https://www.selleckchem.com/products/pexidartinib-plx3397.html Development of preparative methods for the isolation of chiral molecules has been considered challenging by conventional unit operations due to their identical physical and chemical properties. This has evolved chiral stationary phases for the separation of chiral components using chromatography technique. However, separation method using chiral adsorbents requires high pressure, are expensive, and have low productivity. Generation of bulk quantities purified nebivolols using the available high pressure chiral separation methods is impractical and operating cost-intensive. Thus, there is a need to develop economical methods using nonchiral adsorbents for the purification of nebivolols or similar active ingredients. The present work demonstrates a unique and scalable tandem two-column method for the separation of isomers of nebivolol using inexpensive reverse phase adsorbents. The first column of the scheme causes removal of charged and nonisomeric impurities whereas tandem operation of second column increases resolution of d-nebivolol and l-nebivolol. The maximization of separation due to tandem operation of second column causes enhancement of the throughput of the process. The developed preparative process produces >98% purity of both d-nebivolol and l-nebivolol with overall loading capacity of 56 g (L of adsorbent)-1 and productivity of 20 g L-1 day-1 .The purpose of this study was to determine the effect of high-intensity ultrasound (HIU) on the physical properties of an all-purpose shortening and to evaluate how these properties changed during storage (48 hr; 4, 12, and 24 weeks) at 5 °C and 25 °C. Samples were crystallized at 30 °C for 60 min with and without the application of HIU (20 kHz; 3.2 mm-diameter tip, 168 µm amplitude, 10 s). After crystallization, physical properties, such as hardness, elasticity, melting behavior, and solid fat content (SFC), were measured. These properties were also mea
