Sublimation of acetanilide

Webrecrystallization or sublimation and liquids via distillation. In this experiment, students will purify crude acetanilide via recrystallization from water (Scheme 1). Scheme 1. … Websublimation occurs is called the sublimation point. Other solids decompose rather than melt. The temperature at which a solid decomposes is the decomposition point. While both sublimation points and decomposition points are useful in helping to identify compounds, neither is very helpful in establishing the purity of a compound. 2
