The changes of enthalpy for the formation of hydrogen-bonded complexes of the types AHA or AHR by the interaction of acids HR or HA with bases A have been determined at 298.15 K in propylene carbonate as solvent by a calorimetric procedure. Aliphatic carboxylates, benzoates, and phenolates ...
Three types of anhydride (maleic anhydride (MA), phthalic anhydride (PA) and pyromellitic dianhydride (PMDA)) were melt blended to end-cap poly(propylene carbonate) (PPC) by reactive extrusion. The effect of anhydride types on thermal, rheological, and mechanical properties of PPC was ...
Catalyst screening for the dimethyl carbonate production reaction performing in the liquid phase was done. CaO showed best results as well as superbase MgO/Na/NaOH. PC conversion of around 70 mol.% with 99 mol.% DMC and PG selectivity was achieved. However, reaction performing in the liquid ...
