Proflavine sulphate dye is acknowledged as a hazardous substance detrimental to both human health and the environment. Consequently, our primary objective was put forth straightforward, effective, economical method for purifying water contaminated with proflavine dye. The efficacy of tea-bag tissue (TBT) that utilizes membrane made cellulosic material has been evaluated its potential an adsorbent remove from water. This assessment conducted using pH 8 batch equilibrium approach. adsorption...
The following organic and organic–inorganic hybrid compounds were prepared as photo-luminescent materials efficient practical synthetic methods: 1,3-bis[4-(n-alkoxy)phenyl]-2-propen-1-one (where, n-alkoxy: O(CH2)nH, n = 6,7,8,9 or 10); 3,5-bis[4-(n-alkoxy)phenyl]-1H-pyrazole 10) (in case of 7, a mixture 3,5-bis(4-heptyloxyphenyl)-1H-pyrazole 3,5-bis(4-heptyloxyphenyl)-4H-pyrazole was detected) bis(3,5-bis [4-(n-alkoxy) phenyl]-1H-pyrazole) silver(I) nitrate 10). have been characterised their...
Continuation with our previous investigation which refers to the synthesis of a series hydrophobic symmetrical azine compounds: 1,2-bis[4-(n-alkoxy)benzylidene]hydrazine (where, n-alkoxy: O(CH2)nH, n = 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, 16 or 18), asymmetrical [1-(4-propyloxy)-2-(4ʹ-(n-alkoxy))benzylidene]hydrazine 18) was synthesised following an efficient and practical method. These compounds were by condensation reaction hydrazine hydrate 4-propyloxybenzaldehyde appropriately...
Abstract Unique properties of the two giant wheel‐shaped molybdenum‐oxides type {Mo 154 }≡[{Mo 2 }{Mo 8 1 }] 14 ( ) and 176 16 that have same building blocks either or times, respectively, are considered show a “chemical adaptability” as new phenomenon regarding integration large number appropriate cations anions, for example, in form “salt‐like” {M(SO 4 )} rings (M=K + , NH ), while resulting 146 (K(SO )) } 3 (NH (SO hybrid compounds shape parent ring structures. The chemical adaptability,...
The reactions of cyclohexane-1,2-bis(4-methyl-3-thiosemicarbazone) (CHMTSC) with MCl2 (M = Co, Ni, Cu or Zn) and Cd(NO3)2 have been shown to produce complexes in which the thiosemicarbazone has doubly deprotonated {[M(CHMTSC − 2H+)] Ni Ni)}, analogous those reported earlier other Schiff base thiosemicarbazones. However, ZnCl2 Cd(NO3)2, isolated are [ZnCl(CHMTSC)]Cl [Cd(NO3)(CHMTSC)]NO3, containing protonated forms ligand, characterised by X-ray crystallography, as free CHMTSC. kinetics...
A series of hydrophobic symmetrical azines: 1,2-bis[4-(n-alkoxy)benzylidene]hydrazine (where, n-alkoxy: O(CH2)nH, n = 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, 16, or 18) have been prepared following an efficient and practical method.
