Triethylamine physical properties

Physical Properties, (i) Triethylamine, b.p. 90 , tri-n-propylamine, b.p. 156 , tri biitylamine, b.p. 212 ", are liquids with a fishy odour, and with decreasing solubility in water. 

Several physical properties of amorphous poly-DSP films have been measured64). For the preparation of amorphous films, a trifluoroacetic acid solution containing 10% poly-DSP is cast on a glass plate and dried in vacuo. The resulting film is extracted with triethylamine to remove the last traces of the acid and then extracted with ethanol. 

SYSTEM TRIETHYLAMINE-WATER, THE EQUILIBRIUM DIAGRAM AND SOME PHYSICAL PROPERTIES. 

Physical Properties.—The pXa values of 2-methyl- and 2-phenyl-2-thiazoline, determined potentiometrically, are 5.37 and 4.00, respectively. The optical stability of 2-thiazolines of type (203) has been estimated by measuring their rate of racemization in O.IN methanolic triethylamine. 2-Methyl-L-4-carboxymethyl-2-thiazoline (203 R = Me) is more stable... 

Tables 10.2 and 10.3 lists the physical properties of the aliphatic amines. The lowest molecular weight amine, ethylamine, boils at only 16.6 C and is thus available only as a compressed gas or as an aqueous solution. The other fifteen aliphatic amines have boiling points in the range of 32.4-213 C. The flash points of these amines are low with the highest being only 70 F for the tributylamine. These short-chain amines are readily soluble in water and most organic solvents. The solubility of amines decreases with increasing temperature, for example, triethylamine is completely soluble in water below 18 C but is only partially soluble above this temperature. The lower alkylamines have the characteristic ammonia odor which decreases with increased substitution onto the nitrogen atom.
