Surface modification of purified fly ash and application in polymer.

With the growing general concern about the pollution by fly ash (FA), there has been global interest in its utilization. Purified FA or FA micro-beads are suitable as polymer filling materials because of their density, good dispersity and fluidity of globular particles. However, FA as a filler has not been widely used up to now on account of low whiteness values and low friction of untreated FA surface.

[Spectral analysis of the structure of 1, 1'-and 1, 2'-dinaphthyl methanone].

The structure of 1, 1'-and 1, 2'-dinaphthyl methanone synthesized by the reaction of naphthalene with oxalyl chloride in the presence of AlCl3 were studied by using UV and FTIR in this paper. The analysis results showed that the difference of structures (symmetry) of 1,1'-and 1, 2'-dinaphthyl methanone were represented on the obvious difference of the spectra of UV and FTIR.
