Some of the most commonly used processes for HPA production include alkoxide
process, thermal decomposition process, choline hydrolysis process, and modified Bayer process.
The primary OH groups on chitosan react with (CH3)3CO-K+, which is a basic compound, to form chitosan alkoxide
. In another reaction, the chitosan alkoxide
reacts with methacryloyl chloride to form chitosan methacrylate (Cts.met).
Dyeing characterisations of alkoxide
pre-treated polyester/acrylic fibres blend by the use of a cationic dye in one bath by two steps is also studied by El-Gabry and Bendak (2006).
This suggests the complete decomposition of organic residues derived from alkoxide
formation, as shown at Scheme 2.
These variables are the mechanism to disperse Ti alkoxide
species in an appropriate medium allowing the hydrolysis-condensation processes, dipping time, and number of coating cycles (dip + drying + calcination).
To the resultant alkoxide
, mesylate 2 (19.2 g, 61.7 mmol) was added and the reaction mixture was heated at 90[degrees]C for 8 h.
(D) Commercial high-purity alumina nanopowder is manufactured from aluminum metal and alcohol, producing high-purity aluminum alkoxide
, after which hydrated alumina is produced by the hydrolysis of aluminum alkoxide
, with consequent calcination  (Sumitomo Chemical).
After heating the mixture of two ionic liquids and metal alkoxide
for 12 h under Ar atmosphere, selected P-IL gels with dispersed functionalized metal oxide nanoparticles were obtained.
The process involves hydrolysis and condensation reactions of metal alkoxide
precursors in a water-alcohol solution (sol), which lead to the formation of a 3D network (gel) .
material mostly soluble in alcohol, easily purified, and the synthesis of materials with high purity, and is in the state of low viscosity liquid mixing raw materials, chemical reactions in solution to the ceramic obtained uniform, fine and dense, can get highly uniform group divided into oxide coating, is conducive to the preparation of composite oxide.
Al., it is clear that on adding aqueous sodium hydroxide to the natural fibre, the ionisation of hydroxyl group found in fibre to alkoxide
group is achieved.
Ring opening relieves the small amount of ring strain that is present and creates a new alkoxide
nucleophile which can attack another lactide monomer, allowing the polymerization to proceed.
