Sorption is often carried out in stirred batch reactors without any consideration of how much mixing sufficient to avoid the effect diffusion compromising yield and cost due overmixing. Therefore, focus this work was study maximum sorption capacity, removal efficiency, kinetics power consumption (P) studied process are affected by different speeds, i.e., impeller speed/minimum speed for complet...

Trigonal-blpyramldal azasilatranes of the type ZSi(NHCH2CH2hN (Z = H, Me, OEt) sotvolyze In MeOH 10 give N(CH2CH2NH2h (Iren) and ZSI(OMeh. Whereas in· lermediates In this reaction are not detected, ZSi[N. (SiR3)CH2CH2laN species afford delectable intermediates of the type ZSI[N(SIR3)CHtCH2]" (NHCH2CH2b..,, N (n = 1. 2) before complete conversion 10 Iren and ZSI(OMe)3 occurs. In cases where ster...

Due to the neurotoxicity of organophosphate (OP) pesticides and nerve agents synthesized as military or terror agents, their safe destruction and disposal is of considerable current importance. A representative OP, trimethyl phosphate (TMP), was adsorbed onto NaX zeolite, two mesoporous modifications, and a low-silica X zeolite. The nucleophilic chemical reactions of TMP with the zeolites were ...

The zeolite's textural properties have a significant effect on effectiveness in the different industrial processes. This research aimed to study textual of NaX and FeX zeolites using nitrogen adsorption-desorption technique at constant low temperature. According International Union Pure Applied Chemistry, isotherm showed that studied materials were mixed kinds I/II isotherms H3 type hysteresis....

A new one-pot electrophilic chlorination and bromination with oxidative demethylation uses harmless inexpensive sodium chloride bromide Oxone to yield alicyclic ring-fused bis-benzimidazolequinones.
