the distribution behavior of ofloxacin enantiomers was examined in the aqueous and organic solvent of a two-phase system containing chiral selector l-tartarate. the effect of extraction equilibrium time, buffer ph, organic solvents and length of alkyl chain of l-tartarate on the partition coefficients and enantioselectivity of racemic ofloxacin were investigated, respectively. the l-tartarate f...

The activity of biocatalysts in nonaqueous solvents is related to the interaction of organic solvents with cells or enzymes. The behavior of proteins is strongly dependent on the protonation state of their ionizable groups, which ionization constants are greatly affected by the solvent. Due to the weak ionizing and dissociating powers of common organic solvents, the charge of the protein will c...

Solvents are widely used in wood conservation for either dissolving polymers for consolidation purposes or for removing dirt or foreign matter, which was applied during previous conservation. Solvents may cause temporary swelling of the wood, and when they evaporate wood returns back to its original size. They may form complexes with wood components when unlimited swelling arises as a consequen...
