Wyznaczenie kinetyki estryfikacji kwasu laurynowego n-heksanolem, n-oktanolem i n-dekanolem w obecności żywicy jonowymiennej Dowex 50WX8 jako katalizatora

CH3 (CH2 ) 10COOH was esterified with CH3 (CH2 ) 5 OH, CH3 (CH2 ) 7 OH and CH3 (CH2 ) 9 OH at 393–413 K and at molar ratios (alc.:acid) of 3:1–10:1 in the presence of the Dowex catalyst 50WX8 (1.5% by mass). The kinetics of the studied processes were described by the detd. Langmuir-Hinshewood type kinetic equation, the limiting step of which was the surface reaction of CH3 (CH2 ) 10COOH with alcohol. The activation energy decreased in the range of 62–54 kJ/mol in the alcohol series: n-hexanol > n-octanol > n-decanol.
