In this study, we efficiently synthesized N-benzyl-N-methyl-dodecan-1-amine (BMDA) by the reductive amination method. We evaluated the potential anticancer...

A simple and efficient protocol for the synthesis of dibenzyl carbonates has been developed. The reaction was accomplished using benzyl halides and Cs2CO3 as the starting materials in the presence of atmospheric pressure of CO2, affording a variety of the dibenzyl carbonates in good to excellent...

Vapor liquid equilibrium (VLE) data of CO2 solubility in aqueous amine solutions are essential for solving problems associated with flue gas purification. This work presents new VLE data of 3-amino-1-propanol, 4-amino-1-butanol and 5-amino-1-pentanol, respectively. An equilibrium cell, connected...

The crystal and molecular structure of a 2:1 adduct of 1,8-bis(dimethylamino)naphthalene (proton sponge—DMAN) with 1,5-bis(p-toluenesulphonamido)-2,4,6,8-tetranitronaphthalene is determined. The NHN+ hydrogen bond in the DMAN·H+ cation is asymmetrical of 2.604(3) Å belonging to medium long bri...

The reaction of the cyclic amines 1,5-diazobicyclo[4.3.0]non-5-ene (DBN), 1,8-diazobicyclo[5.4.0]undec-7-ene (DBU) and 1,8-bis(dimethylamino)naphthalene (PS) with B(OH)3 in a 1:5 ratio affords in high yields the non-metal cation pentaborate salts [HDBN][B5O6(OH)4] (1), [HDBU][B5O6(OH)4] (2) and ...

The dioximes of 1,3- and 1,4-diacetylbenzene readily undergo regioselective double cyclopalladation on reaction with lithium tetrachloropalladate. 1,5-Bis(dimethylamino)naphthalene has been singly and doubly cyclopalladated; attempts to prepare heterodicyclometallated derivatives of this ligand ...

The thermolysis of a bis(pentacoordinate) silicon compound having two pentacoordinate silicon units at the 4- and 8-positions on the 1,5-bis(dimethylamino)naphthalene ring in the presence of diphenylacetylene affords a 1,6-dihydro-1,6-disilapyrene derivative. This reaction might proceed through ...

A fixed bed electrochemical reactor comprising stainless steel cathode/granular activated carbon (GAC) bed//Carbon anode//GAC bed//stainless steel cathode configuration was fabricated and tested for degradation of Reactive Blue 4 aqueous solutions (RB4). On the basis of measured concentrations o...

Decolorization of anthraquinone dye Reactive Blue 4 (RB4) in an aqueous solution was investigated by using Fe–ball clay (Fe–BC) as heterogeneous catalyst. The best reacting conditions were found to be 0.80 wt.% of iron ions loading on ball clay (BC) when the dosage of catalyst is 5.0 g L−1 wit...

The adsorption behavior of chitosan (CS) beads modified with 3-aminopropyl triethoxysilane (APTES) for the removal of reactive blue 4 (RB4) in batch studies has been investigated. The effects of modification conditions, such as the APTES concentration, temperature and reaction time on RB4 remova...

Catalytic reduction of 4-nitrophenol (4-NP) represents a useful method of converting 4-NP into a more environmentally friendly product, 4-aminophenol (4-AP). Prussian blue (PB) (Fe3[Fe(CN)6]2) and its Prussian blue Analogues (PBAs) (MII[Fe(CN)6] PBAs (MII = Mn, Co, Ni, and Zn) exhibit hierarchic...

The adsorption of dye on chitosan and its derivatives is considered as an alternative and environmentally friendly method. Nevertheless, chemical modification of chitosan can lead to a more suitable adsorbent. In this study, the adsorption performance of chemically modified chitosan beads using ...

In this study inedited polymetallic nanoparticles were synthesized from electronic wastes of spent lithium-ion batteries (PN-LIB) and applied in the removal of the dye reactive blue 4 (RB4). Initially, the extraction of metals from batteries was performed using HCl/HNO3 (3:1 v/v). Subsequently, ...

In the present study novel polypyrrole-cellulose-graphene oxide nanocomposite (PCeGONC) was employed for the immobilization of ginger peroxidase (GP) via simple adsorption mechanism. Immobilization of enzyme on the obtained support resulted in enhancement of the enzyme activity. The recovery of ...

Brazil is the fifth biggest global manufacturer of textiles and the fourth in cotton textile exports. Textile effluents contain organic dyes that are highly recalcitrant and difficult to oxidize by conventional physico-chemical and biological treatments. Mid-sized textile factories require relia...

Adsorption performance of chitosan (CS) hydrogel beads was investigated after impregnation of CS with hexadecylamine (HDA) as a cationic surfactant, for the elimination of reactive blue 4 (RB4) from wastewater. The CS/HDA beads formed with 3.8% HDA were the most effective adsorbent. The adsorpti...
