Butyl stearate as a phase change material was microencapsulated within melamine-formaldehyde resin using emulsion polymerization. Morphology and thermal specification of produced microcapsules were studied by Fourier transform infrared spectroscopy, FT-IR, scanning electron microscopy, SEM, and Differential scanning calorimetry analysis, DSC. FT-IR spectra validated the existence of the butyl s...

Abstract This article presents the experimental charging and discharging characteristics of two organic phase change materials (PCMs) for application cold thermal energy storage. Lauryl alcohol butyl stearate were encapsulated in rectangular encapsulation study was carried out vapor compression refrigeration system. The experiment also conducted different masses PCMs result showed that lauryl s...

pure barium zirconate nanopowders were successfully prepared in wet-chemistry synthesismethod, using barium stearate and tetra-n-butyl zirconate as ba, zr sources and stearic acid ascomplexing reagent. the gel was calcined at 800 and 900 °c in air. results of thermal analysisare given, including both dtg and tg. fourier transform infrared spectrometry (ftir), x-raydiffraction (xrd), transmissio...

The rate of evaporation of drops of dibutyl phthalate and butyl stearate of radius approx. 0*5 mm. has been studied by means of a microbalance over a range of atmospheric pressures down to approx. 0*1 mm. of mercury. Wide departures from Langm uir’s evaporation formula were found to oceur a t these low pressures, bu t results are in good acoordance with the theory of droplet evaporation advance...
