Problems solved by technology

[0004] However, since most ionic liquids are liquid at room temperature but solidify at low temperatures, the low-temperature characteristics are insufficient, and there are restrictions on the use of environmental conditions when applied to industrial processes (for example, they cannot be used at low temperatures. )The problem
In addition, as a method of lowering the melting point of the ionic liquid, a method of adding an organic solvent to the ionic liquid can also be considered, but the addition of a volatile organic solvent will lead to the problem of insufficient flammability suppression effect.

Embodiment

[0083] Hereinafter, the present invention will be described in more detail based on examples, but the present invention is not limited to these examples. In addition, "part" and "%" in the following are based on weight unless otherwise indicated. In addition, tests and evaluations were as described.

[0084] [Number average molecular weight (Mn) and molecular weight distribution (Mw / Mn)]

[0085] (1) The number-average molecular weight (Mn) and molecular weight distribution (Mw / Mn) of the base polymer (polyether compound having no cationic group) were determined as polyphenylene by gel permeation chromatography (GPC) using tetrahydrofuran as a solvent. Measured in terms of ethylene conversion value. In addition, HLC-8320 (manufactured by TOSOH CORPORATION) was used as a measuring device, four TSKgel SuperMultiporeHZ-H (manufactured by TOSOH CORPORATION) connected in series was used as a column, and differential refractometer RI-8320 (manufactured by TOSOH CORPORATION) was us...

[0094] (Living anionic copolymerization of epihalohydrin and glycidyl methacrylate)

[0095] Into a glass reactor with a stirrer replaced with argon, 0.032 g of tetra-n-butylammonium bromide and 5 ml of toluene were added, followed by cooling to 0°C. Next, a solution obtained by dissolving 0.029 g (2.5 equivalents to tetra-n-butylammonium bromide) of triethylaluminum in 0.25 ml of n-hexane was added and reacted for 15 minutes to obtain a catalyst composition. To the obtained catalyst composition, 9.5 g of epichlorohydrin and 0.5 g of glycidyl methacrylate were added, and polymerization reaction was performed at 0°C. After the polymerization reaction started, the viscosity of the solution gradually increased. After reacting for 1 hour, a small amount of 2-propanol was added to the polymerization reaction solution to terminate the reaction. Next, the obtained polymerization reaction solution was diluted with toluene, and poured into 2-propanol to obtain 8.3 g of a white rubber...

[0097] (The epichlorohydrin unit in the polyether compound A is based on the quaternization of 1-methylimidazole)

[0098] 8.0 g of polyether compound A obtained in Production Example 1, 22.0 g of 1-methylimidazole, and 16.0 g of N,N-dimethylformamide were added to a glass reactor with a stirrer replaced with argon. In a container, heat to 80°C. After reacting at 80° C. for 144 hours, the reaction was terminated by cooling to room temperature, and a part of the obtained reaction solution was extracted and dried under reduced pressure at 50° C. for 120 hours to obtain 15.0 g of a reddish-brown resinous substance. the resinous substance 1 As a result of H-NMR measurement and elemental analysis, it was confirmed that it was a polyether compound B in which all the chlorine groups in the epichlorohydrin units in the polyether compound A obtained in Production Example 1 of the starting material were substituted with Polyether compound B having a 1-methylimidazolium halide group in...

Abstract

Provided is an ionic composition comprising an ionic liquid and a polyether compound having cationic groups. According to the present invention, it is possible to provide the ionic composition which has extremely low vapor pressure and therefore suppressed flammability, and which has excellent low-temperature properties.

Description

technical field [0001] The present invention relates to an ionic composition containing an ionic liquid. More specifically, the present invention relates to an ionic composition having an extremely low vapor pressure, suppressed flammability, and excellent low-temperature properties. Background technique [0002] In general, industrial processes using organic solvents are widely used in the chemical industry, but since organic solvents are flammable, this has become an urgent problem to be solved from the viewpoint of safety. [0003] In addition, as a liquid other than an organic solvent, the development of an aqueous solution system process has been studied. However, water generally causes damage to electronic equipment and corrosion of metals such as iron, so the development of its technology is bound to be limited. Therefore, the use of non-volatile ionic liquids has been studied as a third solvent instead of these (for example, refer to Non-Patent Document 1). For exa...
