In the last decade, attention to the synthesis of plant-based monomers has been grown, due to their biocompatibility, non-toxicity, also their renewal. Polymers based on them can be used as an alternative to conventional polymers of petrochemical origin, to produce composites, coatings and other materials especially those that are used to decorate the interiors of houses and offices. There is a growing interest in plant oil-based monomers. A range of the hydrophobic monomers that are used to obtain paints, adhesives, plasticizers, coatings etc. were synthesized.
The aim of this study was to obtain and characterize starch fatty esters with variations in the hydrophilic/lipophilic balance and to assess whether these samples have potential application in oil-based drilling fluids. The variation in the hydrophobicity of the samples was verified by means of viscosity tests, which suggested that the products had varied solubility parameters, near the value of the solvent n-paraffin.
Power-ecological characteristics of diesel engine work on ethyl esters of rapeseed and sunflower oils and their blends with mineral diesel have been studied. Acceptable power and high environmental performance of the engine work on the studied fuels have been established. It is shown that fuels on the basis of sunflower oil are slightly inferior to fuel on the basis of rapeseed oil in energy performance but surpasses them in environmental performance.
