Реферат:
The influence of temperature on the conversion of ethanol-lignin in supercritical ethanol and on the yield and composition of the products formed was studied. In the absence of catalysts, the highest yield (60 wt.%) of liquid products of thermal conversion of ethanol-lignin was obtained at the temperature of 300 degrees C. According to GC-MS data, the ethanol-soluble products mainly consist of phenols, methoxyphenols and ethyl esters of carboxylic acids. The increase of the temperature of ethanol-lignin conversion to 400 degrees C intensifies the transformation of liquid ethanol-soluble products into solid and gaseous substances and leads to a decrease in ethanol-soluble products the content of methoxyphenols by 3 times and of carboxylic acid esters by 2 times. The use of catalysts, based on borate-containing alumina in the process of ethanol-lignin conversion in a supercritical ethanol at the temperature 300 degrees C increases the yield of products, boiling up to 180 degrees C by 3,4-3,6 times and rises the yield of methoxyphenols by 1,4-1,7 times in comparison with a non-catalytic process.
