All chemicals were purchased from Sigma Aldrich and used without modification or cleaning, unless otherwise stated. N,N,N′,N′-tetrakis(2-hydroxypropyl)ethylenediamine (HPED, 99%), triethanolamine (TEA, 98%, Alfa Aesar), and 2,2,4-trimethyl hexamethylene diisocyanate (TMHDI, TCI America, a mixture of 2,2,4 and 2,4,4 monomers) were used as monomers. Ethyl isocyanate (98%, Sigma) was used for confirming urethane syntheformation. Fluorescent monomers, shown in Figure 1, PhB (99%), Eos (99%), IcG (95%), and Cal (99%) (Chem-Impex Int’l Inc.) were identified as having functional groups that react with isocyanate groups similarly to alcohol groups, and were added without modification. All reactive monomers are shown in Figure 1. The additives barium sulphate (BaSO4, particle size of 3 μm, 99%), zirconium oxide (ZrO2, particle size of 5 μm, 99%), and tungsten (W, particle size > 1 μm, 99.95%, Alfa Aesar) were used without modification.

Purification and Characterization of IPETC

Check if the same lab product or an alternative is used in the 5 most similar protocols
IPETC sample was a technical product (Tieling Flotation Reagents, Tieling city, Liaoning, China). Its purity was tested by 1H-NMR and GC and was established to be pure enough (less than 2% of impurities) to be used in the present study. Acetonitrile, dichloromethane, ethyl isocyanate (Aldrich) isopropanol, formic acid (Fluka), iron(III) chloride hexahydrate, iron(II) sulfate heptahydrate, sodium sulfite (Merck), hydrogen peroxide, 65% (Belinka, Ljubljana) were used without further purification. The concentration of sodium hypochlorite solution (Aldrich) was determined by iodometric titration prior to use. Deionized water was obtained from Millipore Milli-Q water system (Burlington, MA, USA).

Copper(II) carboxylate compounds with tert-butylamine of the general formula [Cu2(t-BuNH2)2(µ-O2CR)4], where R = CnF2n+1, n = 1–6, were obtained in the reaction of copper(II) perfluorinated carboxylates with tert-butylamine, which was in situ generated from tert-butyl isocyanate [34 (link)]:
The analogues procedure was applied for the synthesis of new complexes [Cu2(EtNH2)2(μ-O2CC2F5)4] and [Cu2(s-BuNH2)2(μ-O2CC2F5)4].
Copper(II) carboxylate [Cu(O2CC2F5)2] was prepared as reported [58 (link)]. Ethyl isocyanate (98%), sec-butyl isocyanate (s-BuNCO, 98%), and acetonitrile (99.93%) were purchased from Aldrich. All reagents were used as received.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
