Description
  • Sebraný kafilerní tuk byl testován z hlediska různých podmínek transesterifikační reakce. Průběh reakce tohoto tuku byl srovnáván s transesterifikací vepřového sádla za stejných podmínek a byly zjištěny výrazné rozdíly mezi průběhem transesterifikace u obou tuků. Optimální přebytek metanolu pro transesterifikaci sádla byl třicetinásobný, pro kafilerní tuk desetinásobný, optimální koncentrace kyseliny sírové byla 1% pro sádlo, 2.5% pro kafilerní tuk. Optimální teplota stejně jako optimální doba reakce byly podobné v obou případech. Složení mastných kyselin je pro oba tuky podobné, ale nikoliv identické. Kafilerní tuk obsahuje větší množství volných kyselin, což může být příčinou zjištěných rozdílů. (cs)
  • Rendering plant fat (RPF) was collected and different conditions were used for transesterification. The course of transesterification of RPF was compared with transesterification of lard under the same conditions. Significant differences were found between transesterification of RPF and that of lard. Optimum methanol excess for lard transesterification was found to be 30-fold, for RPF 10-fold, optimum sulfuric acid concentration was 1% for lard, 2.5 % for RPF. Optimum temperature as well as optimum reaction time was similar in both cases. The fatty acid composition of the both fats is similar, but not identical. RPF contains higher amount of free acid, which could be the reason of observed differences.
