Research on the manufacturing of experimental biodegradable films (EBF) was carried out in the laboratory. Recipes containing 8, 10, and 15% of corn and potato starch were analyzed. It was found that the EBF based on potato starch with a 10% concentration is more plastic and retains its shape well compared to other samples.
The vegetative part of the rice plant, Oryza sativa L., that remains after paddy fields have been cleared during harvest or afterward is known as rice stubble. Carboxymethyl Cellulose from Rice Stubble (CMCr) is a promising biopolymer source that can be made from rice stubble waste. Carboxymethyl cellulose was synthesized from rice stubble by a solvent-casting method. Various types of plasticizers (glycerol and olive oil) and the components they contain provide flexibility for use as a material for food packaging.
The structure and properties of modified poly(lactiс acid) films suitable for use as packaging materials and paper lamination were studied. Modification of poly(lactiс acid) of different degrees of crystallinity with glycerol was performed.
Alkaline transesterification of sunflower oil by n-butanol and ethanol on alkoxide-containing dried solutions of potassium hydroxide has been carried out. Complex character of spontaneous dividing of butanolysis products, accompanying with formation of three different species of glycerol layers, was observed. One of the later was found to be high-alkaline pure glycerol.
The assumption that oxides (glycidol, glycidol acetate, glycidol formate) are the intermediate molecular products of the oxidation reaction of allyl alcohol and its esters in the medium of acetic acid has been grounded. To optimize the process of obtaining glycerin esters the kinetics of these oxides reaction with acetic and formic acids has been investigated. Glycidol formate was found to be the most stable compound and glycidol – the least stable one. The rate of oxides reaction with formic acid is by order higher than that with acetic acid.
