(1) 2C2H5OH + O2 \(\underrightarrow{mengiam}\) 2CH3COOH + 2H2O
(2) CH3COOH + C2H5OH ⇌ CH3COOC2H5 + H2O (xt: axit, to )
(3) CH3COOC2H5 + NaOH → CH3COONa + C2H5OH
CH3COONa + HCl → CH3COOH + NaCl
1)
Hai phương pháp là:
1 Dùng quỳ tím: Axit axetic làm quỳ tím hóa đỏ Rượu etylic không làm quỳ tím đổi màu
2 Dùng Na2CO3 hoặc CaCO3: CH3COOH cho khí CO2 thoát ra C2H5OH không có phản ứng
2)
\(C_2H_4+H_2O\rightarrow C_2H_5OH\)
\(C_2H_5OH+O_2\rightarrow CH_3COOH+H_2O\)
\(C_2H_5OH+CH_3COOH⇌H_2O+CH_3COOC_2H_5\)
1. C6H12O6-->C2H5OH-->CH3COOH--->CH3COOC2H5
C6H12O6->2C2H5OH + 2CO2 (1)
C2H5OH + O2 -> CH3COOH + H2O (2)
CH3COOH + C2H5OH->CH3COOC2H5 + H2O (3)
2.,CaC2 + H2O -> C2H2 + Ca(OH)2 (1)
C2H2 + H2 -> C2H4 (2)
n(C2H4)-> (C2H4)n ( trùng hợp )
\(C_2H_5OH+O_2\rightarrow\left(men.giấm\right)CH_3COOH+H_2o\\ CH_3COOH+C_2H_5OH⇌\left(xt,t^o\right)CH_3COOC_2H_5+H_2O\\ 2CH_3COOC_2H_5+Ca\left(OH\right)_2\rightarrow\left(CH_3COO\right)_2Ca+2C_2H_5OH\)
A/ C6H12O6 => (men rượu,to) 2C2H5OH + 2CO2
C2H5OH + O2 => (men giấm) CH3COOH + H2O
2CH3COOH + CaCO3 => (CH3COO)2Ca + CO2 + H2O
(CH3COO)2Ca + H2SO4 => CaSO4 + 2CH3COOH
B/ NaOH + CH3COOH =>(to) CH3COONa + H2O
CH3COONa + HCl => (to) CH3COOH + NaCl
CH3COOH + C2H5OH => (pứ hai chiều, xt:H2SO4đ,to) CH3COOC2H5 + H2O
CH3COOC2H5 + H2O =>(pứ hai chiều, xt: to,H2SO4đ) CH3COOH + C2H5OH
A) C6H12O6----->2C2H5OH+2CO2 (BAY LÊN)
C2H5OH+O2----->CH3COOH+H2O
CH3COOH+Ca(OH)2----->(CH3COO)2Ca+2H2O
(CH3COO)2Ca+H2SO4----->CaSO4+2CH3COOH
