Synthesis, Characterization, and Investigation of Coating Properties of Carboxymethyl Acorn Starch (CMAS)

Nurzat ŞAYKİYEVA | Mirlan MOLDOBAYEV | Kubat KEMELOV | Canıl İSKAKOVA | Mustafa DOLAZ

Kyrgyzstan is a landlocked country in Central Asia, famous for its crystal-clear lakes, majestic Tien Shan Mountains that bisect the territory of Turkistan, and magnificent natural beauty. This study aims to evaluate the fruit (acorns) of the oak trees (Quercus robur L.) grown in Bishkek, the capital city of Kyrgyzstan. For this purpose, carboxymethyl acorn starch (CMAS), which is not synthesized in literature, is first synthesized by isolating acorn starch (AS) from the acorns. The structures of CMASs are characterized by H-1(C-13)-NMR, FT-IR, XRD, and SEM techniques. The viscosities of the s ...More

The Oxidation Behavior of Potato Starch and Benzyl Alcohol via Peroxide in the Catalysis of Metal Complexes

Mustafa DOLAZ

Two new Schiff bases ligands (HL1 and HL2) and their Co2, Mn2, Fe3, Ru3, Cr3, and VO2 complexes were synthesized and characterized by FT-IR, 1H-NMR, and Mass spect. and analytical methods. A single-crystal X-ray diffraction study determined the molecular structure of HL1. The catalytic effects of metal complexes on benzyl alcohol and potato starch (PS) oxidation were compared in an H-2O-2 medium. The percent conversion of benzyl alcohol to benzaldehyde and benzoic acid was determined by Gas Chromatography. [Co(L-1)(2)], [Mn(L-1)(2)], [Co(L-2)(2)], and [Mn(L-2)(2)] showed the highest catalytic ...More
