The FTIR spectrum of untreated dyes effluent exhibited peaks at 3344.59, 2352.21, 1646.3, 619.15 and 613.956 cm-1 for -OH stretch of phenol, N=N stretch and C=C stretching of monosubstituted
benzene ring (Fig.
The core-shell composite particle containing PS was confirmed by the strong absorption peaks at 1,600, 1,492 [cm.sup.-1] (the C=C stretching of benzene-rings), 754, and 699 [cm.sup.-1] (the out-of-plane bending of C-H of monosubstituted
Further, the reaction consists of three stepwise or consecutive reactions that involve formation of two monosubstituted
and two disubstituted intermediates before reaching to the final product D (Eq.

benzene rings: an ab initio MO study," Journal of Physical Chemistry A, vol.
Conventional phosphorylation could produce monosubstituted
phosphate monoester starch or cross-linked phosphodiester starch.
Compounds 1a and 1b gave vinylic substitution reaction at room temperature and with the absence of solventbecause of the reactivity of terminal carbon having nitrodichlorovinyl, and they yielded monosubstituted
polyhalobutadiene compounds 3a  and 3b .
The peak at 7.43 ppm in [sup.1]H NMR and the several peaks at 125 ppm-135 ppm in [sup.13]C NMR could testify to the existence of the monosubstituted
Formation of ettringite from monosubstituted
calcium sulfoaluminate hydrate and gypsum.
Vertical ionisation potentials of benzene and some of its monosubstituted
and 1,4-disubstituted derivatives.
Finally, a DFT study reveals that the formation of 1-4 is thermodynamically favoured with respect to a tentative isolation of the monosubstituted
products 1'-4' because of the use of mw conditions.
Hence, [WA-f.sub.50] and [WB-f.sub.75] had significantly different inhibition potency towards [alpha]-glucosidase activity despite having similar relative proportions unsubstituted (un-Xylp), monosubstituted
, (2-Xylp or 3-Xylp), and disubstituted xylose residues (2,3-Xylp) and degree of substitution but different ferulic acid content.
