Towards cleaner PolarClean: Efficient synthesis and extended applications of the polar aprotic solvent methyl 5-(dimethylamino)-2-methyl-5-oxopentanoate

As a result of recent efforts in green solvent selection, methyl 5-(dimethylamino)-2-methyl-5-oxopentanoate, sold under the brand name Rhodiasolv PolarClean, has received considerable scientific and industrial attention as a possible non-toxic replacement

Hydroxybenzophenone-based stabilizers and polymers end-capped with the same

The invention relates to hydroxybenzophenone-based compounds of formula (I) that are used to improve UV, thermal, and thereto-oxidative stability of high performance aromatic polymers in a blend or as end-cappers of the same polymers.

AROMATIC SULFONIC ACID DERIVATIVE, SULFONIC ACID GROUP-CONTAINING POLYMER, BLOCK CO-POLYMER, POLYMER ELECTROLYTE MATERIAL, POLYMER ELECTROLYTE MOLDED BODY, AND SOLID POLYMER FUEL CELL

Provided are an aromatic sulfonic acid derivative and a sulfonic acid group-containing polymer, each of which has excellent proton conductivity even under low humidification conditions, while having excellent mechanical strength and chemical stability, and enables a solid polymer fuel cell to achieve high output and excellent physical durability when used therein. This aromatic sulfonic acid derivative has a specific structure and is characterized in that a sulfonic acid group is introduced into more than 50% of all the phenyl groups. This sulfonic acid group-containing polymer is characterized by being obtained by polymerization using the aromatic sulfonic acid derivative, and is also characterized by having a specific structure.

N-ALKYL-4-(N',N'-DIALKYLAMINO)PYRIDINIUM SALTS: THERMALLY STABLE PHASE TRANSFER CATALYSTS FOR NUCLEOPHILIC AROMATIC DISPLACEMENT

N-Alkyl salts of 4-dialkylaminopyridines are effective phase transfer catalysts which are up to 100 times more stable than tetrabutylammonium bromide to conditions encountered in nucleophilic aromatic substitution reactions.These salts are thermally stable to over 300 deg C, and promote reactions in non-polar solvents (or in the absence of solvent) at temperatures as high as 200 deg C.
