Poly (m-aminophenol) (PmAP) was synthesized chemically from aqueous solutions of the monomer meta-aminophenol in the initially basic medium by using ammonium persulfate as an oxidant. The synthesized PmAP was characterized by Fourier transform infrared spectroscopic. The film of PmAP was formed by dissolving PmAP in the dimethyl sulfoxide followed by solvent removel. The morphology of the film was obeserved by laser scanning confocal microscope (LSCM) and the ethanol sensing property was studied by testing the resistance of the PmAP film when purged air and ethanol alternately.

Reaction Media

In this paper, the production of CaCO3 particles via the carbonation route in the reaction of CaCl2 and CO2, using NH3 as a promoter of CO2 absorption, was studied. The solvents used as the reaction media for CaCO3 precipitation were aqueous solutions of methanol, isopropanol and dimethyl sulfoxide (DMSO), in a concentration range of 0–20% (v/v). It was found that the presence of an organic additive influenced the precipitation rate, the content of vaterite in the obtained product, the morphology and the size of the precipitated CaCO3 particles, as well as the rate of its transformation into calcite. The presence of all added organic solvents reduced the vaterite concentration in the produced CaCO3 both at the end of the reaction and after incubation in the reaction medium for 1 h. However, the transformation of vaterite particles into calcite in the tested solutions was slower when the 4 h and 24 h procedures were compared. The interactions of solvents with calcite and vaterite were compared using HPLC tests. DMSO molecules interacted with vaterite particles the most strongly, while the interaction of isopropanol with this polymorph was the weakest. The opposite effect was observed for interactions with calcite particles, and the affinity decreased in the series: isopropanol, methanol, DMSO.
