In 2020,BioResources included an article by Kravetz, Carolina; Leca, Carlos; Brito, Jose Otavio; Saloni, Daniel; Tilott, David C.. Category: tetrahydrofurans. The article was titled 《Characterization of selected pyrolysis products of diseased orange wood》. The information in the text is summarized as follows:
Orange trees in Brazil are often burned as a means of eradication when they become infected with Huanglongbing disease. Rather than destroying them, which is a low-value proposition, one potential option is to utilize the biomass through pyrolysis. In this preliminary work, orange trees (Citrus sinensis) otherwise selected for purging, were sampled and pyrolyzed at 500 °C, and the charcoal and bio-oil were evaluated for potential value-added use. The results showed that the pyrolysis process resulted in 26.3% charcoal, 57.6% bio-oil, and 16.0% non-condensable gases. Qual. anal. of the bio-oil by gas chromatog./mass spectrometry found 178 chem. compounds; however, only 25% of those compounds could be reliably identified. Potential applications of the compounds identified in the bio-oil were determined by examining the published literature, and it was found that at least 73% of them showed promise. Finally, initial studies on the immediate anal. of the pyrolysis charcoal showed that it potentially meets the standards set forth for Brazilian domestic use. In the part of experimental materials, we found many familiar compounds, such as 3-Hydroxydihydrofuran-2(3H)-one(cas: 19444-84-9Category: tetrahydrofurans)
3-Hydroxydihydrofuran-2(3H)-one(cas: 19444-84-9) is a 5-membered cyclic ester. It was obtained via tin-conversion of biomass-derived 1,3-dihydroxyacetone (DHA) and formaldehyde. And it may be employed as starting reagent in the synthesis of series of seco-pseudonucleoside synthons via aminolysis.Category: tetrahydrofurans
