This study reports the preparation of hydrotalcite with Mg/Al molar ratio 3 by co-precipitation under low suprasatn. conditions of Mg and Al nitrated solutions with Na2CO3 and NaOH at pH 10. The solid was thermally decomposed at 460° in air atm. in order to obtain mixed oxides which, by means of memory effect, can reconstruct the hydrotalcite structure by hydration with bi-distilled water. The hydrotalcite and reconstructed samples by memory effect were characterized by elemental anal., powder x-ray diffraction, DRIFT and TG-DTG. Determination of the catalysts surface base sites was made using a method based on the irreversible adsorption of organic acids with different pKa values and N2 adsorption-desorption isotherms. The catalytic activity of these solids was evaluated in 1,4-addition of saturated linear alcs. to different acrylic compounds All these reactions arose with high selectivity in the desired product. No byproducts were detected by means of GC-MS chromatog. and 1H NMR. This study involved multiple reactions and reactants, such as Ethyl 3-ethoxypropanoate (cas: 763-69-9Category: esters-buliding-blocks).
Ethyl 3-ethoxypropanoate (cas: 763-69-9) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits. 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.Category: esters-buliding-blocks
