Diethanol complex

Piridicillin (27) is made by ]T-acylating amoxycillin with a rather complex acid. The synthesis begins by reacting j, ]i-diethanol amine with. c ty i zene-sul fonyl chloride to give 23. Conversion (to 24) with ethyl formate and sodium... 

A method suitable for quantification of the functional class of bis(ethanol)amine antistatics, which lack UV chromophores, consists of reaction with methyl orange [53]. Atmer 163 (alkyl-diethanol amine) has been determined as a yellow complex at 415 nm after interaction with a bromophenol/cresole mixture [64]. Hilton [65] coupled extracted phenolic antioxidants with diazotised p-nitroaniline in strongly acidic medium and carried out identification on the basis of the visible absorption spectrum in alkaline solution. The antioxidant Nonox Cl in... 

Thiomorpholin-3-one forms Cu(tm)2X2 (X = Cl, Br, or I), Cu2(tm)2(S04)2 and [Cu(tm)4](N03)2 which are probably S-bonded in contrast to the O-bonding found in the nickel(n) complexes.602 Diethanol dithiocarbamic acid forms Cu[(HOC2H4)2-NCS2]2 which is a monomeric planar CuS4 chromophore in solution, but Cu - S interaction probably occurs between neighbouring molecules in the solid state.603... 

In addition to the DB, the fractionation process is quite heavily influenced by the different chemical nature of the byproducts, and also provides the possibility of their separation and identification. One example of the chemically controlled elution fractionation was that of a hb poly(urea urethane) this was the product of a complex AA + B2B reaction between 2,4-toluylene diisocyanate (TDI) and diethanol amine (DEA), additionally end group-modified with phenylisocyanate [94]. Whilst the fractionation of this sample led to a bimodal distribution, an analysis of the fi actions (using SEC with RI detection) showed clearly that the first peak of the distribution belonged to a low-molar-mass substance, identified by NMR and MALDI-TOF as the byproduct diphenylurea (Figure 24.9) [154]. 

It has been, for instance, possible to obtain rate constants, diffusivities and solubilities from measured "mass transfer with chemical reaction" rates in a simple model equipment (9). Nevertheless, there are still controversies on the physicochemical properties and kinetics of some common systems, such as reaction of CO2 with ethanolamines (27,28), and catalyzed oxidation of sodium sulphite (29). Indeed, the kinetics of COo-diethanol-amine reaction still admit room for speculation (28) and certain aspects of COo mass transfer in carbonate solutions have yet to be settled (2/,30). On the other hand, many complex schemes, mostly theoretical, have been analyzed successfully so that selectivities etc. can be predicted.
