醋酸異戊酯的理論產量為多少?

Question

請問一下,醋酸異戊酯(香蕉油)的理論產量為多少?
我是取17.6克的異戊醇和30克的冰醋酸

Answer 1

異戊醇：C5H11OH = 12*5 + 1*12 + 16*1 = 88
莫耳數：m = W/M = 17.6/88 = 0.2(mol)
冰醋酸(乙酸)：CH3COOH = 12*2 + 1*4 + 16*2 = 60
莫耳數：m = W/M = 30/60 = 0.5(mol)
C5H11OH + CH3COOH --> C5H11-CH3COO + H2O
異戊醇0.2mol為限量試劑，醋酸異戊酯(C5H11-CH3COO)理論產量為0.2mol。
醋酸異戊酯： C5H11-CH3COO = 12*7 + 1*14 + 16*2 = 130
m = W/M = W/130 = 0.5 --> W = 130*0.5 = 65(g)
答案：醋酸異戊酯理論產量為0.2莫耳、65克

C5H11OH CH3COOH --> C5H11-CH3COO H2O

異戊醇0.2mol為限量試劑，醋酸異戊酯(C5H11-CH3COO)理論產量為0.2mol。

醋酸異戊酯： C5H11-CH3COO = 12*7 1*14 16*2 = 130

m = W/M = W/130 = 0.2 --> W = 130*0.2 = 26(g)

答案：醋酸異戊酯理論產量為0.2莫耳、26克

m = W/M = W/130 = 0.2 --> W = 130*0.2 = 26(g)

在這個算試中，第一次乘上0.5mol是錯誤的，理論產量是0.2mol應該乘上0.2mol才對。
