Amines ethylenediamine

Lithium Acetylide. Lithium acetyhde—ethylenediamine complex [50475-76-8], LiCM7H -112X01120112X112, is obtained as colodess-to-light-tan, free-flowing crystals from the reaction of /V-lithoethylenediamine and acetylene in an appropriate solvent (131). The complex decomposes slowly above 40°O to lithium carbide and ethylenediamine. Lithium acetyhde—ethylenediamine is very soluble in primary amines, ethylenediamine, and dimethyl sulfoxide. It is slightly soluble in ether, THF, and secondary and tertiary amines, and is insoluble in hydrocarbons. 

Unit cells of pure cellulose fall into five different classes, I—IV and x. This organization, with recent subclasses, is used here, but Cellulose x is not discussed because there has been no recent work on it. Crystalline complexes with alkaU (50), water (51), or amines (ethylenediamine, diaminopropane, and hydrazine) (52), and crystalline cellulose derivatives also exist. Those stmctures provide models for the interactions of various agents with cellulose, as well as additional information on the cellulose backbone itself. Usually, as shown in Eigure la, there are two residues in the repeated distance. However, in one of the alkah complexes (53), the backbone takes a three-fold hehcal shape. Nitrocellulose [9004-70-0] heUces have 2.5 residues per turn, with the repeat observed after two turns (54).

Amines are the particular products of putrefaction. None of the AF tested utilized amines (putrescine, ethylenediamine) as the sole source of nitrogen in culture (Table 4.1), although some amines (ethylenediamine, trimethyl-amine) are as effective as urea in the field (Sagara 1975,1992). This would show that AF do not directly utilize amines but utilize them only after decomposition to ammonia. Thus, the word postputrefaction in the term PPF may seem inappropriate from the fungal physiological point of view (Yamanaka 2002), but this word indicates the characteristic feature of cadaver and fecal decomposition. It also describes the major cause for growth of the AF in nature. 

C. Yield 21 grams, 73 per cent. It crystallises from methyl alcohol in microscopic needles, M.pt. 228° C. with decomposition, is insoluble in most organic solvents, slightly soluble iir methyl alcohol, but readily soluble in acids, ammonium hydroxide, amines, ethylenediamine, or pyridine. 

Another case involving cobalt complexes was studied by Work (19), who prepared, among others, a compound containing three different bidentate amines—ethylenediamine, trimethylene-diamine, and neopentanediamine, [Co(en)(tn)(dan)]CI3, by following and extending a synthesis first described by Werner (20) ... 

A modified uridine suitable for the post synthetic attachment of various amines has been described. The modified uridine (206) was utilised in oligonucleotide synthesis and reacted with lithium hydroxide, methanolic anunonia, ethanol-amine, ethylenediamine and 6-aminohexanol and 1,12-diaminododecane to yield of variety of modified oligonucleotides.

Extraction Rate and Agent Initially, the extraction process proceeds rapidly and becomes slow after a few hours (25). An extracting agent is effective if at 473 K the liquid is capable of dissolving 20 to 40% of a bituminous coal. Effective extracting agents are pyridine, picolines, aliphatic amines, ethylenediamine, phenol, cresol, o-phenylphenol, acetophenone, furfural etc. while benzene, trichloroethylene etc. are less effective. 

Epoxy resins of the bisphenol A type are synthesized from bisphenol A and epichlorhydrin. Hardeners, such as amines (ethylenediamine, diethylenetriamine, triethylenetetramine, isophoronediamine, triethy-lenetriamine and 4,4 -diaminophenylmethane) or acid anhydrides (phthalic anhydride) are added. Reactive diluents may be added, such as allyl glycidyl ether, butanediol diglycidyl ether, -butyl glycidyl ether, o-cresyl glycidyl ether, hexanediol diglycidyl ether. 

Aldehyde-sugars (glucose) and derived disaccharides of it (lactose) in solid form are, in contrast to the keto-sugars (fructose), incompatible with strongly alkaline compounds and primary amines (ethylenediamine). A brown discolouration (caramellisation) takes place. In the case of primary amines is this called the MaUlard reaction. In mixtures of solid (anhydrous) substances these reactions proceed very slowly and they occur only on the surface of the sugar particle. Thus they may be irrelevant in practice. However, because of this incompatibility the WHO formulation for the oral rehydration salts prescribes anhydrous glucose, which moreover is not combined with sodium bicarbonate but with sodium citrate. It is preferable not to use lactose in capsules with primary aliphatic amines. A more recently reported Maillard reaction is that between lactose and fluoxetine [30]. 

Both monodentate and bidentate amines form cationic complexes. Reactions of [MX(S2CNMe2)] (X = Cl, Br) with a wide range of amines has been carried out, the nature of the product being sensitive to the stoichiometry of the reaction. Neutral products, [MX(amine)(S2CNMe2)], are obtained when 1 equiv of amine is added, while cations, [M(amine)2(S2CNMe2)]X, result upon addition of 2-3 equiv. With the bidentate amines, ethylenediamine and 1,3-diaminopropane, cationic products [M(diamine)(S2CNMe2)]X always ensue (1609,1610).
