The effect of magnetic field on the liquid-liquid equilibrium of two ternary systems (water + acetic acid + butyl acetate and water + acetic acid + dimethyl succinate) at 298.15 K under atmospheric pressure was investigated. The results obtained show that the strength of the magnetic field (0.02 T) affects the solubility of acetic acid in the used organic solvents. Distribution coefficients and...

In this research, the effects of important parameters, including the molar ratio of acetic acid to sulfur(S) , sonication time, temperature, and hydrogen the molar ratio of peroxide to sulfur on the performance of ultrasound-assisted oxidative desulfurization were studied using the response surface method (RSM). To this end, a model fuel containing n-decane and dibenzothiophene at a concentrati...

Microbial cell factories with the ability to maintain high productivity in the presence of weak organic acids, such as acetic acid, are required in many industrial processes. For example, fermentation media derived from lignocellulosic biomass are rich in acetic acid and other weak acids. The rate of diffusional entry of acetic acid is one parameter determining the ability of microorganisms to ...

Indole-a-acetic acid is well known as an inducer as well as an inhibitor of several growth and differentiative processes in plants, lower metazoa, and microorganisms. The principle of unity in biology suggests that these diverse effects of indole-3-acetic acid may all be consequences of interference with a common reaction or series of reactions; therefore, the study of the action of indolea-ace...

Both sexes of the noctuid moths Lacanobia subjuncta (Grote & Robinson), Mamestra configurata Walker (bertha armyworm) and Xestia c-nigrum (L.) (spotted cutworm) are attracted to the combination of acetic acid and 3-methyl-1-butanol (isoamyl alcohol). A controlled-release system for use of this attractant in traps was comprised of separate polypropylene vials for each chemical, with the chemical...

Haa1 is a transcriptional activator required for Saccharomyces cerevisiae adaptation to weak acids. Here we show that the constitutive HAA1-overexpressing strain acquired a higher level of acetic acid tolerance. Under conditions of acetic acid stress, the intracellular level of acetic acid was significantly lower in HAA1-overexpressing cells than in the wild-type cells.

Silt,?I have the honour to ask you to publish tho followingnote on the uso of acetic acid as an antidote to carbolic acid. Once when I was cleaning a wound I had to dip my hand over and over again into carbolic lotion (1 in 40), and L soon found a painful sensation in my arm from fingers to shoulder joint. I then found that I had a scratch on my finger. [ applied some acetic acid on a piece of ...

simple and corresponding impacts of adding acidic improvers (lactic acid , acetic acid and citric acid ) on bread staling has been researched twice in 3 levels( 0%, 0.25 % and 0.5 %) by factorial experimental method .there was an orthogonal comparison between the two treatments (acidified treatments and sourdough groups) in the second stage. the effect of lactic acid on bread staling was signif...

Methyl indolenines (4a-c) and(5a-c) were prepared in high yield by a Fischer indole synthesis reaction of o,m-tolylhydrazine hydrochlorides (1a-b) with isopropyl methyl ketone (2) and 2-methylcyclohexanone (3) in acetic acid at room temperature. o,p- Nitrophenylhydrazines (1c-d) were reacted with 2-methylcyclohexanone (3) in acetic acid at reflux to give nitroindolenines (5d-e), while the attem...

Polar indole-3-acetic acid movement was observed in killed plant segments and in artificial model systems. The polar diffusion of indole-3-acetic acid was observed in tissue killed by chemical or physical means in an agar-plant system and in a multicelled Plexiglas dialysis chamber containing hypocotyl tissue gradients or gradients of anion exchange material.It was suggested that polar indole-3...
