RESEARCH INTO THE PRODUCTION PROCESS OF BIODIESEL ETHERS BY USING AMINE-CONTAINING CATALYST IN MAGNETIC FIELD.

The production of biodiesel esters by transesterification of corn and sunflower oil with methanol has been analyzed using 1,3-bis (isopropylamino)-propan-2-ol catalyst in 15-45mT magnetic field, at 65°C temperature and 6:1 molar ratio of methanol to oil. Experiments were carried out in three-neck round-bottom flask which is placed in magnetic field produced by electromagnets and equipped with a thermometer, a mixer and a dropping funnel. The yield of the biodiesel ester was 95-97% (by mass) and the duration of the process was 4.5 times shorter with magnetic field when the catalyst is used at 3% by weight relative to oil.
