帮忙翻译一段话(腐蚀方面)
|
|||
| 温度对吡咯烷酮(pyrrolidone)的腐蚀性影响相对较大，对咪唑（imidazole）和吡啶(pyridine)离子液体影响较小，这是因为吡咯烷酮(pyrrolidone)热稳定性较低。阳离子上接入磺酸基的(pyrrolidone)相比于同类型的腐蚀速率大，因为磺酸基能增强其酸性，导致腐蚀性增强。 |

| Due to the thermal unstability of pyrrolidone, the influence of temperature toward causticity of ionic liquid of pyrrolidone is relatively bigger than that of imidazole and pyridine. The corrosion rate of pyrrolidone with cations attached by sulfonyl group is comparatively bigger than same type because sulfonyl group increases the acidity, which leads to stronger causticity. |

| Temperature has relatively larger influence on the corrosivity of pyrrolidone, and less influence on that of imidazole and pyridine because of low thermo-stability of pyrrolidone. Since pyrrolidone enables cation’s acidity and increases its corrosivity, the corrosive rate of cation with pyrrolidone added are larger than that of other types. |
