2.反应碱性过强其结果磺胺较多，磺胺醋酰次之，双乙酰物较少;碱性过弱其结果双乙酰物较多，磺胺醋酰次之，磺胺较少，为什么?<br><br>答:因碱度过大磺胺双醋酰易水解成磺胺，且易引起磺胺醋酰水解成磺胺;而因碱度过小时，反应过程中易生成较多的N-乙酰磺胺，且磺胺双醋酰分子结构中的N-乙酰基不易水解下来， 所以反应碱性过强其结果磺胺较多，磺胺醋酰次之，双乙酰物较少;碱性过弱其结果双乙酰物较多，磺胺醋酰次之，磺胺较少。

2. the reaction is too alkaline. The result is that sulfanilamide is more than sulfadiacetic acid, and diacetyl is less.<br>Answer: Sulfonamide diacetyl is easy to hydrolyze to sulfonamide because of its high alkalinity, and it is easy to cause sulfonamide acetyl to hydrolyze to sulfonamide; but when the alkalinity is too small, more N-acetylsulfonamide is easily formed in the reaction process, and N-acetyl in the molecular structure of sulfonamide diacetyl is not easy to hydrolyze, so the reaction with excessive alkalinity results in more sulfonamide, followed by sulfonamide acetyl, and less diacetyl. Diacetyl is more, sulfonamide acetamide is next, sulfonamide is less.<br>
