Optimiranje postopka toziliranja lesa in substitucija tozilatnih z amino skupinami : diplomsko delo (univerzitetni študij) = Optimisation of wood tosilation process and substitution of tosylate groups with amino groups : graduation thesis (university studies)
Šek, Matej
Razvili smo postopek za optimalni navzem tozil klorida v zmesi aceton : piridin. Z uravnavanjem temperature, časa trajanja postopka in koncentracije topila, smo optimirali navzem reagenta. Nastale ...tozilatne skupine služijo kot reaktivno mesto za nadaljnjo nukleofilno substitucijo na primarnem, sekundarnem in terciarnem mestu molekule celuloze. Za substitucijo tozilatnih skupin smo uporabili amino skupino v vodni raztopini amoniaka. Analizo vezave reagenta in obseg substitucije smo preverili z merjenjem navzema (WPG), CSN analizo ter FTIR spektroskopijo. Toziliran les predstavlja intermediat za kemijsko modifikacijo lesa, kjer naj bi bil končni namen hitinizacija lesa.
