Daftar Isi:
- Dehydration of ricinoleic of castor oil into mixed of linoleic acid (LA) and conjugated linoleic acid (CLA) named DCO (dehydrated Castor Oil) was conducted by using P2O5 at temperature 125°C and 175°C were held time variety at 1, 2, 3 and 4 hour. Dehydration was maintained under reduced pressure 50 to 70 mmHg, gentle bubbling with Nitrogen , magnetically stirred between 800 to 1000 rpm and 0.1 g Zn powder as antipolymerization agent. The concentration changes of the ricinoleic and DCO followed by contrentation GC. The elucidation of ricinoleic, LA and CLA were analyzed by GC-MS. The result showed that reaction was first order with rate constant (k) was 1.0 × 10-2 h-1 at 125°C and 0.9631 h-1 at 175°C and energy of activation (Ea) was 191.152 kJmol-1and
