Figure 3. Data of figure 2 after the application of linear normalization of equation 4. Classes are now clearly separated. It is worth noting the condensation of TEA data (class 4) in a very restricted region. Meaning of the classes HEX hexane PRN propanal ETH ethanol BEN benzene TEA triethylamine EDA ethylendiamine.

I, 4 in hydrocarbons to 2 in pyridine (3 - 11,0) and again decreases to 1,5 in alcohols. Calculated on this basis value 3 of coal increases droningly with increasing the content of carbon from 70 % till 87 % and in a case of more metamorphized coal is sharply decreased again. Data concerning to the extraction of Greta coal are evidence of maximal yield of extract (more than 20 %) under it treatment with ethylendiamine and dimethylformamide (3 -... 

Stability constants (ethylendiamine, glycinate, oxalate), surface complex formation constants and solubility products (sulfides) of transition ions. The surface complex formation constant is for the binding of metal ions to hydrous ferric oxide =Fe-OH + Me2+ =FeOMe++ H+ K. ... 

The reactants were ultrasonically dispersed in ethylendiamine, then transferred to a Teflon-lined autoclave and gradually heated up to 160°C. The products were filtered out, washed with absolute alcohol, normal HC1 solution and water and finally dried in vacuum. In the product nano-fibres and near single-crystal whiskers were obtained.

Clonidine Clonidine, 2-(2,6-dichlorophenylamino)imidazoline (11.1.34), is synthesized from 2,6-dichloroaniline, the reaction of which with ammonium thiocyante gives N-(2,6-dichlorophenyl)thiourea (11.1.32). Methylation of this product into (11.1.33) by the subsequent reaction with ethylendiamine gives clonidine (11.1.34) [34-39]. 

Naphazoline Naphazoline, 2-(l-naphthyhnethyl)-2-imidazoline (11.1.36), is synthesized from (l-naphthyl)acetonitrile, which upon reaction with ethanol transforms into imi-noester (11.1.35), and undergoes further heterocyclization into the desired imidozoline derivative (11.1.36) upon reaction with ethylendiamine [40]. 

OxymetazoUne Oxymetazoline, 6-fert-butyl-3 (2-imidazolin-2-ilmethyl)-2,4-dimethylphe-nol (11.1.39), is synthesized by chloromethylation of 6-tert-butyT2,4-dimethylphenol and the further transformation of the resulting chloromethyl derivative (11.1.37) into a nitrile (11.1.38). The reaction of this with ethylendiamine gives oxymetazoline (11.1.39) [41,42]. 

Xylometazoline Xylometazoline, 2-(4-fert-butyl-2,6-dimethylbenzyl)-2-imidazoline (11.1.40), is also synthesized in a single reaction by cyclocondensation of 4-fert-butyl-2,6-dimethylbenzylcyanide with ethylendiamine [43,44]. 

Tolazoline Tolazoline, 2-benzyl-2-imidazoline (12.2.7), is synthesized by the heterocy-clation of the ethyl ester of iminophenzylacetic acid with ethylendiamine (12.2.6), which forms the desired product (12.2.7) [32-35]. The structure of tolazoline is strikingly similar to a-adrenergic agonists, which are antiedema sympathomimetics. 

Die Oxidation von Aminen mit einem Gemisch aus Natrium-percarbonat (NPC) und Ethylendiamin-tetraessigsaure (EDTA) (Methode ) oder Peressigsaure (Methode ) fiihrt zur Nitroso-Verbindung, die durch Ozon zur Nitro-Verbindung oxidiert wird. So wird 1-Amino-adamantan in 94-95%iger Ausbeute zu 1-Nitro-adamantan oxidiert1 ... 

Other diamines besides ethylendiamine were employed in the course of this extensive investigation. Since most of the diamines selected are solids at room temperature they were reacted in solution or in the melt state (working at 75° C). The results can be summarized as follows ...

Substituted ureas were determined, at the beginning, by colorimetric analysis. This determination is based on a basic or acidic hydrolysis leading to the corresponding aniline, followed by diazotation and coupling with /V-(l-naphthyl)-ethylendiamine (40,58,148-152), 1-naphthol (153), or /V-ethy I-1 -naphthylamine (154) to obtain an azo-dye. Nevertheless, this method is time consuming and does not differentiate between the pesticide and metabolites, unless they are previously separated (154). 

Nitrate is reduced to nitrite (by cadmium reduction reaction), which is then determined by diazotization (pH = 2.0-2.5) with sulfanilamide and coupling N-( 1 -naphthyl)-1,2-ethylendiamine hydrochloride to form an intensely pink colored azo dye (540 nm) Brucine oxidation by nitrate ion in H2S04 at 100°C to form a yellow compound (cacoteline), which is measured at 410 nm...

Free chlorine reacts with N,N-( 1-naphthyl)-1,2-ethylendiamine hydrochloride (at pH 6.2-6.5) to form a red compound, which is titrated with a standardized solution of ammonium and ferrous sulfate until the red color of the solution disappears. 

Total chlorine is the sum of free and combined chlorine (defined as the residual chlorine existing in water in chemical combination with ammonia or organic amines). Total chlorine reacts with V,V-(l-naphthyl)-l,2-ethylendiamine hydrochloride and potassium iodide the compound formed is titrated as stated above.
