Tetraalkylammonium Salts as Hydrogen-Bonding Catalysts.
Although the hydrogen-bonding ability of the α hydrogen atoms on tetraalkylammonium salts is often discussed with respect to phase-transfer catalysts, catalysis that utilizes the hydrogen-bond-donor properties of tetraalkylammonium salts remains unknown. Herein, we demonstrate hydrogen-bonding catalysis with newly designed tetraalkylammonium salt catalysts in Mannich-type reactions. The structu...
متن کاملAcrylate functionalized tetraalkylammonium salts with ionic liquid properties.
Acrylate functionalized ionic liquids based on tetraalkylammonium salts with terminal acrylates- and methylacrylates were synthesized. Melting points and ionic conductivity of twenty compounds in six groups were determined. Within one group the effect of three different counterions was investigated and discussed. The groups differ in cationic structure elements because of their functional group...
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 کاملThe thermal stability of oligonucleotide duplexes is sequence independent in tetraalkylammonium salt solutions: application to identifying recombinant DNA clones.
In solutions of tetraalkylammonium salts the melting temperature of oligonucleotide duplexes is independent of nucleotide sequence and thus GC content. Data quantitating the destabilizing effects of various mismatches in these solvents are also presented. The results are in accord with theories on DNA melting and establish conditions under which oligonucleotides can be used as hybridization pro...
متن کاملImprovement of Thermal Stability of BCG Vaccine
Background: Thermal stability (TS) is a part of the BCG vaccine characterization by which the consistency of process in BCG vaccine production could be confirmed. To enhance the TS of the vaccine, some prevalent stabilizers in different concentrations were added to the final formulation of BCG bulk prior to Freeze-drying process. We found a formulation more effective than the current stabilizer...
