The use of polyurethanes and, therefore, the quantity of its scrap are increasing. Considering the thermoset characteristic of most polyurethanes, the most circular recycling method is by means of chemical depolymerization, for which glycolysis is finding its way into the industry. The main goal of polyurethane glycolysis is to recover the polyols...

The current invention relates to long α-ω di-functional linear molecules as building blocks closing the gap between small molecules and polymers, or in a polycondensated form, in the production of oligomers and/or polymers, surfactants, lubricants, coatings, colloidal stabilizing surface chains/molecules.

The aim of this work was to obtain and evaluate the stability of new emulsion systems, in which diacylglycerols derived from enzymatic interesterification of mutton tallow with hemp oil were used as emulsifiers. In order to achieve a higher content of the polar fat fraction in the final fat blend, a different amount of water was added to the reacti...

The purpose of this study was to form new dispersion systems based on chemically interesterified waste turkey fat containing sesame oil (2:3 wt./wt.) and to evaluate effectiveness of synthetized diacylglycerols stabilizing these emulsions. Sesame oil was used to enrich and improve turkey fat’s composition with unsaturated fatty acids derived from o...

A chemical method was developed for low-temperature synthesis of DAG from MAG followed by an easy purification procedure in order to obtain high-purity DAG. Solvent-assisted and solvent-free reaction conditions were used, combined with different catalysts (sodium methoxide, p-toluenesulfonic acid, methanesulfonic acid, and sulfuric acid). All react...
