Description
Pavel Kaule and co-authors test cage like boron acids as catalysts in a 2024 paper. Turning fatty acids into esters with alcohol now leans on sulfuric acid, which corrodes gear and adds waste. The team made halogen laced cobalt bis-dicarbollide acids, a class of strong cluster acids never used this way before.
Six new forms were built and checked by a battery of lab methods. One chlorine form proved the best catalyst for four fatty acids in hot alcohol, and it could be reused. Sieves soaked up water to drive full change. Dye and sodium tests set its acid strength beside sulfuric acid for a fair gauge.
