Isobaric Vapor−Liquid Equilibria for the Systems Propionic Acid + Butyric Acid, Isobutyric Acid + Butyric Acid, Butyric Acid + Isovaleric Acid, and Butyric Acid + Hexanoic Acid at 14 kPa

Journal of Chemical & Engineering Data, 2002
Isobaric vapor-liquid equilibria were measured at 14 kPa for the binary systems propionic acid + butyric acid, isobutyric acid + butyric acid, butyric acid + isovaleric acid, and butyric acid + hexanoic acid. The experimental data were modeled using the γ-φ approach as discussed by Raal and Muhlbauer.

Butyric acid and pivaloyloxymethyl butyrate, AN-9, a novel butyric acid derivative, induce apoptosis in HL-60 cells

Journal of Cancer Research and Clinical Oncology, 1997
A novel butyric acid derivative, pivaloyloxymethyl butyrate, AN-9, was previously shown to be a potent differentiating agent. AN-9 exerts a significant anticancer activity in vitro and in vivo. In all the activities examined, AN-9 was more potent than butyric acid. Here we show that AN-9 and butyric acid induce cell death by apoptosis.

Metabolic engineering of Clostridium acetobutylicum for butyric acid production with high butyric acid selectivity

Metabolic Engineering, 2014
A typical characteristic of the butyric acid-producing Clostridium is coproduction of both butyric and acetic acids. Increasing the butyric acid selectivity important for economical butyric acid production has been rather difficult in clostridia due to their complex metabolic pathways.

Vapour–liquid equilibrium of carboxylic acid–alcohol binary systems: 2-Propanol+butyric acid, 2-butanol+butyric acid and 2-methyl-1-propanol+butyric acid

Fluid Phase Equilibria, 2014
Abstract Isothermal vapour–liquid equilibrium (VLE) data were measured for alcohol–carboxylic acid systems using a dynamic recirculating apparatus operated isothermally. For super-atmospheric pressures, a stainless steel version of the apparatus was used with sight glasses in the Cottrell pump and liquid and condensate sampling chambers to observe ...

ULTRASONIC ABSORPTION IN BUTYRIC ACID

Canadian Journal of Chemistry, 1958
Ultrasonic absorption has been measured in pure butyric acid by a pulse technique from 0 ° to 40 °C. and values of the relaxation frequency obtained. The activation energy of the relaxation process is shown to be 1.1 kcal./mole. These results are compared with published values for acetic and propionic acids and possible relaxation processes are ...
