Abstract
The possibility of the catalytic cyclization reaction between hydrazine hydrate and acrylic acid at room temperature on an acid catalyst based on petroleum asphaltenes was studied. The effect of sulfocationite on the possibility of obtaining the target pyrazolidine-3-one was investigated. The reaction mixtures and their bottoms are analyzed. Different oligomeric and polymeric products were identified by gas chromatography-mass spectrometry and electrospray ionization. The most probable structures of the resulting products were described.
