Preparation of N-substituted morpholine it Organic Compounds Technical Field The present invention relates to a process of preparing N-substituted morpholines it organic compounds. WOA1 en. Therefore only one-step reaction method of preparation of N- alkyl, substituted hydroxypropyl morpholine few compounds, do not have the versatility. Categories : Alkali metal iodides Inorganic compounds Iodides Ionising radiation detectors Metal halides Phosphors and scintillators Sodium compounds. Sodium iodide is used for conversion of alkyl chlorides into alkyl iodides. Main hazards.
Sodium iodide was added in small portions over a period of 2 min to a solution The filtrate was washed with 10% sodium thiosulfate (3 × 20 mL), water (2 × 20. One advantage of this system is that large NaI(Tl) crystals can be produced at.

this compound are about 10, times slower than those of 1-bromopropane. Sodium Iodide (Tl) - NaI(Tl) - is a well established and the most extensively used scintillator.
It is used for detecting gamma rays of low and intermediate energies. Sodium iodide (chemical formula NaI) is an ionic compound formed from the chemical reaction of sodium metal and iodine. Under standard conditions, it is a white, water-soluble solid comprising a mix of sodium cations (Na+) and iodide anions (I−) in a crystal lattice. 2 Solubility data; 3 See also; 4 References ; 5 External links.
