Abstract

A compound that thickens and/or gelatinizes a fluid organic substance to a desired viscosity, or uniformly stabilizes a composition containing the fluid organic substance. Also, a thickening/stabilizing agent including the compound, a thickened/stabilized composition including the thickening/stabilizing agent and a fluid organic substance, and a method for producing the composition. The compound according to the present invention is represented by Formula (1):

(R 2 —HNOC) 4-n —R 1 —(CONH—R 3 ) n   (1)

where R 1 is a group resulting from removing four hydrogen atoms from the structural formula of an aromatic hydrocarbon or cyclohexane, R 2 is, independently in each occurrence, an aliphatic hydrocarbon group containing 1 to 4 carbon atoms, R 3 is, independently in each occurrence, an aliphatic hydrocarbon group containing 6 or more carbon atoms, and n is an integer of 1 to 3.

First claim

The invention claimed is:

1. A compound represented by Formula (1):
(R 2 —HNOC) 4-n —R 1 —(CONH—R 3 ) n   (1)

wherein
R 1 is a group resulting from removing four hydrogen atoms from a structural formula of an aromatic hydrocarbon or cyclohexane;
R 2 is, independently in each occurrence, an aliphatic hydrocarbon group containing 1 to 4 carbon atoms;
R 3 is, independently in each occurrence, an aliphatic hydrocarbon group containing 6 or more carbon atoms; and
n is an integer of 1 to 3.

2. The compound according to claim 1 ,
wherein the aromatic hydrocarbon in R 1 is selected from benzene, benzophenone, biphenyl, and naphthalene.

3. The compound according to claim 1 ,
wherein R 1 is a group resulting from removing four hydrogen atoms from a structural formula of one of benzene and cyclohexane.

4. A thickening/stabilizing agent comprising
the compound according to any one of claims 1 to 3 .

5. A thickened/stabilized composition comprising:
the thickening/stabilizing agent according to claim 4 ; and
a fluid organic substance.

6. A method for producing a thickened/stabilized composition, the method comprising the step of
mutually dissolving the thickening/stabilizing agent according to claim 4 and a fluid organic substance in each other.
