Ligand-free Guerbet-Type Reactions in Air Catalyzed by In-Situ Formed Complexes of Base Metal Salt Cobaltous Chloride

Inexpensive, earth-abundant and environmentally benign cobaltous chloride efficiently accomplishes the catalytic β-alkylation of alcohols in air at 140 °C. At higher loadings of cobaltous chloride (1 mol%) in the presence...

Poly(arylene ether)s with aromatic azo-coupled cobalt phthalocyanines in the side chain: synthesis, characterization and nonlinear optical and optical limiting properties

A novel poly(arylene ether) with azo-coupled cobalt phthalocyanine in the side chain was prepared by 1,2-benzodinitrile, anhydrous cobaltous chloride and a novel azobenzene-containing poly(aryl ether).

Structure and Properties of Cobaltous Chloride/Polyvinyl Alcohol-Glutaraldehyde(CC/PVA-GA) Reversible Thermochromic Microcapsule

The low-temperature reversible thermochromic microcapsules was prepared by interfacial polymerization, which an aqueous phase containing CoCl2 was used as the internal water phase (W1), cyclohexane was used as the oil phase (O), polyvinyl alcohol was used as the external water phase (W2) to form the uniform W1/O/W2 multiple emulsion. The structures of microcapsules were investigated using infrared spectrum (IR), electron microscopy (SEM) and polarization microscope. The properties of microcapsules, such as thermochromism and solvent resistance were also investigated. The results presented that the particle size of capsules was uniform, their walls were transparency, and the microcapsules were provided with excellent sensitivity to heat, reversibility and solvent resistance.
