Abstract
A lubricant composition comprising following ingredients (a) and (b) is disclosed. (a) at least one compound represented by formula (1) (b) at least one compound represented by formula (2) (R—X—)m-D (1) (b) at least one compound represented by formula (2)
Claims16
A lubricant composition comprising following ingredients (a) and (b):
- (a) at least one compound represented by formula (1)
- (R—X—)m-D (1)
- where “D” represents an m-valent cyclic group capable of bonding to “m” of —X—R;
- X each independently represents a single bond or a bivalent linking group selected from the group consisting of NH, an oxygen atom, a sulfur atom, carbonyl, sulfonyl and any combinations thereof;
- R each independently represents a substituted or non-substituted alkyl group, alkenyl group, alkynyl group, aryl group or heterocyclic group, or a halogen atom, hydroxy, mercapto, cyano, sulfide, carboxy or a salt thereof, sulfo or a salt thereof, hydroxyamino, ureido or urethane;
- and m is an integer from 2 to 11;
- (b) at least one compound represented by formula (2)
- where X11, X12 and X13 each independently represent a single bond or a bivalent linking group selected from the group consisting of NRa (where Ra is a hydrogen atom or a C1-30 alkyl group), an oxygen atom, a sulfur atom, carbonyl, sulfonyl and any combinations thereof, provided that at least one of X11, X12 and X13 represents NRb (where Rb represents a C1-30 alkyl group);
- and R11, R12 and R13 each independently a substituted or non-substituted alkyl group, alkenyl group, alkynyl group, aryl group or heterocyclic group.

A method for producing a mixture of at least two kinds of compounds represented by formula (1):
- (R—X—)m-D (1)
- where “D” represents an m-valent cyclic group capable of bonding to “m” of —X—R;
- X each independently represents a single bond or a bivalent linking group selected from the group consisting of NH, an oxygen atom, a sulfur atom, carbonyl, sulfonyl and any combinations thereof;
- R each independently represents a substituted or non-substituted alkyl group, alkenyl group, alkynyl group, aryl group or heterocyclic group, or a halogen atom, hydroxy, amino, mercapto, cyano, sulfide, carboxy or a salt thereof, sulfo or a salt thereof, hydroxyamino, ureido or urethane, provided that at least one of R is a substituent containing a repeating unit of ethylene oxy or propylene oxy;
- and m is an integer from 2 to 11;
- comprising carrying out addition reaction of ethylene oxide or propylene oxide gas which has a chain length distribution, thereby to form a mixture of at least two kinds of compounds represented by formula (1), which have a substituent containing a repeating unit of ethylene oxy or propylene oxy, of which repeating numbers of the unit are different among said at least two kinds of compounds.

A method for producing a mixture of at least two kinds of compounds represented by formula (2):
- where X11, X12 and X13 each independently represent a single bond or a bivalent linking group selected from the group consisting of NRa (where Ra is a hydrogen atom or a C1-30 alkyl group), an oxygen atom, a sulfur atom, carbonyl, sulfonyl and any combinations thereof, provided that at least one of X11, X12 and X13 represents NRb (where Rb represents a C1-30 alkyl group);
- and R11, R12 and R13 each independently a substituted or non-substituted alkyl group, alkenyl group, alkynyl group, aryl group or heterocyclic group, provided that at least one of R11, R12 and R13 is a substituent containing a repeating unit of ethylene oxy or propylene oxy;
- comprising carrying out addition reaction of ethylene oxide or propylene oxide gas which has a chain length distribution, thereby to form a mixture of at least two kinds of compounds represented by formula (2), which have a substituent containing a repeating unit of ethylene oxy or propylene oxy, of which repeating numbers of the unit are different among said at least two kinds of compounds.
