Thực hiện các chuyển đổi sau( ghi rõ đi phần ứng) 1, CaCO3-CaO-CaC2-C2H2- C2H4-C2H5OH-CH3COONa 2, C12H22O11-C6H12O6-C2H5OH-CH3COOH-CH3COOC2H5-C2H5OH 3, (-C6H10O5-)n -C6H12O6-C2H5OH-CH3COOH-CH3COOC2H5-C2H5OH Giúp mình với ạ
Chuỗi 1:
\(\left(1\right)CaCO_3\rightarrow\left(t^o\right)CaO+CO_2\\ \left(2\right)CaO+3C\rightarrow\left(2000^oC,lò.điện\right)CaC_2+CO\uparrow\\ \left(3\right)CaC_2+2H_2O\rightarrow C_2H_2+Ca\left(OH\right)_2\\ \left(4\right)C_2H_2+H_2\rightarrow\left(Ni,t^o\right)C_2H_4\\ \left(5\right)C_2H_4+H_2O\rightarrow\left(t^o,H^+\right)C_2H_5OH\\ \left(6\right)C_2H_5OH+2NaOH+CH_3COOH\rightarrow CH_3COONa+C_2H_5ONa+2H_2O\)
thực hiện dãy chuyển hoá C6H12O6 C2H5OH CH3COOH CH3COOC2H5 (CH3COO)2CU C2H5OH
mai thi rồi mà chưa làm sos😭
thực hiện dãy chuyển đổi sau
C2H5 -> C2H4 -> C2H5OH -> CH3COOH -> CH3COOC2H5 -> CH3COONa
C2H5OH -> CO2 -> Na2CO3 -> CH3COONa -> CH3COOH -> (CH3COO)2Zn
C2H6 \(\underrightarrow{t^o}\) C2H4
C2H4 + H2O \(\underrightarrow{axit}\) C2H5OH
C2H5OH + O2 \(\underrightarrow{mengiam}\)CH3COOH
CH3COOH + C2H5OH → CH3COOC2H5 + H2O
NaOH + CH3COOC2H5 → C2H5OH + CH3COONa
Câu 2 viết phương trình phản ứng để thực hiện chuỗi chuyển hoá sau C2H4 C2H5OH CH3COOH Ch3coona4 (CH3COO)2Mg
thực hiện chuỗi biến hóa và ghi rõ điều kiện nếu có:
C2H2 -> C2H4 (1)
C2H4 -> C2H5OH (2)
C2H5OH -> CH3COOH (3)
CH3COOH -> (CH3COO)2Cu (4)
(1) \(C_2H_2+H_2\underrightarrow{t^o,Pd}C_2H_4\)
(2) \(C_2H_4+H_2O\underrightarrow{t^o,xt}C_2H_5OH\)
