The hydrolyses of ADP and ATP were tried in the presence of low-molecular-weight analogs of polyethylenimine, i e. ethylenediamine, 77 (ED), diethylenetriamine, 78 (DT), triethylenetetramine, 79 (TT), tetraethylenepentamine, 80 (TP) and pentaethylenehexamine129). These compounds accelerated the reaction several times. The degree of the acceleration increased with increasing degree of polymerization. 

An amido-amine (e.g., from the reaction of tetraethylenepentamine with stearic acid) is modified with propylene oxide [792]. The product is dispersed in a polymer matrix such as an acrylic or methacrylic polymer. The inhibitor is slowly released into the surrounding environment, such as in an oil or gas well, to prevent corrosion of metal equipment in the well. 

Several studies have been dedicated to the application of amine-modified carbon nano tubes (CNTs) as solid sorbents for C02 separation [65-69]. Industrial grade CNTs have been functionalized with tetraethylenepentamine (TEPA) by Liu et al. [65], and the effects of amine loadings on the C02 uptake, heat of adsorption, and adsorbent regenerability were investi-...

Kinetics and mechanisms of complex formation have been reviewed, with particular attention to the inherent Fe +aq + L vs. FeOH +aq + HL proton ambiguity. Table 11 contains a selection of rate constants and activation volumes for complex formation reactions from Fe " "aq and from FeOH +aq, illustrating the mechanistic difference between 4 for the former and 4 for the latter. Further kinetic details and discussion may be obtained from earlier publications and from those on reaction with azide, with cysteine, " with octane-and nonane-2,4-diones, with 2-acetylcyclopentanone, with fulvic acid, and with acethydroxamate and with desferrioxamine. For the last two systems the various component forward and reverse reactions were studied, with values given for k and K A/7 and A5, A/7° and A5 ° AF and AF°. Activation volumes are reported and consequences of the proton ambiguity discussed in relation to the reaction with azide. For the reactions of FeOH " aq with the salicylate and oxalate complexes d5-[Co(en)2(NH3)(sal)] ", [Co(tetraen)(sal)] " (tetraen = tetraethylenepentamine), and [Co(NH3)5(C204H)] both formation and dissociation are retarded in anionic micelles.
