Claim 4:
5. A process for the preparation of a non-hygroscopic, recyclable,
and thermally stable complex according to claim 1, the process comprising:
(a) adding a polysaccharide support and tetra-n-butyl ammonium fluoride hydrate at a w/w ratio of 1:0.3 to 1:6 in hexane to obtain a mixture;
(b) refluxing the mixture obtained in (a) under inert atmosphere at 80° C. for 1.5 hours with vigorous stirring to obtain a solution;
(c) cooling the solution obtained in (b) to 25-30° C., filtering, washing with hexane followed by drying under high vacuum to obtain the non-hygroscopic, thermally stable complex.
