1)CH3-CH2-CH2-COOCH2-CH3 + H2O => CH3-CH2-CH2-COOH + CH3-CH2-OH
2) 2HCOOH + 2Li => 2HCOOLi + H2
3) CH3-CH2-COOH + KOH => H2O + CH3-CH2-COOK
4)CH3-CH2-OH + HCOOH => HCOOCH2-CH3 + H2O (реакция этерификации)
5)2CH3-CH2-CH2-COOH + MgO => H2O + (CH3-CH2-CH2-COO)2Mg
6) 2CH3-OH + H3PO4 => CH3-O-CH3 + H2O + H3PO4
