さほど実用的でないの英語

また、別の社においても、ソルベントレッド１３５を洗浄しＨＣＢを削減する実験（ビーカースケール）を行っているが、より削減効果が大きいと考えられる極性の低い溶媒を利用した場合でも 18%程度の除去率（ＨＣＢ330ppmが270ppmに低減）とさほど大きな低減効果は得られておらず、コスト等を勘案すると、追洗浄は実用的でないと判断される。例文帳に追加

Another company also conducted a (beaker-scale) experiment to examine the effect of cleansing by several kinds of solvents. The result showed that, even when a low-polarity solvent considered to produce a greater reduction effect was used, the reduction effect was not so impressive, with a removal rate of only around 18% (the HCB content was reduced from 330ppm to 270ppm). Thus, considering cost effectiveness, additional cleansing methods mentioned in this section are judged to be not so practical.発音を聞く  - 経済産業省
