[求助] 请教合成操作细节

Aging time was fixed at 24 h in order to reach conditions near equilibrium. At this point, the solution was cooled at room temperature with an ice
bath, and the solid was separated by magnetic decantation and washed several times with distilled water.以上是合成过程中的步骤,请问有懂的朋友解释一下,这个用冰水浴是在24截止后立马用冰水浴还是等降温后再用冰水降温。

When the precipitation was completed, nitrogen was allowed to pass for another 3 min, and the system was undisturbed and heated to 90°C for 24 h in a Teflon
autoclave. Aging time was fixed at 24 h in order to reach conditions near equilibrium. At this point, the solution was cooled at room temperature with an ice bath, and the solid was separated by magnetic decantation and washed several times with distilled water.我没说清楚,应该是在保温结束后用冰浴冷却吧,我也认为是冷却后再冰浴没用处了
