Porphyrinoids CO 2 is a cheap abundant and nontoxic C1 source and the chemical conversion of CO 2 into useful organic compounds has become increasingly important In their Full Paper on page 6556 ff C Maeda J Hasegawa T Ema et al describe the synthesis of bifunctional metalloporphyrins with quaternary ammonium bromides at the meta para or ortho positions of the meso ‐phenyl

Quaternary ammonium compounds (quats) such as benzalkonium chloride (see Fig 1 34 for the chemical structure) are a large group of related compounds Some concentrated formulations have been shown to be effective low-level disinfectants Typically quats do not exhibit efficacy against difficult-to-kill nonenveloped viruses such as norovirus rotavirus or poliovirus

The quaternary ammonium compounds in spite of their weak performance against un-enveloped viruses have strengths that contrast with many of bleach's weaknesses: they do have some ability to act as a cleaner as well as a disinfectant (depending on concentration and formulation) they have better – though not complete – activity in the face of organic matter and they are relatively

The quaternary ammonium salt used was cetyl trimethyl ammonium bromide (C 16 H 33 (CH 3) 3 N + Br − FW: 364 g/mol) labelled CTAB supplied by Vetec Remscheid Germany and it was used without any further purification Analytical grade reagents (glacial acetic acid and sodium hydroxide) were purchased from Vetec and were used as received All of the solutions were prepared with distilled

Ammonium (NH 4 +) — or its uncharged form ammonia (NH 3) — is a form of nitrogen which aquatic plants can absorb and incorporate into proteins amino acids and other molecules High concentrations of ammonium can enhance the growth of algae and aquatic plants Bacteria can also convert high ammonium to nitrate (NO 3-) in the process of nitrification which lowers dissolved oxygen
