Chemisorption Role of Clay Surfaces in the Synthesis of Porphyrins from its Raw Materials via Room Temperature Reactions [PDF]

open access: yesChemical and Biochemical Engineering Quarterly, 2022
In the formation of porphyrin, at least one step is acid-catalyzed. Cation-exchanged clay was found to be able to provide the acidity needed in the formation of porphodimethine (an intermediate step in the route of porphyrin formation), from the reaction

Effect of production and storage of beer on its sensory stability

open access: yesKvasný průmysl, 2022
Freshly produced beer is in a state of chemical imbalance and its sensory characteristics change and deteriorate over time. The period when beer resists these undesirable changes is referred to as its shelf stability, which is precisely defined from a ...
