Sažetak
Biodiesel is produced by transesterification of vegetable oil (triglycerides) with alcohol, mainly methanol and ethanol. Usually NaOH and KOH are used as catalyst, but they cause saponi-fication, if a higher content of water or free fatty acids is present, which is common for waste cooking oils. This study examines the application of N, N ′, N″-tris(3-dimethylaminopropyl)-gua-nidine as a catalyst for the transesterification of waste cooking oil with methanol, ethanol, 1-propanol, 2- propanol, 1-butanol, 2-butanol, iso-butanol, 1- pentanol, iso-pentanol, 1-hexanol, 1-heptanol, 1- octanol, 1-decanol, 1-dodecanol, and benzyl- alcohol. Conversions in the range from 70 up to 99 mol % (except for 2-propanol and 2-buthanol) were obtained after 5 h at 50°C with 3 wt. % of catalyst and at 1:6.2 molar ratio of vegetable oil and alcohol. Phase separation of biodiesel and glycerol immediately after the transesterification was present only for biodiesel produced with methanol, ethanol and 1-butanol.
