Question

Viết PTHH tinh bột -glucozo-ruou etylic-etyl axetat-natri axetat

 

Answer 1

\(\left(-C_6H_{10}O_5-\right)_n+nH_2O\xrightarrow[axit]{t^o}nC_6H_{12}O_6\\ C_6H_{12}O_6\xrightarrow[]{\text{men rượu}}2C_2H_5OH+2CO_2\\ C_2H_5OH+CH_3COOH\xrightarrow[t^o]{H_2SO_{4\left(đặc\right)}}CH_3COOC_2H_5+H_2O\\ CH_3COOC_2H_5+NaOH\rightarrow CH_3COONa+C_2H_5OH\)

Answer 2

C6H12O6-lm->2C2H5OH+2CO2

C2H5OH+CH3COOHto,xt->CH3COOC2H5+H2O

CH3COOC2H5+NaOH-to>CH3COONa+C2H5OH
