Agrifood byproducts are perfect candidates to be further processed under the concept of circular economy, in order to produce their valorization. Although significant amounts of food-related wastes that are discarded are produced worldwide, these might still be rich in valuable compounds A strategy to further valorize agrifood-related byproducts is based on pyrolysis processes. The result of this process is a liquid product termed bio-oil which is composed of an organic phase and an aqueous phase. This bio-oil is rich on a variety of components and its anal. implies several challenges. In this work, quant. online comprehensive two-dimensional liquid chromatog. (LC × LC) is proposed for the first time to characterize several aqueous phases of different bio-oils. Rice husk, peanut shell, spent coffee grounds, peach core and Eucalyptus sawdust biomasses were analyzed. The developed quant. LC × LC method presented very good linearity, precision, reproducibility, recovery and LODs and LOQs as low as 0.05 μg mL-1 and 0.16 μg mL-1, resp. As much as 28 components were simultaneously separated and quantified in those samples. Our results found that the composition of these bio-oils was different but strongly related to the agrifood byproduct submitted to pyrolysis. The developed methodol. is foreseen as a valuable tool for the quant. study of other bio-oils, considering the great complexity and high dimensionality of these samples. This study involved multiple reactions and reactants, such as 4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1Application of 2380-78-1).
4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1) belongs to ethers. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Application of 2380-78-1
