Green chemical production based on thermal cracking of inedible vegetable oil

This work evaluated the process for heptaldehyde, undecylenic acid and methyl undecenoate production from castor oil, ester of oil ricinoleic acid. Experiments were performed in a continuous pilot-plant scale pyrolysis reactor. Those are very important green chemical products that might be obtained by thermal cracking oil. Transesterification produces ricinoleate its generates heptaldehyde. The temperatures tested 530, 545, 560, 575 ?C, with residence time 17 to 32 s mass flow at 400 g/h mixture materials 25% distilled water. It was observed temperature influence relation bio-oil generated their differences each material. characterized iodine index, number, mass, contents compounds GC-FID chromatography. best result yield desired occurred 530?C, achieving 17.8 % 16.5% For heptaldehyde highest also 530 value 20.7% 15.2%
