acidul stearic = CH3-(CH2)16-COOH asadar
Alcanii superior care pot da astfel de reactie sunt cele C20....C25
=> ca ce mai simpla hc. de la care provine acidul stearic poate fi CH3-(CH2)16-CH2-CH2-(CH2)16-CH3
=>
a g ................................................................................... 2,84 g
CH3-(CH2)16-CH2-CH2-(CH2)16-CH3 + 2O2---> 2CH3-(CH2)16-COOH + 2H2O
506 g/mol ..................................................................... 2x284 g/mol
=> a = 506x2,84/2x284 = 2,53 g
