Abstract

The invention provides a novel hydrocarbon-containing carboxylic acid, hydrocarbon-containing sulfonic acid, hydrocarbon-containing sulfuric acid ester, or a salt thereof, and a surfactant. Each of them is a compound represented by the following formula (1):

CR 1 R 2 R 4 —CR 3 R 5 —X-A

wherein R 1 to R 5 are each H or a monovalent substituent; at least one of R 1 or R 3 is a group represented by the formula: —Y—R 6 ; at least one of R 2 or R 5 is a group represented by the formula: —X-A or a group represented by the formula: —Y—R 6 ; and As at the respective appearances are the same as or different from each other, and are each —COOM, —SO 3 M, or —OSO 3 M.

First claim

The invention claimed is:

1. A compound represented by the following formula (1):

wherein R 1 to R 5 are each H or a monovalent substituent; at least one of R 1 or R 3 is a group represented by the formula: —Y—R 6 ; and at least one of R 2 or R 5 is a group represented by the formula: —X-A or a group represented by the formula: —Y—R 6 ;
Xs at the respective appearances are the same as or different from each other, and are each a divalent linking group or a direct bond;
As at the respective appearances are the same as or different from each other, and are each —COOM, —SO 3 M, or —OSO 3 M, wherein M is H, a metal atom, NR 7 4 , imidazolium optionally containing a substituent, pyridinium optionally containing a substituent, or phosphonium optionally containing a substituent, wherein R 7 is H or an organic group;
R 6 s at the respective appearances are the same as or different from each other, and are each
a group represented by the formula: —R 10 —CO—R 11 ,
a group represented by the formula: —R 10 —C(═O)O—R 11 ,
a group represented by the formula: —R 11 , or
a group represented by the formula: —R 10 —NR 8 CO—R 11 ,

wherein R 8 is H or an organic group; R 10 is an alkylene group; and R 11 is an alkyl group optionally containing a substituent;
the group represented by the formula: —Y—R 6 is
a group represented by the formula: —R 10 —CO—R 11 where Y is a direct bond,
a group represented by the formula: —OC(═O)—R 10 —CO—R 11 where Y is —OC(═O)—,
a group represented by the formula: —C(═O)O—R 10 —CO—R 11 where Y is —C(═O)O—,
a group represented by the formula: —OC(═O)—R 10 —C(═O)O—R 11 where Y is —OC(═O)—,
a group represented by the formula: —C(═O)O—R 11 where Y is —C(═O)O—,
a group represented by the formula: —NR 8 CO—R 10 —CO—R 11 where Y is —CONR 8 —, or
a group represented by the formula: —CONR 8 —R 10 —NR 8 CO—R 11 where Y is —NR 8 CO—,

wherein R 8 is H or an organic group, R 10 is an alkylene group, and R 11 is an alkyl group optionally containing a substituent, and when two or more of the groups represented by the formula: —Y—R 6 are present, the groups at the respective appearances are the same as or different from each other;
R 4 and R 5 are each H or a C1-C4 alkyl group;
any two of R 1 to R 5 optionally bind to each other to form a ring;
when R 6 contains none of a carbonyl group, an ester group, and an amide group, X is a divalent linking group containing at least one selected from the group consisting of a carbonyl group, an ester group, an amide group, and a sulfonyl group.

2. The compound according to claim 1 ,
wherein the compound is a compound represented by the following formula (1-1):

wherein R 3 to R 6 , X, A, Y, and —Y—R 6 are defined as mentioned above, or a compound represented by the following formula (1-2):

wherein R 4 to R 6 , X, A, Y, and —Y—R 6 are defined as mentioned above.

3. The compound according to claim 1 ,
wherein M is H, Na, K, Li, or NH 4 .

4. The compound according to claim 1 ,
wherein M is Na, K, or NH 4 .
