WebThe present investigation describes the preparation of nano-SiO2-phenolic novolac resin nanocomposite through in situ polymerisation. CP MAS 13C NMR and FTIR analyses indicate the formation of chemical linkage between the inorganic and organic components. The decomposition temperature of the nanocomposite is ∼70 °C higher than the neat … Web1. júl 2024 · A carboxylate ion (see figure below), in which the negative charge is spread over two different oxygen atoms through resonance structures, is more stable than an isolated oxygen-centered anion. Carboxylic acids are used in a variety of environments. Formic acid acts as a protective chemical for many stinging insects and plants.
