Abstract

The prospects of using asphaltenet and resind of industrial vacuum oil residue as a feedstock for the production of pure vanadyl porphyrins are shown. Vanadyl porphyrins are separated from petroleum objects via extraction with DMFA with subsequent purification by column chromatography on silica gel and sulfonic cation exchanger. The composition of resulting vanadyl porphyrins is studied using matrix-assisted laser desorption/ionization mass spectrometry (MALDI) and high-performance liquid chromatography (HPLC). The metalloporphyrins obtained in this way can be used as bases for the creation of catalysts for different chemical processes as an alternative to their synthetic production.

从重油渣油中获得纯氧钒卟啉以形成不同工艺的催化剂基础

摘要

展示了使用沥青质和工业减压渣油树脂作为原料生产纯氧钒卟啉的前景。通过用 DMFA 萃取，随后通过硅胶柱色谱和磺酸阳离子交换剂纯化，将氧钒卟啉从石油物体中分离出来。使用基质辅助激光解吸/电离质谱 (MALDI) 和高效液相色谱 (HPLC) 研究所得氧钒卟啉的组成。以这种方式获得的金属卟啉可用作为不同化学过程创建催化剂的基础，作为其合成生产的替代品。
