چکیده
In this study, after specifying theoretical reaction conditions required for the chemical reaction, potassium pentaborate (KB5) was synthesized from dihydrogen phosphate ( $${\text{KH}}_{2} {\text{PO}}_{4}$$ ) solution and raw colemanite $${\text{Ca}}_{2} {\text{B}}_{6} {\text{O}}_{{11}} \cdot 5{\text{H}}_{2} {\text{O}}$$ ore. The slow evaporation method used at 25 °C. effect of time (6–18 h) on crystallization studied. Synthesized minerals were characterized by X-ray diffraction (XRD), Fourier transform infrared (FT-IR), RAMAN spectroscopy, scanning electron microscopy (SEM). results according to XRD, FT-IR, RAMAN, SEM analyses proved that product $${\text{KB}}_{5} {\text{O}}_{8} 4{\text{H}}_{2} mineral with ICSD: 96-026-1927 pdf code. As a result, cost reduced using boron ore, colemanite, KB5 obtained in shorter lower temperature.

Although several procedures have been described for the synthesis of isocitric acid, (l-4) the optically inactive product obtained may be contaminated with the diastereomeric alloisocitric acid and, if pure, contains at most only 50 per cent of the isomer of interest in biochemistry. Pucher, Abrahams, and Vickery (5) attempted to meet the need for this substance by devising a method for the iso...
