Derivatographic analysis (TG, DTA and DTG) coupled with mass spectrometry, FTIR spectroscopy as well as water sorption experiments were used to study the thermal properties of (NH4)(32) [Mo-110(VI) Mo-28(V) O-416 H-6 (H2O)(58) (CH3COO)(6)]. approxima

Ethanol conversion on polyaniline supported H4SiW12O40 was investigated at 443 – 483 K. Catalytic activity of the samples expressed as conversion rate per 1 m2 exhibits a maximum at H4SiW12O40 content, equal to about 30 wt.%. The proposed interpret

Basing on the kinetic and sorption experiments a mechanism of catalytic formation of methyl-tert-butyl ether (MTBE) on H4SiW12O40 was proposed. A reaction intermediate, carbenium ion C4H 9 + , is forming at the catalyst surface from isobutene supplie

A polyaniline-supported dodecatungstosilicic acid H 4 SiW 12 O 40 catalyst was tested in the electrophilic addition of methanol to isobutene resulting in methyl- tert -butyl ether. The activity of the catalyst is poor after pretreatment in helium gas

The sorption of methanol by anhydrous H4SiW12O40 (HPA) was investigated using classical sorption investigations, thermometric titration, FTIR spectroscopy and DTA and TG analyses. Methanol is sorbed by the whole volume of HPA crystallites. Sorption i

The dehydration of H4SiW12 O40·15.6 H2O was studied in situ in the IR chamber. On evacuation at room temperature the departure of most loosely bonded water characterized by bands at 3550 and 1616 cm−1 was observed. In the remaining hexahydrate the
