Glycerol carbonate synthesis via Zn(OBu)2/AlCl2(OBu) initiated-glycerolysis of urea

Chemistry of Inorganic Materials
Glycerol carbonate (4-hydroxymethyl-1,3-dioxolane-2-one) was efficiently synthesized from glycerolysis of urea initiated by Zn(OBu)2/Al(OBu)Cl2. The zinc-aluminum complex mixture was prepared from zinc chloride (ZnCl2) and aluminum tri-sec-butylate (Al ...

A Comparison of Monoglyceride Production from Microalgaelipids and Rapeseed Oil Catalyzed by Metal Oxides. [PDF]

ChemSusChem
Microalgae is an underutilised source of food with high nutritional value, such as omega 3, −6, and −9. Glycerolysis of microalgal oil is a simple route to obtain emulsifiers rich in these essential fatty acids and this study reports the first use of heterogeneous catalysts for this application.

From liquid to solid: Exploring techniques, applications, and challenges of structured oils as fat replacements in food formulations. [PDF]

Compr Rev Food Sci Food Saf
Abstract Oil structuring is a strategy used to change the physical state of liquid oils to mimic the behavior of solid fats. In the past years, following the legislative bans on using partially hydrogenated fats and recommendations on limiting saturated fatty acid intake, oil structuring has become a fast‐developing research area.

Use of Crude Glycerol for Glycerolysis of Free Fatty Acids in Crude Palm Oil

International Journal of Technology, 2021
The glycerolysis of crude palm oil (CPO) using potassium hydroxide was studied. This work aimed to evaluate free fatty acid (FFA) conversion in CPO through glycerolysis using crude glycerol.

Study of glycerolysis of lactic acid

IOP Conference Series: Materials Science and Engineering, 2020
Abstract Increasing production of a biodiesel industry, will also increase the by-product of the industry, glycerol. Further processes were investigated to get an added value of the byproduct. Glycerol esters of lactic acid and in particulars glycerol monolactate is one of the more value of derivative material from glycerol, which is ...

Base Catalyzed Glycerolysis of Ethyl Acetate [PDF]

Organic Chemistry: Current Research, 2012
Glycerol is a simple polyol compound widely used as a green solvent, having backbone to all lipids known as triglycerides. In our present study, we used glycerol as an acyl acceptor for transesterification of aliphatic acetate by conventional and using microwave assisted synthesis.

Purification of Residual Glycerol from Biodiesel Production as a Value-Added Raw Material for Glycerolysis of Free Fatty Acids in Waste Cooking Oil

Energies, 2022
The crude glycerol produced as a byproduct of transesterification synthesis has very few applications because it comprises of significant amounts of methanol, catalyst, and soap.

Lipase‐mediated plant oil hydrolysis—Toward a quantitative glycerol recovery for the synthesis of pure allyl alcohol and acrylonitrile

European Journal of Lipid Science and Technology, Volume 125, Issue 9, September 2023., 2023
Selection of a suitable lipase provides for quantitative hydrolysis of triacylglycerides without unwanted coproducts. Optimization of the reaction in solely water as sole reaction medium allows for cost efficient conversion of plant oils and and recovery of a highly pure glycerol product as precursor for acrylonitrile synthesis as well as free fatty ...

Modeling the rheological properties of plant‐based foods: Soft matter physics principles

Sustainable Food Proteins, Volume 1, Issue 3, Page 101-132, September 2023., 2023
Next‐generation plant‐based foods are colloidal systems consisting of polymers and particles whose properties can be understood using soft matter physics. Abstract There is growing interest in the design and fabrication of next‐generation plant‐based (NG‐PB) foods that have physicochemical and functional properties that simulate those of traditional ...
