Question

Viết phương trình hóa học thực hiện các chuyển hóa sau:

1/       CaC₂ --> C₂H₂ --> C₂H₄ --> P.E

2/       Tinh bột --> Glucozơ --> Rượu etylic --> Axit axetic--> Etyl axetat

3/       Đibrom etan <-- A --> Rượu etylic --> Etyl axetat --> Natri axetat

Answer 1

\(1,CaC_2+2H_2O\rightarrow Ca\left(OH\right)_2+C_2H_2\uparrow\\ C_2H_2+H_2\xrightarrow[t^o]{Pd}C_2H_4\\ CH_2=CH_2\xrightarrow[xt]{t^o,p}\left(-CH_2-CH_2-\right)_n\)

\(2,\left(-C_6H_{10}O_5-\right)_n+nH_2O\xrightarrow[t^o]{axit}nC_6H_{12}O_6\\ C_6H_{12}O_6\xrightarrow[\text{men rượu}]{H^+,t^o}2C_2H_5OH+2CO_2\uparrow\\ C_2H_5OH+O_2\underrightarrow{\text{men giấm}}CH_3COOH+H_2O\\ C_2H_5OH+CH_3COOH\xrightarrow[t^o]{H_2SO_{4\left(đặc\right)}}CH_3COOC_2H_5+H_2O\)

\(3,A:C_2H_4\\ C_2H_4+Br_2\rightarrow C_2H_4Br_2\\ C_2H_4+H_2O\xrightarrow[axit]{t^o}C_2H_5OH\\ C_2H_5OH+CH_3COOH\xrightarrow[H_2SO_{4\left(đặc\right)}]{t^o}CH_3COOC_2H_5+H_2O\\ CH_3COOC_2H_5+NaOH\rightarrow CH_3COONa+C_2H_5OH\)
