Izuchena termodinamika processa rastvoreniya butadiena-1,3 v vodno-ammiachnyh rastvorah nitrata kaliya v intervale temperatur 20-80 °S. Na osnovanii poluchennyh dannyh bylo ustanovleno, chto rastvorimost' butadiena-1,3 v vodno-ammiachnyh rastvorah podchinyaetsya zakonu Genri. Pokazano, chto nitrat kaliya okazyvaet vysalivayuschee deystvie na rastvorimost' butadiena-1,3, kotoryy umen'shaetsya s povysheniem temperatury. Dobavlenie ammiaka k vode i vodnym rastvoram nitrata kaliya uvelichivaet rastvorimost' butadiena-1,3. Opredeleny termodinamicheskie funkcii processa rastvoreniya butadiena-1,3 i termodinamicheskie harakteristiki gidratirovannogo uglevodoroda v vodno-ammiachnyh rastvorah nitrata kaliya. Uvelichenie teploty rastvoreniya butadiena-1,3 v vodno-ammiachnom rastvore nitrata kaliya podtverzhdaet predpolozhenie ob obrazovanii vodorodnoy svyazi mezhdu atomami vodoroda molekuly ammiaka i π-elektronami butadiena-1,3. Sravnenie chislennyh znacheniy termodinamicheskih funkciy processa rastvoreniya butadiena-1,3 i 2-metilpropena pokazalo, chto s uvelicheniem stepeni nenasyschennosti molekuly uvelichivaetsya kak izmenenie ental'pii, tak i izmenenie entropii.
