| 1. | Aldehydes possess anesthetic properties . 醛类具有麻醉的作用。 |
| 2. | This reaction involves disproportionation of the aldehyde . 这个反应就是醛的歧化作用。 |
| 3. | Both the alcohols and aldehydes are secondary products of the oxidation . 醇和醛两者为氧化的次级产物。 |
| 4. | The aldehyde solution was then cooled to 0℃ by an external ice bath. 由外面的冰浴将这种醛的溶液冷却到0。 |
| 5. | There are several examples of a one-carbon degradation leading to aldehydes . 有一些减少一个碳原子制备醛的实例。 |
| 6. | The reaction of sulfate with aldehydes and ketones has been known for many years . 大家知道硫酸盐能与醛类和酮类反应已有许多年了。 |
| 7. | In reality, readily characterizable high polymers are formed only from aliphatic aldehydes rcho . 事实上有代表性的高聚物仅仅是由脂肪醛RCHO制得的。 |
| 8. | The yields of aldehydes produced in this sequential process are comparable to the two-step method . 用此法制得的醛,其产率与用两步法可制得的产率不相上下。 |
| 9. | Reaction is carried out under a fractionating column that allows aldehyde to pass but returns alcohol to the reaction vessel . 反应是在装有分馏柱的反应器中进行的,分馏柱能让醛通过但使醇回流到反应器中。 |
| 10. | Aldehydes and other carbonyl compounds are most easily polymerized by essentially anionic mechanisms on account of the stability of alkoxide ions . 醛类和其他的羰基化合物,由于烷氧基离子的稳定性,最容易通过本质上是负离子的机理进行聚合。 |
