氨化

Nefedipine was synthesized with m-Nitrobenzaldehyde,ethyl acetoacetate,ammonium acetate.

以间硝苯甲醛,乙酰乙酸乙酯,氨化试剂为原料。

The dissolved oxygen had greater effects on heterotrophic bacteria,ammonifying bacteria and nitrifying bacteria.

溶解氧对异、氨化、硝化有较大影响。

In this paper,W amino polyoxyalkylene were synthesized by two steps.In the first step,polyoxyalkylene were brominated.In the second,the brominated polyoxyalkylene were aminated.

本文用聚乙二醇先溴代，再氨化的二步合成法，合成了胺单取代聚乙二醇衍生物。

If the wastewater concentration was too high, it would stimulate fungus, aminate bacteria, denitrifying bacteria and some anaerobic bacteria to propagate.

污水浓度过大，会刺激土壤中真、氨化、反硝化及一些的繁殖。

Some calculations are made for the utilization of waste heat in the tail gas from preneutralization,pipe reaction and secondary ammoniation sections.

介绍预中和反应的尾与管式反应及二次氨化反应尾混合洗涤后的尾余热利用的有关计算。
