General description

Tri(propylene glycol) methyl ether is a promising oxygenating agent for diesel fuels.[1] Bubble coalescence and post-rupture oscillation in tri(propylene glycol) methyl ether solutions using high-speed cinematography was studied.[2]

Application


  • Composition-explicit distillation curves of diesel fuel with glycol ether and glycol ester oxygenates: fuel analysis metrology to enable decreased particulate emissions.: This study by Smith, Ott, and Bruno explores the application of glycol ethers, including tri(propylene glycol) methyl ether, in diesel fuels. The research demonstrates how these oxygenates can decrease particulate emissions, providing a valuable insight into the environmental benefits and performance improvements of glycol ethers in fuel formulations (Smith et al., 2008).

Most processes involving bubbling in a liquid require small bubbles to maximise mass/energy transfer. A common method to prevent bubbles from coalescing is by the addition of surfactants. In order to get an insight into the coalescence process, capillary bubbles

We recently introduced several important improvements in the measurement of distillation curves of complex fluids. The modifications to the classical measurement provide for (1) a composition-explicit data channel for each distillate fraction (for both qualitative and quantitative analysis), (2) temperature
