The article was titled 《Significant improvement in conversion efficiency of isonicotinic acid by immobilization of cells via a novel microsphere preparation instrument》, and you may find the article in Bioresource Technology.Safety of 4-Cyanopyridine The information in the text is summarized as follows:
An instrument for the automatic preparation of microspheres was designed and manufactured, and by which cells were immobilized as efficient biocatalyst with small particle diameter, high crosslinking uniformity, and high porosity. The concentration of polymer solution, crosslinking agent and other conditions for preparing the cells microspheres were determined, and the conversion conditions of isonicotinic acid from 4-cyanopyridine were optimized to minimize mass-transfer limitations, and improve thermal and storage stability. The immobilized cells microspheres, which were continuously used for 23 batches, showed a total transformation capacity of 4.6 mol/L 4-cyanopyridine and a cumulative mass of 566.31 g/L of isonicotinic acid, which demonstrated the potential of the durable biocatalyst with efficient conversion capacity. In the part of experimental materials, we found many familiar compounds, such as 4-Cyanopyridine(cas: 100-48-1Safety of 4-Cyanopyridine)
4-Cyanopyridine(cas: 100-48-1) belongs to pyridine. Pyridine is a relatively complex molecule and exhibits a number of different bands in IR spectra. Among others, the bands characterizing the ν8a and ν19b modes have been found to be sensitive to the coordination or protonation of the molecule. Note that the band that is diagnostic for the PyH+ ion at about 1545 cm− 1 (ν19b mode) does not overlap with any of the other bands.Safety of 4-Cyanopyridine
