متن کاملBehaviour of Solutions of Tetraalkylammonium Salts in Ethyl Bromide as Liquid Membranes
Preliminary resu lts1 showed that solutions of tetraheptylammonium bromide in ethyl bromide (EtBr) behave as quasi-ideal anionic membranes with respect to the Br~ ion. It is the aim of the pre sent work to give a picture of the properties of EtBrbased liquid membranes. The physico-chemical requirements to be satisfied by the system, solvent + salt, of which a liquid membrane consists, are: (i)...
متن کاملRegioselective conversion of epoxides to vicinal nitrohydrins catalyzed by silica-bound 3-{2-[poly(ethylene glycol)]ethyl}-substituted 1-methyl-1H-imidazol-3-ium bromide as a green and reusable catalyst under aqueous thermal conditions
An environmentally benign procedure for the synthesis of vicinal nitrohydrins via the regioselective ring opening reaction of epoxides with nitrite anion using silica-bound 3-{2-[poly(ethylene glycol)]ethyl}-substituted 1-methyl-1H-imidazol-3-ium bromide as an effective heterogeneous phase transfer catalyst was described. Short reaction time, high yield of products, simple work-up proc...

متن کاملPotassium carbonate as a base for cycloalkylation of diethyl malonate and ethyl cyanoacetate in solid-liquid two phase systems
The cycloalkylation of diethyl malonate and ethyl cyanoacetate with alkyl dihalide was investigated by using comminuted potassium carbonate as a base and toluene as a solvent in the presence of hexadecyltrimethylammonium bromide (HTMAB) as a phase-transfer catalyst, which provided a conventional procedure with the advantage of short reaction period and high product yield. The factors influencin...
