Embodiment 1

[0093] Example 1 [Synthesis of thickening stabilizer (1) (1,2,4,5-cyclohexanetetracarboxylic acid bis(2-ethylhexylamide) bis(oleamide))]

[0094] Feed pyridine 20mL, 1,2,4,5-cyclohexanetetracarboxylic acid-1 ,2: 4.5 g (0.02 mol) of 4,5-dianhydride, 10.6 g (0.04 mol) of oleylamine, the temperature in the system was set to 50° C., and aging was carried out for 3 hours.

[0095] Thereafter, 5.2 g (0.04 mol) of 2-ethylhexylamine and 5.5 g (0.044 mol) of diisopropylcarbodiimide were charged, and aging was further performed for 8 hours.

[0096] Thereafter, low boiling point components in the obtained crude liquid were removed by an evaporator, and washed with methanol to obtain a pale yellow wet powder. Further, for the obtained wet powder, utilize CHCl 3 / CH 3 OH (70 / 30 (v / v)) was recrystallized to obtain 1,2,4,5-cyclohexanetetracarboxylic acid bis(2-ethylhexylamide) bis(oleamide)[1,2, 4,5-Cyclohexanetetracarboxylic acid-1,4-bis(2-ethylhexylamide)-2,5-bis(oleamide) and 1,2,4,5...

Embodiment 2

[0098] Example 2 [Synthesis of thickening stabilizer (2) (1,2,4,5-cyclohexanetetracarboxylic acid bis(2-ethylhexylamide) bis(stearylamide))]

[0099] Feed pyridine 20mL, 1,2,4,5-cyclohexane tetracarboxylic acid-1,2:4 , 4.5 g (0.02 mol) of 5-dianhydride, 10.7 g (0.04 mol) of stearyl amine, the temperature in the system was set to 50°C, and aging was performed for 3 hours.

[0100] Thereafter, 5.2 g (0.04 mol) of 2-ethylhexylamine and 5.5 g (0.044 mol) of diisopropylcarbodiimide were charged, and aging was further performed for 8 hours.

[0101] Thereafter, low boiling point components in the obtained crude liquid were removed by an evaporator, and washed with methanol to obtain a pale yellow wet powder. Further, for the obtained wet powder, utilize CHCl 3 / CH 3 OH (70 / 30 (v / v)) was recrystallized to obtain 1,2,4,5-cyclohexanetetracarboxylic acid bis(2-ethylhexylamide) bis(stearylamide)[1, 2,4,5-Cyclohexanetetracarboxylic acid-1,4-bis(2-ethylhexylamide)-2,5-bis(stearylamide)...

Embodiment 3～4、 comparative example 2

[0108] Weigh each fluid organic substance shown in Table 1 in a test tube (liquid paraffin, isododecane, cetyl octanoate: boiling point above 100°C) each 1cm 3 10 mg of the thickening and stabilizing agent obtained in the above-mentioned Examples 1, 2 and Comparative Example 1 were respectively added and mixed, heated and stirred at 100° C. to make the fluid organic substance compatible with the thickening and stabilizing agent, and cooled to A thickened and stabilized composition was obtained at 25°C.

[0109] Measure the viscosity of the obtained thickening and stabilizing composition, confirm how many times the viscosity of various fluid organic substances is thickened, and evaluate the thickening property according to the following criteria, and compare the thickening property evaluation results of these solvents All the cases of 4 or more were evaluated as good thickening effect "◯", and the case of including 3 or less in the thickening property evaluation results of thes...

Abstract

Provided is a compound for gelling or thickening a fluid organic substance to the desired viscosity or for uniformly stabilizing a composition containing a fluid organic substance, a thickening stabilizer including the compound, a thickening stabilization composition including the thickening stabilizer and a fluid organic substance, and a method for producing the thickening stabilization composition. This compound is represented by formula (1). In the formula, R1 and R2 are mutually different and represent C4 or higher aliphatic hydrocarbon groups, and n represents an integer from 1-3. This thickening stabilizer includes the aforementioned compound.

Description

technical field [0001] The present invention relates to a novel compound having a function of thickening and stabilizing fluid organic substances such as oil, a thickening stabilizer using the compound, and a thickening and stabilizing composition containing the thickening stabilizer. This application claims priority based on Japanese Patent Application No. 2014-098783 for which it applied in Japan on May 12, 2014, and uses the content here. Background technique [0002] The method of thickening and stabilizing a liquid is a very important technology in industry. For example, mayonnaise, salad dressing, etc., which are metastable emulsions, can maintain their emulsified state stably for a long time because the water-based component has increased. Thick stabilization. Therefore, various thickening stabilizers have been developed. [0003] As a compound which thickens and stabilizes an aqueous medium, the alkyl acrylate copolymer etc. are known, for example. [0004] On the...
