Dyeing characterizations of
alkoxide pre-treated acrylic-polyester fibres blend by the use of a cationic dye.
The reaction can be catalyzed by bases (NaOH, KOH, carbonates and corresponding
alkoxides), mineral acids (sulfuric, hydrochloric and sulphonic), solid acid oxides (Ti[O.sub.2], Sn[O.sub.2], ZnO, [Li.sub.4]Si[O.sub.4], [Li.sub.2]Si[O.sub.3], LiAl[O.sub.2] and [Li.sub.2]Ti[O.sub.3]) and either enzymes like lipases [4-12].
The synthesis of the silica support was performed using tetraethyl orthosilicate (TEOS) [Si[(O[C.sub.2][H.sub.5]).sub.4]] as
alkoxide precursor of the Si sol.
Metal
alkoxide Ti[(OBu).sub.4] and ionic liquid MTICl were used to obtain stable homogeneous ionogels via the aqueous sol--gel approach.
This was added to control the hydrolytic activity of zirconium
alkoxide. The solution obtained had a mole ratio of Zr[(O[C.sub.3][H.sub.7]).sub.4]:[H.sub.2]O:AcAc:EtOH of 1:1:4,5:6.
The vast majority of silica aerogels are prepared using silicon
alkoxide precursors.
Photocatalytic treatments on dental mirror surfaces using hydrolysis of titanium
alkoxide. J.
In general, the use of
alkoxide method in sol-gel synthesis involves the formulation of a homogeneous solution containing all of the component metals in the correct stoichiometry [2].
Silicate gels were synthesized by hydrolyzing tetra functional
alkoxide precursor (TMOS), employing a mineral acid, HC1, as a catalyst.
