The extraction of lactic acid(HA) with primary amine N1923(RNH 2) has been studied by means of a slope method and IR spectrophotometry at (298±1) K. The composition of the extracted complex was found to be RNH 2HA. The equilibrium constant of extraction was determined as lg K ex = 1 63. The results showed that lower temperature was favorable for the extraction.
The crystallite and thin film of (Zn,Hg)S at different solvents were prepared by thermolysis of thiocyanoto complexes. The samples were characterized by X ray diffraction (XRD), transmission electron microscopy (TEM) and scanning electron microscopy (SEM). The results of these studies show that the properties of solvents are important in controlling the sizes and shapes of the final products.
