Diamines with short aliphatic chains (ethylene diamine and 1,4-diamino butane) and a relatively high number of amine functionalities (tetraethylenepentamine) were chosen so that polymerization would occur at lower temperatures to produce PBzs with improved thermal stability.
It is worth noting that extraction of [Co.sup.2+] and [Ni.sup.2+] from the aqueous phase containing ethylene diamine was suppressed (Ex% = 0).
Chelation, on the other hand, uses EDTA (ethylene diamine tetra acetic acid) made of amino acids that are the building blocks of proteins, to leach out metabolically active calcium embedded in the arterial walls.

The chemicals used in the modification of the electrode such as copper sulfate 5-hydrate, ethylene diamine tetra acetic acid, hydrochloric acid 37%, tin chloride, sodium hydroxide, Palladium (EE) chloride, formaldehyde 36% and all materials used in making the medium needed to growth microorganisms were obtained from Merck, Germany.
Summary: A novel heterocyclic amine derivatives, namely N, N'- substituted pyridinyl ethylene diamine tetra acetic acid sodium salt {A} and ethylene diamine N, N'-diacetic acid di (2-methylene tetra hydro furfuryl) acetate {B} were synthesized and their structure confirmations were performed by FTIR, 1HNMR and 13CNMR spectra.
Covered are sodium tripolyphosphate (STPP), phosphonates (ATMP, EDTMP, DTPMP, HEDP, PBTC, and HDTMP), ethylene diamine tetra acetic acid (EDTA), nitrilotriacetic acid (NTA), diethylene triamine pentaacetic acid (DTPA) and other products (citric acid, GLDA, MGDA, EDDS, IDS, GA, PDTA, HEDTA, glucoheptonates).
Methyl Methacrylate (MMA) was purchased fromACROS (USA), Potassium Persulfate ([K.sub.2][S.sub.2][O.sub.8]), Ethylene Diamine (EDA) and [alpha]-Galactosidase from Aspergillus oryzae (E.C. were obtained from Siga Chem.
Other minor uses of VCM include manufacture of ethylene diamine for the production of resins and manufacture of chlorinated solvents.
A wide variety of treatments for dermatophytosis have been used in cattle including chlorhexidine, salicylic acid (2 to 5 percent), iodine containing shampoos and tinctures, griseofulvin (Rochette et al., 2003, Radostits et al., 2007), thiabendazole (Gabal 1986) and ethylene diamine dihydroiodide (Qam et al., 2007) and vaccination against Trichophyton verrucosum for preventing disease (Radostits et al., 2007).
The main ingredients of such products are paraphenylene diamine (PPD), resorcinol, propylene glycol, sodium ethylene diamine tetra acetic acid (EDTA), preservatives, and perfumes.
