Phosphinic and Phosphonic Acids I: Protonation and Complex Formation Equilibria of Some Substituted Ethane-1,1,2-tris-(P-methyl-phosphinie Acids)
نویسندگان
چکیده
Oligophosphonic and -phosphinic acids roused significant interest as complexing agents and gained importance in many fields of practical chemistry. Particular attention was drawn towards molecules having two or more phosphonic or phosphinic acid substituents in vicinal and/or preferably geminal positions attached to the ethane fragment. Novel synthetic procedures [1 -4 ] led to structures related to a generalized for mula:

Potentiometeric study of protonation and complex formation of some amino acids with Zn (II) , Co(II) and Ni (II) in aqueous solution
The stability constants and complexation reaction between L-glutamine, L-arginine andglycine with Zn (II) , Co (II) and Ni (II) were studied potentiometrically in aqueous solution at25° C and μ=0.1 M KNO3. The overall stability constants log β´s of all species are obtained bycomputer refinement of pH-volume data using BEST computer program. Several models weretested and the lowest δFIT, the bes...
متن کاملPhosphonic acid: preparation and applications
The phosphonic acid functional group, which is characterized by a phosphorus atom bonded to three oxygen atoms (two hydroxy groups and one P=O double bond) and one carbon atom, is employed for many applications due to its structural analogy with the phosphate moiety or to its coordination or supramolecular properties. Phosphonic acids were used for their bioactive properties (drug, pro-drug), f...
متن کاملEasily Accessible Thermotropic Hydrogen‐Bonded Columnar Discotic Liquid Crystals from Fatty Acid– Tris‐Benzoimidazolyl Benzene Complexes
We report the formation of easily accessible hydrogen-bonded columnar discotic liquid crystals (LCs) based on tris-benzoimidazolyl benzene (TBIB) and commercially available fatty acids. By increasing the length of the fatty acid, the temperature range of liquid crystallinity was tuned. Introducing double bonds in octadecanoic acid lowered the crystallization temperature and increased the temper...

In this study, multi-walled carbon nanotubes modified by N-(3-nitro-benzylidene)-N-trimethoxysilylpropyl-ethane-1, 2-diamine (NBATSPED-MWCNTs) was prepared as a low-cost and non-toxic adsorbent. These materials was characterized by different techniques such as SEM, XRD and FT-IR and subsequently was used for the removal of humic acids (HAs) from aqueous solution. The influence of various opera...
