A new method for quantifying glycerol, lactic acid, and the by-products (pyruvaldehyde) obtained in this reaction was developed using high-performance liquid chromatography (HPLC) with a refractive index detector (HPLC-RI) in a column (300 × 7.7 mm, 8 µm) using H2SO4 0.001 M + 10% ACN (organic modifier) as mobile phase (0.6 mL min–1). This method indicated outstanding linearity for glycerol and lactic acid concentration from 0.6 to 6.6 g L–1 (coefficient of determination (R²) = 0.9912 and 0.9961, respectively) and accuracy between 98.33 and 100.00%. From this, it was possible to conclude that the method is applicable and concise for separating the primordial products in this reaction. 2022 artículo científico 0100-4670 https://www.redalyc.org/articulo.oa?id=42970797004 https://www.redalyc.org/journal/429/42970797004/ https://www.redalyc.org/journal/429/42970797004/html/ https://www.redalyc.org/journal/429/42970797004/42970797004.epub https://www.redalyc.org/journal/429/42970797004/movil https://doi.org/10.26850/1678-4618eqj.v47.2.2022.p74-81 en http://www.redalyc.org/revista.oa?id=429 Eclética Química application/pdf Universidade Estadual Paulista Júlio de Mesquita Filho Eclética Química (Brasil) Num.2 Vol.47 |
