Kinetics of Phase-Transfer Formation of Potassium Carbazolate, Catalyzed with 18-Crown-6

Kinetics of formation of potassium carbazolate in the system liquid-solid, catalyzed with 18-crown-6, was studied. Applicability of the previously proposed macrokinetic model to this process was demonstrated.

Compounding method for N-ethyl carbazole

The invention provides a compounding method for N-ethyl carbazole and relates to N-ethyl carbazole. The method comprises the following steps: performing salt-forming reaction on carbazole and proton-removing agent in an N-methyl pyrrolidone solvent, thereby generating carbazole salt; continuing introducing acetylene and reacting, thereby acquiring N-vinyl carbazole; adding a Pd catalyst into the organic solvent of the generated N-vinyl carbazole and performing hydrogenation reaction in the additives, thereby acquiring N-ethyl carbazole. A series of special catalysts are optimized, a catalytic hydrogenation technology is adopted for effectively realizing the green synthesis of N-ethyl carbazole and three-waste emission is reduced. In a hydrogenation process, the catalyst is reusable and the cost is lowered. The quality of the N-ethyl carbazole product prepared according to the hydrogenation process is higher. The traditional alkylate reagent (diethyl sulfate, ethyl carbonate, halothane, and the like) or the toxic organic solvent is not required, no waste liquid is emitted and the compounding method is a green and clean production technology.

Regioselective ring-opening of epoxides by carbazole: A direct preparation of novel N-(β-hydroxyalkyl)carbazoles

The influence of various parameters including solvent, base and temperature on the reaction between carbazole and epoxides was studied This led to the development of a regioselective ring-opening of epoxides by the potassium salt of carbazole in DMSO at 100 °C which is a straightforward way to prepare new N-(β-hydroxyalkyl)carbazoles in good to excellent yields. Fifteen new compounds are described.

Norbornene compounds with cross-linkable groups and their derivatives

The present invention provided a norbornene compound with cross-linkable groups and their derivative polymers, wherein said cross-linkable groups were olefin or epoxy groups. Norbornene polymers with cross-linkable side chain and their block copolymers as well as modified derivatives were prepared via living ring-open metathesis polymerization method. The resulting polymers with excellent solubility and optic properties had narrow molecular weight distribution, well-controlled molecular weight, small refraction ration and high transparency. They were also suitable for preparing hybrid materials with high thermal stability and chemical resistance.
