Abstract

The present invention relates to the field of preparing positive electronic radioactive medicine, especially the preparation apparatus and process of 2-fluoro-8 substituent-2-deoxy-beta-D-glucose. The apparatus includes wind bath for heating and cooling the reaction bottle, and negative perssure transmission unit for ultimate product with reduced radioactivity loss, shortened time and raised synthesis efficiency. The technological process combined acid-alkali hydrolysis without possibility of elimination reaction in the 2-position, and it has short hydrolysis period and high radioactive purity and chemical purity of the prepared medicine.

Description

technical field [0001] The invention relates to the field of preparation of positron radiopharmaceuticals, in particular to a radiopharmaceutical 2-fluoro-18-generation-2deoxy-β-D-glucose ( 18 F-FDG) manufacturing equipment and process. Background technique [0002] 18 F-FDG is the most widely used radiopharmaceutical in PET research. It is widely used in the diagnosis of malignant tumors, the determination of glucose metabolism in the myocardium and brain, etc. Due to its importance and wide applicability, since its synthesis was first reported in 1977, many literatures have reported 18 F-FDG preparation, and developed a variety of automated synthesis equipment. At present, everyone adopts the selective stereonucleophilic reaction reported by Hamacher K in 1986, and can choose to synthesize 2-fluoro-18 generation-2 deoxy-β-D-glucose (Hammacher K, J NuclMed, 27, 235 (1986), p235-238). [0003] The F-18 ion becomes a naked ion after K2.2.2 complex...
