The synthesis of 1,2-propylene glycol acetals of 3-alkoxy-4-acyloxybenzaldehydes by condensation of 3-alkoxy-4-acyloxybenzaldehydes with 1,2-propylene glycol in boiling benzene in the presence of the FIBAN K-1 sulfonic cation-exchange resin is reported. In the experiment, the researchers used many compounds, for example, 4-Formyl-2-methoxyphenyl isobutyrate (cas: 20665-85-4Application of 20665-85-4).
4-Formyl-2-methoxyphenyl isobutyrate (cas: 20665-85-4) belongs to esters. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Application of 20665-85-4
