PROBLEM TO BE SOLVED: To provide an oil for carbon fiber precursor acrylic fiber, which effectively prevents fusion among single fibers in a production process of carbon fiber bundles, suppresses operability decline, and is capable of providing in high productivity well-bundled carbon fiber precursor acrylic fiber bundles and carbon fiber bundles of excellent mechanical properties, to provide an oil composition for carbon fiber precursor acrylic fibers, and to provide an oil-treating liquid for carbon fiber precursor acrylic fibers.SOLUTION: There are provided an oil for carbon fiber precursor acrylic fiber comprising two or more compounds selected from the group consisting of specific compounds A, B, C, D, E, and F, an oil composition for carbon fiber precursor acrylic fiber containing the oil, and an oil-treating liquid for carbon fiber precursor acrylic fiber obtained by dispersing the oil composition in water. |
