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

Example Embodiment

[0082] Example

[0083] Hereinafter, the present invention will be described in further detail based on examples, but the present invention is not limited to these examples. In addition, the following "parts" and "%" are based on weight unless otherwise specified. In addition, the test and evaluation are 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 without a cationic group) were used as polystyrene by gel permeation chromatography (GPC) using tetrahydrofuran as a solvent. Measured in ethylene conversion value. In addition, as a measuring instrument, HLC-8320 (manufactured by TOSOH CORPORAT ION) was used, four TSKgel SuperMultiporeHZ-H (manufactured by TOSOH COR PORATION) connected in series were used for the column, and a differential refractometer RI-8320 (manufactured by TOSOH CORPORATIO...

Example Embodiment

[0093] [Manufacturing Example 1]

[0094] (Reactive anion copolymerization of epihalohydrin and glycidyl methacrylate)

[0095] In a glass reactor with a stirrer replaced with argon, 0.032 g of tetra-n-butylammonium bromide and 5 ml of toluene were added, and this was cooled to 0°C. Next, a solution obtained by dissolving 0.029 g (2.5 equivalents with respect 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 the polymerization reaction was carried out 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 liquid was diluted with toluene and poured into...

[0096] [Manufacturing Example 2]

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

[0098] 8.0 g of polyether compound A, 22.0 g of 1-methylimidazole, and 16.0 g of N,N-dimethylformamide obtained in Production Example 1 were added to the glass reaction with a stirrer replaced with argon In the vessel, heat to 80°C. After making the reaction at 80°C for 144 hours, it was cooled to room temperature to terminate the reaction. A part of the obtained reaction solution was extracted and dried under reduced pressure at 50°C for 120 hours. As a result, 15.0 g of a reddish brown resinous substance was obtained. On the resinous substance 1 As a result of H-NMR measurement and elemental analysis, it was confirmed that it was the following polyether compound B: that is, the chlorine groups in all epichlorohydrin units in the polyether compound A obtained in Production Example 1 of the starting material were replaced with Polyethe...

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...
