An automated H-Cube platform was designed, constructed and validated by Clapham et al. [26], to perform deprotection reactions and produce compound libraries. This special instrument includes 48 starting material vials for automated injection into the flow reactor. In producing the Cbz deprotected library, complete conversions and a 93% average crude yield were obtained over Pd/C catalyst at 60°C using full hydrogen mode. For the second library, 4-benzyloxy benzoic acid was coupled with a series of amides. The deprotection performed in H-Cube resulted in eomplete conversions to the products and 88% average crude yield. [Pg.402]

The 48-channel MCFB reactor and the catalyst synthesis workflow components were similarly validated in experiments where bulk samples were prepared in library format, screened in the array format, and the data compared with known examples. This part of the workflow was used for initial hit validation and to opti-... [Pg.9]

To illustrate the functionality of the system a validation library was prepared and introduced into the reactor system. With the goal of achieving an optimal fluid distribution with a minimal pressure drop over the 96 reactor channels we used multichannel ceramic bodies ( miniliths ) as supports, which are impregnated with the corresponding catalyst precursor solutions in an automatic manner (for suitable technical solutions see Section 2). At each of the 96 reactor positions, a candidate material modified by impregnation is available for testing. The shadowed scheme... [Pg.33]

Based on these preliminary results, a small library of NCN-pincer nickel-containing metallodendrimers was prepared by Van Koten et al. in order to investigate the factors that can affect the catalyst performance and their applicability in nanofiltration membrane reactors [35,36]. The strategy in this... [Pg.9]

According to this definition, the relative activities of two catalysts can be obtained without knowing function /, but they may be readily compared by fixing the temperature and varying the Weight Hourly Space Velocity (WHSV), to obtain a chosen degree of conversion [54]. This can be done with the MFBR system [34, 49], where space velocity can be varied individually for each reactor across the 48 library members. [Pg.384]
