Embodiment 1~6、20

[0093] [embodiment 1~6,20, comparative example 1~6,10] the dissolution stability test of PFPE solution

[0094] 28.5 g of the solvents shown in Table 1 were added to a 50 mL glass screw bottle. Next, 1.5 g of PFPE shown in Table 1 was added to the screw bottle, and mixed well to obtain a uniform solution. It was stored under light shielding at room temperature, and the state of the solution after 0 day (immediately after mixing PFPE and the solvent), 3 days, and 10 days was observed with the naked eye. The state where the solution was colorless and transparent (no turbidity) was evaluated as "◯", the state where turbidity occurred was evaluated as "△", and the state where coloring, gelation, or two-layer separation occurred was evaluated as "×". The results are shown in Table 1.

Embodiment 7~8、 comparative example 7

[0100] [Examples 7-8, Comparative Example 7] Storage stability test

[0101] Add 80 g of the solvents shown in Table 2 to a 100 mL screw bottle, and let stand at room temperature for 10 days. After standing still for 10 days, take 50g of solvent from the screw bottle, add 50g of water prepared to be neutral, and fully mix. Thereafter, the two layers were left still and separated, and the pH of the aqueous layer was measured using a pH meter (pH meter MM-60R manufactured by TOA-DKK). The case where the pH did not change before and after the test was evaluated as "◯", and the case where the pH dropped to 4 or less was evaluated as "×". The results are shown in Table 2.

Embodiment 9~10、 comparative example 8

[0104] [Examples 9-10, Comparative Example 8] Material Suitability Test

[0105] Add 20g of the solvent shown in Table 3 and 1 piece of ABS resin test piece (30mm×15mm×2mm) into a 30mL screw bottle, and completely immerse the test piece in the solvent, set the temperature of the solvent to 40°C, and keep it for 1 Hour. Then, the test piece was taken out and allowed to dry naturally. The state of the dried test piece was confirmed visually. The case where no change was observed in the size and surface of the test piece from before immersion was evaluated as "◯", and the case where a dimensional change or a significant change in appearance was observed was evaluated as "×". The results are shown in Table 3.

Abstract

One of the problems addressed by the present invention is to provide a solvent composition which has low adverse impact on the global environment and which has excellent stability when a compound having a perfluoropolyether (PFPE) group is in a solution state. This problem is solved by providing a solvent composition which dissolves a compound having a perfluoropolyether (PFPE) group, and which has Z-1,2-dichloro-3,3,3-trifluoropropene(1223xd(Z)) as a main component.

Description

technical field [0001] One embodiment of the present invention relates to a solvent composition for dissolving a composition mainly composed of a compound having a perfluoropolyether group (hereinafter also referred to as “PFPE group”). Background technique [0002] Compounds having a PFPE group generally have various characteristics such as thermal stability, chemical stability, and excellent electrical insulation. Therefore, compounds having a PFPE group can be used, for example, in the semiconductor industry as working oils for vacuum pumps, lubricants for magnetic recording media, release agents, adhesives for optical members, and the like. [0003] Compounds having a PFPE group are generally difficult to dissolve in compounds other than fluorine-containing compounds, as a solvent used when preparing a lubricant solution containing a compound having a PFPE group, or for removing from an article to which a compound having a PFPE As cleaning agents for removing this compo...
