چکیده

Abstract The heat capacity of different mixtures terpenes (α-pinene, β-pinene, limonene oxide) and solvents (acetone, toluene, ethyl acetate) at atmospheric pressure (85.1 kPa atm in Medellin, Colombia) were measured using a microcalorimeter several terpene molar fractions from room temperature to value close the solvent boiling point. analyzed acetone + α-pinene 298.15 323.15 K, toluene oxide β-pinene 358.15 acetate between 338.15 K. These mixtures, selected ranges, are used fine chemical catalytic reactions. experimental values fitted polynomials as function temperature. Excess was calculated with for all it decreased Experimental uncertainty less than 1.5% confidence level 95% k = 2. results consistent, example mixture increased composition solvent; 308.15 K 252.73 245.17 J mol −1 when 0.1546 0.2797 0.1546, 237.26 J·mol ·K − 1

Dielectric Dispersion in 1,2-diaminopropane– Dimethylaminoethanol Mixtures as a Function of Composition and Temperature

The dielectric dispersion ε' and dielectric loss ε" of binary mixture of 1,2-diaminopropane–dimethylaminoethanol were measured by employing the time domain reflectometry technique over a frequency range from 10 MHz to 20 GHz at 288, 298, 308, and 318 K temperatures. The accuracy in the measurement of the ε' and ε" values obtained from this technique is within ±5%. To evaluate various dielectric...

Determination of the Heat Storage Capacity of Pcm and Pcm-objects as a Function of Temperature

Phase change materials (PCM) are thermal storage materials with a high storage density for small temperature range applications. One such application is the storage of natural cold of the night to use during daytime, called “free cooling”. Very high energy efficiency can be reached as the cold has not to be generated. Those systems are especially interesting for lightweight buildings, which hea...
