| Résumé : |
Formic, phosphoric and nitric acids were used for hydrolysis of the commercially available hydrolysis product of chrome shavingshykol-E. The aim of the work was to prepare low-molecular weight product (Mw<5000g.mol-1) to be used as the plant bio-stimulator. Course of hydrolysis was monitored by following the changes of molecular weight (MW) and molecular weight distribution (MWD) determined by gel permeation chromatography (GPC). The study demonstrated that MW and MWD of hydrolysates are influenced by the choice of hydrolysing acid, its concentration as well as by the time of acid treatment. Using the combination of enzymatic and acid hydrolysis, it is possible to prepare products with the tailor-mad, pre-defined molecular weight fitting the intended use. |
