Di-n-propylamine

Di-n-propylamine is a colorless liquid, soluble in ethyl alcohol, methyl alcohol, ethyl ether, ethyl ocetate, acetone, paraffin hydrocorbons, aliphatic and aromotic hydrocarbons, fixed oils, mineral oil, oleic ond stearic acids. It dissolves hot paraffin ond carnauba waxcis which solidify when cooled. It is partly soluble in water. [Pg.691]

This water-white, primary aliphatic amine is available commercially in an anhydrous form. It is soluble In water, methyl and ethyl alcohols, ethyl ether, ethyl acetate, aromatic and aliphatic hydrocarbons, acetone, mineral oil, fixed oils, oleic and stearic acids. It is soluble In hat paraffin and carnouba waxes, which solidify on cooling. It is potentially useful os on intermediate In such manufactured products as dyestuffs, surface-active agents, textile specialties, pharmaceuticals, bactericides, insecticides, and cleaning compounds. It is also used os o dehoiring ogent in the leather industry. [Pg.692]

Analogous products are obtained if 2-fury lmethylamine, di-n-propylamine, or -(1,5-dimethyl)hexylamine are used instead of NH3, with yields of 67, 88 and 84%, respectively. [Pg.121]

A number of amidines have anthelmintic activity. Bunamidine (25), indicated for treatment of human pinworm infestations, is prepared from a-naphthylhexyl-ether (23) by Friedel-Crafts type reaction with cyanogen bromide and aluminum chloride to give nitrile (24). This, then, is reacted with the magnesium bromide salt of di-n-propylamine leading to the naph-thamidine structure (25). -... [Pg.212]

An EPA method was created for measuring NDMA and six additional nitrosamines in drinking water (EPA Method 521) [55]. This method uses GC/ chemical ionization (CI)-MS/MS and enables the measurement of NDMA and six other nitrosamines (N-nitrosomethylethylamine, N-nitrosodiethylamine, N-nitroso-di-n-propylamine, N-nitroso-di- -butylamine, N-nitrosopyrrolidine, and N-nitrosopiperidine) in drinking water at detection limits ranging fi om 1.2 to 2.1 ng/L. A liquid chromatography (LC)/MS/MS method [56] can also be used to measure nine nitrosamines, including N-nitrosodiphenylamine, which is thermally unstable and cannot be measured using the EPA Method. [Pg.104]

N-nitrosamines are a group of compounds characterized by a nitroso group (N=0) attached to the nitrogen of an aromatic or aliphatic secondary amine. N-nitrosodi-N-propylamine is a suspected reaction byproduct from the nitrosation of di-N-propylamine. Two pesticides are suspected to contain some form of nitrosamines. [Pg.515]

NCA polymerization by secondary amines may involve the amine or activated monomer mechanisms or both mechanisms simultaneously. Unhindered secondary amines such as dimethylamine and piperidine react like primary amines, and polymerization occurs by the amine mechanism. Polymerization by slightly hindered amines such as diethylamine, N-methylbenzylamine, and di-n-propylamine involves a combination of the amine and activated monomer mechanisms. More hindered secondary amines, such as di-n-isopropylamine and dicyclohexylamine, react almost exclusively via the activated monomer mechanism. [Pg.579]

Like the oxa method for naming ethers (Problem 14.61), the aza method is used for amines. Di-n-propylamine, CH3CH2CH2NHCH2CH2CH3, is 4-azaheptane and piperidine is azacyclohexane. The four H s of NH can be replaced to give a quaternary (4°) tetraalkyl (tetraaryl) ammonium... [Pg.412]
