Usage

Description

Triglycerol, also known as glycerol triesters, is a type of glyceride consisting of glycerol esterified with three fatty acid chains. It is a major component of natural fats and oils and plays a crucial role in various industrial applications.
Used in Pesticide Analysis:
Triglycerol is used as a chromatographic enhancer for analyzing pesticides in tea matrices. It improves the separation and detection of pesticide residues in tea samples, ensuring accurate and reliable results.
Used in Synthesis of (Poly)glycerol Monoethers:
Triglycerol serves as a starting material in the synthesis of (poly)glycerol monoethers, which are valuable compounds with diverse applications in various industries.
Used in Food Industry:
Triglycerol is used as an emulsifier, stabilizer, and texture modifier in the food industry. It helps to improve the consistency, shelf life, and overall quality of food products.
Used in Cosmetics and Personal Care Industry:
Triglycerol is used as a moisturizing and conditioning agent in cosmetics and personal care products. It helps to maintain skin hydration and improve the texture of hair and skin.
Used in Pharmaceutical Industry:
Triglycerol is used as a solvent, carrier, or excipient in the pharmaceutical industry. It aids in the formulation and delivery of various drugs and medications.
Used in Biodiesel Production:
Triglycerol is a key component in the production of biodiesel, an environmentally friendly and renewable energy source. It is converted into biodiesel through a process called transesterification, which involves the reaction with an alcohol and a catalyst.

Glycerol valorization by etherification to polyglycerols by using metal oxides derived from MgFe hydrotalcites

This work investigates the use of MgFe mixed oxides, derived from layered double hydroxides (LDH) with Mg/Fe molar ratio ranging from 1 to 4, as base catalysts for the etherification of glycerol. LDH precursors and catalysts were characterized by XRD, XPS, CO2-TPD, NH3-TPD, N2 adsorption and DTA-TG analysis. The MgFe mixed oxides exhibit excellent textural properties, with specific surface areas close to 200 m2 g-1 and average pore diameters in the mesoporous range. This family of catalysts has shown to be active in the formation of polyglycerols from glycerol without solvent, at 220 C, in a batch reactor. The highest conversion (41%) is found for the MgFeO4 catalyst prepared with a Mg/Fe molar ratio of 4, whereas full selectivity to diglycerols is only reached for the MgFeO1 catalyst. Only diglycerols (DGs) and triglycerols (TGs) have been detected after 24 h of reaction.

Heterogeneously catalyzed etherification of glycerol to diglycerol over calcium-lanthanum oxide supported on MCM-41: A heterogeneous basic catalyst

The catalytic etherification of glycerol using calcium-lanthanum oxide supported on MCM-41 as a stable heterogeneous basic catalyst was investigated. Stable heterogeneous mesoporous basic catalysts were synthesized by wet impregnation of MCM-41 with calcium nitrate and lanthanum nitrate. The surface and structural properties of the prepared catalysts were when characterized using different techniques. MCM-41 and modified MCM-41 were used in the solventless etherification of glycerol to produce diglycerol as the desired product. The reaction was performed at 250 °C for 8 h, and catalyst activity was evaluated. Catalytic etherification over the 20%Ca1.6La 0.6/MCM-41 catalyst resulted in the highest glycerol conversion of 91% at the diglycerol yield of 43%. The distribution of diglycerol isomer in the etherification of glycerol was studied, and the value of the sum of two dimers (ββ′ + αβ = 67%) was found to be higher than that of αα′ dimer (33%) after 8 h of reaction. Thus, the major reaction occurred inside the porous area instead of the external surface area.

V- or Mo-modified niobium catalysts for glycerin conversion reactions in the presence of H2O2

In the present work, amorphous niobium oxides with 5% (w/w) vanadium or molybdenum isomorphically substituted into the material structure were synthesized. The materials were characterized by X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy coupled with energy-dispersive X-ray spectroscopy (SEM/EDS), transmission electron microscopy (TEM), and X-ray photoelectron spectroscopy (XPS). The results show that vanadium and molybdenum were incorporated into the niobium oxide structure with concomitant changes in the morphologic and catalytic properties. Catalytic studies on the conversion of residual glycerin generated during biodiesel production in the presence of H2O2 showed enhanced efficiency of ether formation with the vanadium-containing material. The NbV/ethanol/glycerin/250 °C system was found to convert 80% of glycerin. Experiment-planning studies in conjunction with the analysis of the surface response via gas chromatography-mass spectrometry (GC-MS) aided in the determination of the optimal conditions. The catalytic tests monitored by GC-MS showed the formation a mixture of ethers obtained by the condensation of glycerol. Furthermore, it was observed that the modification of the catalyst directs the formation of larger molecules such as ketone mainly in the catalyst containing vanadium.
