminated with iron chloride, it often displays a yellow color compared to the white pure compound. It is used in various chemical applications as a Lewis base, with anhydrous aluminium tri...

where they are converted into fermentable feedstocks via the addition of oxygen and alkali (NaOH). Besides bio-ethanol and bio-butanol, other useful chemicals are produced. The heart of the process is the GPV, which consists of sterile, double-isolated vertical tube having a length of approximat...
Monomeric stibine oxide has remained elusive due to the large antimony orbitals coupled with a high electronegativity difference with oxygen. Now, a free tris(2,6-diisopropylphenyl)stibine oxide has been isolated that can act as oxo-transfer reagent. Moumita Majumdar Article | 27 March 2023 Is...
