Artigo IPEN-doc 25777 Gallium-67 citrate used as a tracer of acetone production routes2019 - MESQUITA, C.H. de; CALVO, W.A.P.; AOKI, P.E.; SILVA, V.C. da; HARAGUCHI, M.I.; VELO, A.F.; ALVAREZ, A.G.; HAMADA, M.M.In this work the pathway of the chemical product and the kinetics parameters were evaluated in a laboratory plant settled, using 0.4 GBq (10 mL) of 67Ga citrate as radiotracer and 18 NaI(Tl) radiation detectors. The AnaComp program was used to estimate the kinetic para ameters of the acetone production. The yield of the acetone production was estimated by the percentage ratio between the areas under the curve (AUC) of the curve profiles of the final product compartment divided by the concentration found inside the chemical reactor whose result was 87% yield during the first 30 minutes of reaction.Artigo IPEN-doc 24163 Gallium-67 citrate used as a tracer of acetone production routes2017 - MESQUITA, CARLOS H. de; CALVO, WILSON A.P.; AOKI, PEDRO E.; SILVA, VALDIR C. da; HARAGUCHI, MARCIO I.; VELO, ALEXANDRE F.; ALVAREZ, ALEXANDRE G.; PAIXAO, LETICIA B.; HAMADA, MARGARIDA M.In this work the pathway of the chemical product and the kinetics parameters were evaluated in a laboratory plant settled, using 40 GBq of 67Ga citrate as radiotracer and 18 NaI(Tl) radiation detectors. The AnaComp program was used to estimate the kinetic parameters of the acetone production. The yield of the acetone production was estimated by the percentage ratio between the areas under the curve (AUC) of the curve profiles of the final product compartment divided by the concentration found inside the chemical reactor whose result was 87% yield during the first 30 minutes of reaction.
