1) \(n_{C_2H_4}=\dfrac{8,96}{22,4}=0,4\left(mol\right)\)
PTHH: C2H4 + H2O --axit--> C2H5OH
0,4-------------------->0,4
=> mC2H5OH = 0,4.46.70% = 12,88 (g)
\(V_{C_2H_5OH}=\dfrac{12,88}{0,8}=16,1\left(ml\right)\\ \rightarrowĐ_r=\dfrac{16,1}{50}.100=32,2^o\)
2) \(\left\{{}\begin{matrix}n_{C_2H_5OH}=\dfrac{36,8}{46}=0,8\left(mol\right)\\n_{CH_3COOH}=\dfrac{36}{60}=0,6\left(mol\right)\\n_{CH_3COOC_2H_5}=\dfrac{44}{88}=0,5\left(mol\right)\end{matrix}\right.\)
PTHH: CH3COOH + C2H5OH --H2SO4(đặc), to--> CH3COOC2H5 + H2O
0,5<-------------------------------------------------0,5
LTL: 0,6 < 0,8 => Hiệu suất phản ứng tính theo CH3COOH
=> \(H=\dfrac{0,5}{0,6}.100\%=83,33\%\)
C2H4 + H2O => (140oC, H2SO4đ) C2H5OH
C2H5OH + O2 => (men giấm) CH3COOH + H2O
CH3COOH + C2H5OH => (H2SO4đ, to) CH3COOC2H5 + H2O <pứ hai chiều>
CH3COOC2H5 + NaOH => (to) CH3COONa + C2H5OH
