Abstract

This thesis describes the synthesis of a novel anhydride that could theoretically be used to
strengthen cellulose fibres in terms of their water resistance for potential use as a potential green
replacement for fibreglass. The first chapter, the introduction, is split into 3 parts which are the 3
constituent parts to the novel anhydride molecule, the PEG, the cellulose and the linseed oil.
The first part of the introduction highlights the uses of PEGs in industry now, with its flexibility and
hydrophilicity resulting in its use in a wide range of products varying from cosmetics to hydraulic
fluid.
The second part of the introduction describes the cellulose fibres and its vast potential usefulness
due to its abundance. Furthermore, its current uses are explored, with uses in the Pharmaceutical
industry among other things.
The third part to the introduction deals with the synthesis of the linoleic (and other unsaturated
long-chain hydrocarbons) alcohol and how its unsaturated bonds can cross-link to form hydrogen
bonds between individual hydrocarbons. Crosslinking between inter-molecular bonds is theorized to
occur between the cellulose and the unsaturated hydrocarbon as well.
The second chapter is the results and discussion which describes the results of the experimental
procedures of this thesis. Due to the difficulties of collecting the pure ether during the Williamson
ether synthesis stage, the practical side of the thesis was stalled at the formation the ether step.
However, spectroscopically pure Linoleyl Bromides, Tosylates and Mesylates were all produced as
was the pure monoprotected trityl PEGs.
The third and final chapter contains the experimental data for the compounds produced in the
previous chapter.
