Solid Lewis-base catalysis is important in the production of fine chems. A Lewis-base Ga4B2O9 was synthesized by high temperature solid state reactions. It exhibited a high yield (90%) and a high stability in Knoevenagel condensation reactions, where several aldehydes were combined with malononitrile to form α,β-unsaturated compounds through nucleophilic addition reactions. Reaction kinetics analyses indicated Knoevenagel condensation reactions over Ga4B2O9 catalyst obeyed a second-order characteristics and the calculated activation energy was â?1.6 kJ/mol, suggesting that Langmuir-Hinshelwood absorption pathway was probably employed. The structural evolution from Ga4B2O9âGaBO3âÎ?Ga2O3 evidenced that the structure-induced basicity of Ga4B2O9 attributed to the special μ3-O atoms linked exclusively to 3 five-coordinated Ga3+. This investigation proves a convincing structure-property correlation in Ga-based solid base materials and helps developing an alternative avenue towards the design of new intrinsic solid base catalysts. In the experimental materials used by the author, we found 3-Hydroxybenzaldehyde(cas: 100-83-4Formula: C7H6O2)
3-Hydroxybenzaldehyde(cas: 100-83-4) is used as an ionophore, during the development of an highly selective and sensitive PVC membrane sensor, which can be used as a Tb3+ ion selective electrode.Formula: C7H6O2
