Dimethacrylate polymers with different glycerol content: Thermal study, degree of conversion, and morphological features
(2018-06-01)
The objectives of this study were to verify thermal properties, degree of conversion, and morphological features of several dimethacrylate polymers with different glycerol content and obtain the better proportion system ...
Highly selective acetalization of glycerol with acetone to solketal over acidic carbon-based catalysts from biodiesel waste
(Elsevier Sci Ltd, 2016)
The glycerol acetalization reaction in the presence of acetone was evaluated using acidic carbon-based catalysts from biodiesel waste as catalysts. Acidic carbon-based catalysts were prepared with different glycerin: ...
Use of curcumin and glycerol as an effective photoinitiating system in the polymerization of urethane dimethacrylate
(2017-06-01)
The objectives of this study were to verify the viability of the photoinitiating system using curcumin as a photoinitiator and glycerol as a coinitiator, to analyze the thermal and morphological features of the polymers ...
Ecological efficiency in glycerol combustion
(Elsevier B.V., 2014-02-05)
Growth in biodiesel production has led to a large surplus of glycerol. So the fundamental question arises: What can be done with glycerol? This is one of the main reasons current research is aimed at developing technologies ...
Effect of metal oxide fillers in urethane dimethacrylate polymer with glycerol obtained by photopolymerization synthesis
(2020-10-01)
Urethane dimethacrylate (UDMA) is a monomer widely used in photopolymerization reactions to produce biomaterials, due to its advantageous properties such as mechanical resistance and relatively low viscosity. However, this ...
A comparative study of glycerol dehydration catalyzed by micro/mesoporous MFI zeolites
(2013-04-01)
The catalytic properties of monomodal microporous and bimodal micro-mesoporous zeolites were investigated in the gas-phase dehydration of glycerol. The desilication methodology used to produce the mesoporous zeolites ...

Selective Hydrogenolysis of Glycerol to Propylene Glycol in a Continuous Flow Trickle Bed Reactor Using Copper Chromite and Cu/Al2O3 Catalysts
(Sociedade Brasileira de Química, 2016-12)
The glycerol hydrogenolysis reaction was performed in a continuous flow trickle bed reactor using a water glycerol feed and both copper chromite and Cu/Al2O3 catalysts. The commercial copper chromite had a higher activity ...
Catalytic Synthesis of Monoglycerides by Glycerolysis of Triglycerides
(Berkeley Electronic Press, 2019-09-05)
The synthesis of monoglycerides by the transesterification of triglycerides with glycerol was studied using zinc glycerolate as a heterogeneous catalyst. The effect of the operating variables on the triglyceride conversion ...
