Abstract:
Nanocellulose is currently receiving a lot of attention due to their properties such as high surface area, stiffness, mechanical strength, thermal stability and high aspect ratio. In this sense, olive pruning residue presents as a promising alternative for the synthesis of nanocellulose due to its cellulose content and high availability. The most common treatment to obtain cellulose nanocrystals is acid hydrolysis with sulphuric acid. For this reason, the purpose of the present study was to determine the optimal conditions for the synthesis of cellulose nanocrystals (CNC) from olive tree pruning (OTP). In this study, the H2SO4 concentration was set at 64%, varying the time (40-120 min) and temperature (40-60 ºC) of the production process. The selection of the optimal conditions was based on the yield of the process, as well as on the properties of the nanocrystals (crystallinity). The selected conditions were 40ºC and 40 min, obtaining a crystallinity of 74% and a yield of almost 64%.
