metanol --> metanal --> kw. metanowy --> mrówczan wapnia
CH3OH + CuO---->HCHO + Cu + H2O
HCHO + Ag2O----->HCOOH + 2Ag
2 HCOOH + Ca----->(HCOO)2Ca + H2
2) Otrzymywanie octanu wapnia
2 CH3COOH + Ca----->(CH3COO)2Ca + H2
2 CH3COOH + CaO----->(CH3COO)2Ca + H2O
2 CH3COOH + Ca(OH)2----->(CH3COO)2Ca + 2H2O
3) Równania reakcji:
a) C17H33COOH + H2 -->C17H35COOH
b) C15H31COOH + NaOH -->C15H31COONa + H2O
c) C2H5OH + O2 -->CH3COOH + H2O
d) HCHO + Ag2O -->HCOOH + 2Ag
e) 2 CH2 = CH2 + O2 --> 2 CH3CHO (na strzałce"katalizator")
4) Za pomocą próby Tromera i Tollensa udowodnij,że aldehyd octowy ma własciwosci redukujace.
Próba Tollensa
CH3CHO + Ag2O---->CH3COOH + 2Ag
Próba Tromera
CH3CHO + 2Cu(OH)2------>CH3COOH + Cu2O + 2H2O
