摘要 |
The present invention relates to a bio-based glutaraldehyde compound and to the different non-fossil, natural raw material manufacture methods thereof. To prepare said compound, glycerol created by the methanolysis of vegetable oil or animal fat is used, leading after dehydration to acrolein that is caused to react with a vinyl/alkyl/ether as per a Diels-Alder cyclization reaction, followed by hydrolysis so as to obtain the bio-based glutaraldehyde of the invention. Sugars containing five carbon atoms, that is, pentoses created from for example hemicellulose, may also be used, leading after dehydration to furfural, which leads, after complete hydrogenation followed by selective oxidation, to the bio-based glutaraldehyde of the invention. |
