“…Due to the presence of acid metal started to dissolute it and inhibitors used to stop the above process. Among different type of inhibitors green and low cost inhibitors get more attention than the chemical type inhibitors, [23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41] in acid medium these inhibitors adsorbed on the low carbon steel surface through chemisorptions or physiorption or both process. For the development of low cost and eco friendly inhibitors various materials used as corrosion inhibitors including green plant extracts , food additives, crop plan wastes and oral drugs , among this expired drugs used as corrosion inhibitors by using this we lower the disposal cost of expiry drugs and reduce the pollution caused by the expiry drugs.…”

Frisium anticorrosive activity in corrosive environments was investigated. The performance of the inhibitor as studied by weight loss method along with surface morphological experiments SEM and AFM. The drug showed higher anti corrosive activity 91.66 % in 500 ppm, the above results further showed the scale of inhibition is depends on the concentration of frisium by increasing the concentration the inhibition efficiency of the drug as increased as well as increasing the temperature the inhibition rate was decreased. Impedance results showed charge transfer takes place between the metal surface and acid solution and frisium performed as a mixed type of inhibitor has proven by the polarization measurements. The drug was heavily adsorbed on the low carbon steel surface and is revealed by SEM and AFM studies. By analyzing the DFT values which leads to the accumulation of a thin layer on the metal surface. IR spectral studies have also confirmed the drug's adsorption on the metal surface.

“…68 Similarly, GLA is also extensively used in the manufacture of pharmaceuticals, primarily as a component of polymers. 69 Active pharmaceutical ingredients and GLA (1 : 1 molecular ratio) can form a co-crystal with unique thermal, spectral, X-ray, and solvation properties. In addition to being chemically and physically stable under temperature stress, the co-crystal solid is non-hygroscopic.…”

“…Liquid–liquid equilibrium (LLE) and the effect of salting out on LLE for various ternary systems have attracted considerable attention. LLE − and the salt effect − are widely used due to their industrial and economic applications in chemical engineering and wastewater treatment. An important application of the salting-out phenomenon is the separation of very hydrophilic compounds such as biobased alcohols, diols, and organic acids from aqueous fermentation broths by aqueous two-phase systems, 5-hydroxymethylfurfural separation, or application of an organic extraction solvent (salt extraction).…”

Biological Buffer Effect on Liquid–Liquid Equilibria of Systems Containing n-Butanol + Methyl Isobutyl Ketone + Water

Biofuel, that is, n-butanol, production from plant-based biomass represents a renewable energy resource that can be a substitute for fossil fuel. Thus, it is important to study the separation of n-butanol from its aqueous solution to obtain a high-purity product. Liquid–liquid extraction is a beneficial process in alcohol production to recover alcohol from the aqueous medium. Liquid–liquid equilibrium (LLE) data are needed for rational design and optimal separation operation, such as biological separation and extraction processes. The objective of this study is to determine LLE data for quaternary systems of n-butanol, methyl isobutyl ketone (MIBK), water, and a biological buffer at 303.15 K and atmospheric pressure (P = 0.1 MPa). The effect of biological buffer addition into aqueous solution was also studied. Three different biological buffers, 4-(2-hydroxyethyl)-1-piperazine propanesulfonic acid (EPPS), 4-morpholinepropanesulfonic acid (MOPS), and 4-(2-hydroxyethyl)piperazine-1-ethanesulfonic acid (HEPES), were applied in this study for the comparison. The separation factor and distribution coefficient were evaluated in this study to interpret the extraction performance of n-butanol. According to the experimental results, the extraction performance was in the order of HEPES > EPPS > MOPS, describing the strength of buffering-out as well. Furthermore, it was found that the aid of a biological buffer in the LLE systems consisting of n-butanol, MIBK, and water resulted in better extraction performance than that of the LLE systems in the absence of a biological buffer. The reliability of the experimental LLE tie-line data was satisfactorily ascertained by the Hand correlation. The non-random two-liquid and universal quasi-chemical thermodynamics models correlated well the experimental LLE tie-line data with the root mean square deviation of less than 1%. The binary interaction parameters of both models were also obtained in this study.
