1·Using the enzyme sarcosine oxidase on the samples produced the chemical compound formaldehyde. Through oxidation, the formaldehyde in turn produced formic acid.
在样本中使用这种肌氨酸氧化酶能够产生化学复合物甲醛。甲醛通过氧化，反过来又可以产生甲酸。
2·Formic acid efficiently dissolves and removes calcium based deposits, as well as rust, scale and iron oxide deposits.
甲酸能有效地溶解和去除钙质沉积物，包括锈、水垢和氧化铁沉积物。
3·Formic acid concentration, activated carbon dosage and initial hydrogen peroxide concentration, reaction temperature affect the oxidative removal of thiophene.
甲酸浓度、活性炭加入量、过氧化氢初始浓度及温度对噻吩硫的氧化脱除均有影响。
4·In addition, due to its simplicity, formic acid is also chosen as model for studying biological systems exhibiting the organic acidic type of bonding.
另外，由于甲酸的简单性，它也经常被选为研究体现有机酸成键类型的生物体系的模型。
5·Aromatic dinitriles were prepared with excellent yields by refluxing the corresponding aromatic dialdehydes with hydroxylamine hydrochloride in 85% formic acid or glacial acetic acid.
芳香族二醛与羟胺盐酸盐在85%甲酸或冰醋酸中回流可制备相应的芳香族二腈。方法简便，产率高。
