The double bonds can easily be epoxidized, and if hydroxyl groups are required, the epoxidation procedure is usually followed by alcoholysis
to form the polyols.
of Vegetable Oils for Production of Biodiesel Fuel
And the alcoholysis
degree of PVA powder (BP-26 for industrial use) was 88%, this powder was good solubility in water.
These organosilica hybrid materials with crystalline mesoporosity, tailored through organic chemistry to be mono-, hi- or tri-functional, offer unique potential for scientific and technological advances in numerous application areas because the organic function and the inorganic framework can be tailo red through chemistry to tune their mechanical, electrical, optical, magnetic, catalytic, separation and chemical reactivity properties (see the group's recent paper 'Novel Bifunctional Periodic Mesoporous Silicas, BPMOs -- Synthesis, Characterization, Properties and in situ Selective Hydroboration -- Alcoholysis
of Functional Groups', Journal of the American Chemical Society, 123, 8520-8530, 2001).
It is the only water soluble high molecular polymer currently known, and is polymerized by vinyl acetate (VAM) through alcoholysis
Indeed, as acid, ester, alcohol, and carbonate functions are available, transesterifications, alcoholysis
, acidolysis, and carbonate-ester functions can happen.
The chemical recycling of waste PET can be carried out in many ways such as glycolysis, hydrolysis, alcoholysis
, simultaneous hydrolysis-glycolysis, aminolysis, and aminoglycolysis [7, 8, 10].
Possible transreactions for polyesters and polyamides are depicted in Scheme 1 and include alcoholysis
, transesterification, aminolysis, and amidolysis.
The Methanol and FFA's can be added to the alcoholysis
reaction to reduce the biodiesel production cost.
During the alcoholysis
or transesterification stage, the oil, polyol.
An aliphatic polyester is melt-blended with an alcohol to initiate an alcoholysis
reaction resulting in hydroxyalkyl or alkyl terminal groups and lower molecular weights.
Biodiesel production takes place throughout an alcoholysis
reaction known as transesterification, where triglycerides with an alcohol and a catalyst react to generate esters of the alcohol called biodiesel, and glycerol as a by-product .
