Problems solved by technology

However, for 12-hydroxystearic acid, the degree of gelation cannot be adjusted, it can only be induced to either completely solidify or remain liquid
That is, the present situation is that no compound that thickens fluid organic substances to a desired viscosity has been found

Embodiment 1

[0130] Example 1

[0131] Methyl behenate (20.0 g, 56.4 mmol) and ethylenediamine (16.9 g, 281 mmol) were stirred at 110° C. for 18 hours, and the reactant was washed with methanol, followed by filtration. The filtrate was subjected to solvent distillation, and the obtained residue was purified by recrystallization using hexane. N-Docosylethylenediamine was obtained as white crystals (yield 65%, 14.0 g, 36.7 mmol).

[0132] In N-dimethylformamide (40ml) solution, spent 10 minutes to add N-docosylethylenediamine (12.0g, 31.4mmol) and triethylamine (6.35g, 62.8mmol), succinic anhydride ( 3.45 g, 34.5 mmol), stirred at 100° C. for 15 minutes. After dissolving succinic anhydride, acetic anhydride (4.81 g, 47.1 mmol) was added dropwise to the crude reaction liquid over 10 minutes, followed by stirring at 100° C. for 1 hour. The reaction mixture was poured into water (200 ml), and the precipitate was filtered and washed with water. The precipitate was purified by recrystallizat...

Embodiment 2

[0139] Example 2

[0140] N-Docosylaminoethylsuccinimide was obtained by the same method as in Example 1.

[0141] The obtained N-docosylaminoethylsuccinimide (8.00 g, 17.2 mmol) and hexamethylenediamine (10.0 g, 86.1 mmol) were stirred at 120° C. for 18 hours. The reaction mixture was poured into methanol, and the precipitate was filtered and washed with methanol. The resulting solid was purified using acetonitrile, methanol and by recrystallization. N-(behenylaminoethyl)aminosuccinamidoylaminohexylamine was obtained as a white crystalline powder (yield 69%, 6.91 g, 11.9 mmol).

[0142] Dissolve N-(docosylaminoethyl)aminosuccinamidoylaminohexylamine (3.25g, 5.59mmol), 37% aqueous formaldehyde (2.73ml) and formic acid (1.55g, 33.7mmol) in 2-propane Alcohol (15ml), stirred at 100°C for 4 hours. The reaction mixture was poured into 1M aqueous sodium hydroxide solution (20 ml) and the crystals were filtered. The obtained crystals were recrystallized with methanol and aceton...

Embodiment 3

[0148] Example 3

[0149]Methyl eicosanoate (18.0 g, 55.1 mmol) and ethylenediamine (16.5 g, 276 mmol) were stirred at 110° C. for 18 hours, and the reactant was washed with methanol, followed by filtration. The filtrate was subjected to solvent distillation, and the obtained residue was purified by recrystallization using hexane. N-eicosylethylenediamine was obtained as white crystals (yield 68%, 13.3 g, 37.5 mmol).

[0150] In N-dimethylformamide (30ml) solution, spent 10 minutes to add N-eicosylethylenediamine (10.0g, 28.2mmol) and triethylamine (5.71g, 56.4mmol), succinic anhydride (3.10 g, 31.0 mmol), stirred at 100°C for 15 minutes. After dissolving succinic anhydride, acetic anhydride (4.32 g, 42.3 mmol) was added dropwise to the reaction crude liquid over 1 minute, followed by stirring at 100° C. for 1 hour. The reaction mixture was poured into water (150 ml), and the precipitate was filtered and washed with water. The precipitate was purified by recrystallization...

Abstract

Provided is a compound capable of thickening a fluidic organic substance to a desired viscosity, and uniformly stabilizing the compositional makeup thereof. The compound according to the present invention is represented by formula (1). In formula (1), R1 represents a monovalent straight-chain aliphatic hydrocarbon group having 10-25 carbon atoms, R2 and R3, which are the same or different, each represent a divalent aliphatic hydrocarbon group having 2, 4, 6, or 8 carbon atoms, a divalent alicyclic hydrocarbon group having 6 carbon atoms, or a divalent aromatic hydrocarbon group, R4 representsa divalent aliphatic hydrocarbon group having 1-8 carbon atoms, and R5 and R6, which are the same or different, each represent a monovalent aliphatic hydrocarbon group having 1-3 carbon atoms or a hydroxyalkyl ether group. L1-L3 each represent an amide bond, and in the case where L1 and L3 are -CONH-, L2 is -NHCO-, and in the case where L1 and L3 are -NHCO-, L2 is -CONH-.

Description

technical field [0001] The present invention relates to a novel compound for thickening and stabilizing a fluid organic substance such as oil, and a solvent composition for producing electronic equipment containing the compound. This application claims the priority of Japanese Patent Application No. 2018-069615 for which it applied to Japan on March 30, 2018, and uses the content here. Background technique [0002] The method of thickening and stabilizing liquids is a very important technology in industry. For example, mayonnaise, salad dressing, etc., which are metastable emulsions, can stabilize their emulsified state for a long time because the water-based ingredients have been stabilized by thickening . Therefore, various viscosity-increasing 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 other hand, 12-hydroxystearic acid is known as a t...
