Synthesis and Reactions of Pentiptycenes and Their Derivativestycene . was synthesized in about 10 % total yield by a three-step route starting from 2-aminotriptycene .. Similar to the way for the synthesis of triptycene, the Diels–Alder reaction between anthracene and benzyne was also the key process to pentiptycene.

Chuan-Feng Chen,Ying-Xian Maverall operational budget. Previous studies reveal an insignificant bio-sludge reduction from CAS while maintaining desired operating parameters including sludge retention time (SRT) and return activated sludge (RAS). The reason is being referred to higher organic portion present in tannery influent
