Hello, could anyone help..It's connected with cationc fat as product of oxyethyling of ethylendiamine with condencing it by acids of sunflower oil:
HO-H2C-H2C^-N-CH2-CH2-N^CH2-CH-OH +R-COOH -> HO-H2C-H2C-^N-CH2-CH2-N^H
-H -H -RCO -CH2-CH-OH
How is possible to find out what compound has formed when while investigating of it's content there were found such features :after extracting of surfactants by hexane (25%) under 20 C, there was found a sediment ( white and crumbly, density about 131 kg/m^3). Using organic solvents we've found that- this sediment were
solvent:
Octane - not soluble
Benzene -not soluble
Toluene-not soluble
o-Xylene - not soluble
Chloroform -soluble
four chloride carbone - not soluble
Acetone - soluble under T=50 -> T=20 falls sediments
Ethylacetat - soluble under T=50 ->T=20 C part.sediments
dioxane-1, 4 - soluble under T=50 -> T=22 part.sediments
isopropanol - soluble (T=20-50)
dimethylformamide - soluble under T=50 -> dissoc. under T=20
Diesel fuel - not soluble
Distillated water -not soluble
NaOH (5% rn) not soluble (T=20C) , dissoc. T=50
HCl (rozv. 1:1) not soluble (T=20), dissoc. T=50
SaCl2-10% sol.- not soluble.
This sediment has % wt of ^ C=60,4, H=11,5, N=15.3, P=1.0 ...
and now we're searching for a way and methodics how to find - what is the structure of sediment ( what kind of compund would it be)? Could anyone help me? PLEASE=)

Stallia,
Waht does the up arrow signify in your equation?
HO-H2C-H2C^-N-CH2-CH2-N^CH2-CH-OH +R-COOH -> HO-H2C-H2C-^N-CH2-CH2-N^H
-H -H -RCO -CH2-CH-OH
