TL;DR: In this paper, the performance of a trickle-bed air biofilter (TBAB) treating isopropyl alcohol (IPA) and acetone (ACE) mixtures was investigated under different gas flow rates and influent concentrations.
47 citations
TL;DR: In this article, advanced oxidation processes (AOPs) have been successfully used to decompose isopropyl alcohol (IPA) and its major degradation intermediate, acetone formation and total organic carbon (TOC) removal efficiency were studied using O3, O3/UV, H2O2/UV.

TL;DR: In this paper, the authors used the three point bending method and the variation of stress with the immersion time at constant strain to evaluate the chemical attack of amorphous polycarbonate in isopropyl alcohol, ethylene glycol monomethyl ether and methanol.

TL;DR: In this paper, a process design for the continuous recovery of lactic acid from fermentation broth by reactive distillation (esterification and hydrolysis with C 1 to C 4 alcohols) is developed and optimized to minimize cost.
Abstract: Process designs for the continuous recovery of lactic acid from fermentation broth by reactive distillation (esterification and hydrolysis with C1 to C4 alcohols) are developed and optimized to minimize cost. The best designs are qualitatively different for different alcohols because of the differing volatility ranking of reactants and products and the formation of a two-liquid phase zone in some cases. The results suggest that the methanol and butanol processes are the most attractive. The costs of these two processes are similar, and the ranking depends on the payback period. The ethanol and isopropyl alcohol processes are more expensive because an entrainer is required to break the alcohol/water azeotrope.

TL;DR: In this article, reduced pressure etching of thermal oxide in anhydrous HF gas with three different alcoholic solvent vapors is studied. And the etch rates are interpreted in terms of alcohol vapor pressure, HF ionization, and reaction product desorption.
Abstract: Reduced pressure etching of thermal oxide in anhydrous HF gas with three different alcoholic solvent vapors is studied. Thermal oxide etch rates as functions of temperature, pressure, time, and HF partial pressure are presented for methanol, ethanol-water azeotrope (95.6% ethanol, 4.4% water), and 2-propanol (isopropyl alcohol). The etch rates are interpreted in terms of alcohol vapor pressure, HF ionization, and reaction product desorption. The efficient desorption of reaction products compared to vapor HF/H 2 O is believed to be responsible for both the wider process window for alcoholic solvents and the alleviation of the solid residue formation problem. Among the alcoholic solvents studied, methanol has the best potential while 2-propanol can also be useful in selected applications
