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.
