Disperse 104 was synthesized by a process starting from diazotization of 2-chrolo-4-nitroaniline, followed by coupling, reduction; and then re-diazotization and re-coupling.

以2 - 氯- 4 - 硝基苯胺为原料，先经过重氮化、偶合反应合成出对硝基偶氮苯，经还原后再进行重氮化与偶合反应制备出最终产品分散黄104 。

Of course, the whole notion of "DE or re - coupling" needs to be put into the appropriate context.

当然，我们需要把“脱钩或再挂钩”整个概念放在合适的背景之下。
