General description

Hydrogenation of 3-(dimethylamino)propionitrile over palladium catalysts has been investigated.

Application

3-(Dimethylamino)propionitrile has been used:
  • to initiate the organic polymerization during the synthesis of class I hybrid poly(N-isopropylacrylamide)/silica hydrogels
  • in preparation of cysteine modifying agents based on the solvatochromic fluorophore 4-N,N-dimethylamino-1,8-naphthalimide (4-DMN)
Catalyst similar to TEMED used to form oxygen free radicals from ammonium persulfate. Free radicals cause acrylamide and bis-acrylamide to polymerize.

The solvatochromic fluorophore 4-N,N-dimethylamino-1,8-naphthalimide (4-DMN) possesses extremely sensitive emission properties due largely to the low intrinsic fluorescence it exhibits in polar protic solvents such as water. This makes it well suited as a probe for the detection of a wide

Class I hybrid poly(N-isopropylacrylamide)/silica hydrogels, PNIPAM/SiO2, were prepared by a new one shot synthesis. In this approach, the free-radical polymerization of vinyl groups of N-isopropylacrylamide (NIPAM) and the hydrolysis-condensation of alkoxy groups of tetramethoxysilane (TMOS) are performed concomitantly using sodium

The toxicity of the mixture NIAX-ESN which contains 95% dimethylaminopropionitrile was evaluated in male rats. Large doses (2.0 ml/kg ip) rapidly produced CNS excitation followed by depression and death. The mixture (given orally as two doses of 0.31 or 0.62
