Definition
Dodecylamine is a solid white odor ammoniacal melting at a temperature between 27 and 31 ° C .
In liquid state, dodecylamine has a yellow color and an oily appearance, dodecylamin's boiling point being 259 ° C.
1-Dodecanamine appears as a yellow liquid with an ammonia-like odor.
Lauryl Amine is insoluble in water and less dense than water.
Hence floats on water.
Contact may irritate skin, eyes and mucous membranes.
1-Dodecanamine may be toxic by ingestion, inhalation or skin absorption. Used to make other chemicals.
Dodecylamine is crystalline colourless.
Intercalation of dodecylamine into the layer space of kaolinite was investigated.
Dodecylamine was investigated as inhibitor of mild steel hydrochloric acid corrosion.
Uses
Dodecylamine was used in preparation of novel surfactant copper(II) complexes.
1-Dodecanamine is used as a catalyst and template agent in the sol-gel process for the fabrication of monodispersed mesoporous bioactive glass sub-micron spheres.
Lauryl Amine is not a dangerous good if item is equal to or less than 1g/ml and there is less than 100g/ml in the package.
Dodecylamine spontaneously adsorbs on carbon steel via its polar group (-NH2) in hydrochloric acid solution.
Furthermore, 1-Dodecanamine forms a monolayer film on carbon steel surface.
The inhibition mechanism of dodecylamine for carbon steel is geometric blocking effect.
Lauryl Amine is often used as chemical reagent and as an organic intermediary in pharmaceutical research and development.
Synthesis and uses
Dodecylamine can be synthesized , with a yield close to 97%, by reduction of 1-azidododecane .
Dodecylamine has numerous uses as a solvent or catalyst .
Dodecylamine is used as a catalyst in sol-gel processes for the manufacture of bioactive mesoporous submicron glass spheres , or in the preparation of silica nanoparticles of adjustable size, with water being the reagent and different primary amines acting - such as 1-octaamine or dodecylamine - as catalysts.
Also Laurylamine can effect the synthesis of nanocrystals of cadmium selenide (CdSe) -of identical structure as sphalerite-, using 1-dodecanamine as a solvent.
On the other hand, dodecylamine has been used in the preparation of new copper (II) complexes with surfactant properties .
Laurylamine has also been used in the post-synthesis of mesoporous silica with the ability to remove heavy metals
