“…The individ uality and purity of the compound were confirmed via TLC on silufol, elemental analysis, spectrophotome try and 1 H NMR spectroscopy (Bruker 500). The heat effects of dissolution were measured on an isoperibol calorimeter with computer data recording and processing [7,8]. The precision with which the temperature of the thermostatting medium Termostat A3 (BMTs Minsk) was maintained was ±0.001 K. The sensitivity of the temperature measurement circuit of the reference calorimeter (BMTs, Minsk) was 0.00001 K. HPTME is low soluble in DMF and especially in octanol 1; correct determination of heat effects of dis solution of porphyrin is therefore a difficult problem.…”

Heat effects of the dissolution of hematoporphyrin tetramethyl ether are measured on a variable temperature calorimeter for the first time in N,N dimethylformamide and octanol 1 in the temperature range of 298 to 318 K. Standard enthalpies and heat capacities of dissolution of bioligand are calculated and compared to data obtained earlier for deuteroporphyrin dimethyl ether and ethyl acetate. Partial molar heat capacities of hematoporhyrin are determined at infinite dilution using data from differential scanning calo rimetry.

The enthalpies of mixing of water (H 2 O) + sodium dodecyl sulfate (NaDDS) + 1-pentanol (PeOH) + triethanolamine (TEA) mixtures with different compositions at 298.15 K are determined using the thermochemical cycle. The enthalpies of dissolution of NaDDS, H 2 O, PeOH, TEA, and H 2 O + TEA + PeOH + NaDDS mixtures in 2-propanol are measured by means of calorimetry. The formation of the studied mixtures from neat components is shown to be mainly an exothermic process. The influence of the nature of components and a mixture's composition on the enthalpies of mixing is discussed.

The enthalpies of solution of ethylacetate (EtOAc) in water, octane and 1-octanol (OctOH) were measured at 298, 308 and 318 K using a precise isoperibol calorimeter. The standard enthalpies and heat capacities of these non-electrolyte solution were computed and compared with the previously obtained sol H • and C • p values in N,N-dimethylformamide (DMF). Partial molal heat capacities of EtOAc in water and in organic solvents were calculated and compared with the available literature values.
