Composition useful as friction modifier
The present invention relates to the field of fuel additives for fuel compositions and more particularly to a composition that can be used as a friction modifier, and its preparation process. More particularly, the present invention concerns a composition comprising at least one fatty acid amide of diethanolamine (DEA) and at least one fatty acid ester and/or amide of DEA oligomer, and it preparation process.
Biological Buffers with Wide Buffering Ranges
Amines and amine derivatives that improve the buffering range, and/or reduce the chelation and other negative interactions of the buffer and the system to be buffered. The reaction of amines or polyamines with various molecules to form polyamines with differing pKa's will extend the buffering range, derivatives that result in polyamines that have the same pKa yields a greater buffering capacity. Derivatives that result in zwitterionic buffers improve yield by allowing a greater range of stability.

Bis(perfluoroether carboxylic acid alkyl)amino ester and method for producing the same
A bis(perfluoroether carboxylic acid alkyl)amino ester represented by the general formula: {C.sub.nF.sub.2n+1O[CF(CF.sub.3)CF.sub.2O].sub.aCF(CF.sub.3)COO(CH.sub.2).sub.b}.sub.2NR, wherein R is a hydrogen atom, an alkyl group having 1 to 12 carbon atoms, an aryl group, or an aralkyl group; preferably an alkyl group having 1 to 6 carbon atoms or an aryl group; n is an integer of 1 to 3; a is an integer of 0 to 20, preferably an integer of 1 to 6; and b is an integer of 1 to 12, preferably an integer of 1 to 4. The bis(perfluoroether carboxylic acid alkyl)amino ester having an amino group at the end of the ester group is produced by reacting a perfluoroether carboxylic acid fluoride compound of the formula: C.sub.nF.sub.2n+1O[CF(CF.sub.3)CF.sub.2O].sub.aCF(CF.sub.3)COF and a bis(hydroxyalkyl)amine compound of the formula: HO(CH.sub.2).sub.bNR(CH.sub.2).sub.bOH at a molar ratio of 2:1 in the presence of an alkali metal fluoride.
