Abstract: This article investigates oligochitosan and low-molecular-weight chitosan, mainly chitosan derivatives that contains bactericidal, growth-stimulating and antifungal properties and are non-toxic to the environment. As these points were considered under world interest, samples of low molecular weight chitosan were obtained by acid hydrolysis of high molecular weight chitosan isolated from Bombyx mori. Research pinpoints and makes scrutinize analyzes on the kinetic regularities of the synthesis of oligosaccharides. It also mentions the rate constant for the formation of low molecular weight (oligo) chitosan Bombyx mori, which is K = 4.6 ? 10-6 g mol / min, was determined depending on the degree of depolymerization of the process on time and from the slope. In conclusion, Structural and physicochemical properties were studied using AFM and IR spectroscopy.
Key words: Bombyx mori chitosan, Bombyx mori oligochitosan, acid hydrolysis, rate constant.
