In a Article，once mentioned of 73464-50-3, HPLC of Formula: C13H18O10

When acetylated pyranose-1,2-(ethyl orthoacetates) were hydrolyzed in acidic solvents, the ring-opening of the orthoacetate rings was influenced by the axial or equatorial OAc group at C-4 on the pyranoses; on acid-catalyzed hydrolysis, 3,4,6-tri-O-acetyl-alpha-D-galactopyranose- (8) and methyl 3,4-di-O-acetyl-alpha-D-galacturonatopyranose-1,2-(ethyl orthoacetate) (16) having an axial OAc group at C-4 on the pyranose rings gave 1,3,4,6-tetra-O-acetyl-alpha-D-galactopyranose (9) and methyl 1,3,4-tri-O-acetyl-alpha-D-galacturonatopyranose (23), respectively, whereas 3,4,6-tri-O-acetyl-alpha-D-glucopyranose- (10) and methyl 3,4-di-O-acetyl-alpha-D-glucuronatopyranose-1,2-(ethyl orthoacetate) (22) having an equatorial OAc group at C-4 on the pyranose rings gave 2,3,4,6-tetra-O-acetyl-D-glucopyranose (11) and methyl 2,3,4-tri-O-acetyl-D-glucuronatopyranose (24), respectively. On the acid-catalyzed hydrolysis, 3,4-di-O-acetylbeta-L-arabinopyranose-1,2-(ethyl orthoacetate) (34) having an axial OAc group at C-4 on the pyranose ring gave a mixture of 1,3,4-tri-O-acetyl-beta-L- (35) and 2,3,4-tri-O-acetyl-L-arabinopyranose (36). These selectivities of ring-opening of the 1,2-(orthoacetates) were considered to have resulted from the differences of the conformers of the 1,2-(orthoacids) intermediates derived from the 1,2-(orthoacetates) and the orientation of the acetyl groups at C-4 on the pyranose rings.

In a document type is Article, introducing its new discovery.

A novel functionalized magnetic multiwalled carbon nanotube composite was prepared and utilized as a nanosorbent for separation and preconcentration of Cr(III), Cd(II), Cu(II), Pb(II), and Ni(II) ions. The synthesized nanosorbent was characterized with various techniques. The parameters influencing the preconcentration efficiency were optimized through experimental design methodology by using Box-Behnken design method. Uptake time, pH of sample, and magnetic nanosorbent amount were evaluated in the sorption step as the main affecting factors, while four variables including type, volume, concentration of the eluent, and elution time were considered in the elution step. After sorption and elution steps, the target analytes were determined by flame atomic absorption spectrometry. Limit of detection was 0.5, 0.08, 0.7, 0.4, and 0.1 ng mL?1 for Cr(III), Cu(II), Pb(II), Ni(II), and Cd(II) ions, respectively. All relative standard deviations of the method were <9.5%. The capacity of the sorbent ranged between 184 and 215 mg g?1. Finally, the developed method was successfully applied to the rapid extraction of trace amounts of these ions from black tea leaf samples and drinking water.
