Lab-scale batch reactor

Behr et al. [114] investigated the selective formation of octadienyl phenol ethers in a liquid-liquid biphasic loop reactor. Although the Pd/TPPTS system showed good activity and selectivity (86% conversion with 74% selectivity towards the telomer after 5 h) in a lab-scale batch reactor, telomer yields in the loop reactor were insufficient for efficient phase separation. Telomerization with phenol was therefore deemed unsuitable for this type of reactor. The authors also noted that the C-allylated octadienyl phenol product rather than the telomerization product became the main product after 6 h of reaction, attributing this to a metal-catalyzed Claisen-type rearrangement. 

Villano and co-workers [36] presented the production and recovery of PHA using mixed microbial cnltnres (MMC). The process was carried out sequentially from lab-scale batch reactor, for culture selection, and then PHA accumulation reactor and extraction reactor. It is a continuous process and is at a high process rate for at least 4 months. In this study, IM NaOH and NaClO with 5% active liquid chlorine were investigated. It was found that digestion with... 

This consecutive reaction shows high sensitivity to mixing as well as to temperature variations. Whereas in a lab-scale batch reactor 63% of the target product C is obtained only at temperatures lower than 218 K, similar selectivity...
