2HOOC-(CH2)2-COOH + NaOH → HOOC-(CH2)2-COONa + H2O

HOOC-CH2-CH2-COONa + NaOH → CH3-CH2-COOH + Na2CO3

CH3-CH2-COOH +  NaOH → C2H5COONa + H2O

C2H5COONa + NaOH → C2H6 + Na2CO3

C2H6 →Ni C2H4 + H2

C2H4 + CO + H2 →Kt CH3-CH2-COH

CH3CH2COH + H2 → CH3-CH2-CH2-OH

CH3-CH2-CH2-OH → CH3-CH=CH2 + H2O

CH3-CH=CH2 + O2 →t° CH2=CH-COH + H2O
