The kinetics of the reactions of the primary and secondary amine groups in aqueous DETA solution were measured in a string of discs contactor at different concentrations and temperatures. The reaction rates of the primary amine group were performed at very low loading and for the secondary amine ...
Using Bullet Points ( • ) 'Gray' vs. 'Grey': What is the difference? Why is '-ed' sometimes pronounced at the end of a word? What's the difference between 'fascism' and 'socialism'? Popular in Wordplay See All Terroir, Oenophile, & Magnum: Ten Words About Wine ...
PURPOSE: To provide the subject specific polyethers which are useful for the manufacture of polyurethane or an epoxy resin by reacting polyether alcohols containing a specific OH group with either of NH and a primary or secondary amine in the presence of H, a reductive aminating catalyst at a...
Primary and secondary amino groups react very fast (2min) with FMOC, in slightly alkaline solution, to give the corresponding fluorescent 9-fluorenylmethyl carbamates, which exhibit high stability [84] (48h, at room temperature) and very sensitive fluorescence detectability. The disadvantages of thi...
