At the same time. a pyrolytic-TLC method has been established and applied to the analysis of benzodiazepines and other nitrogen containing drugs, the developing systems are:S_1:chloroform-ethyl acetate-n-butanol-concentrate ammonia (7∶3∶0.9∶0.05),S_2:carbon tetrachloride-ether-n-butanol-concentrate ammonia (7∶3∶1. 5∶0.03).
Study on the Synthesis, Characterization of New Type of Complex Pallidiunm Catalysts Supported on the Zirconium (Phosphonate-Phosphate) Containing N, P Ligands Coated on TiO_2 or ZrO_2 and Their Catalytic Property of Carbonylation
About 20% maximum N loss produced in the test process; this was related with the production of gaseous products containing N (N2, NO and N2O) due to coupling ammonia oxidation and anaerobic ammonia oxidation.
All agents are cytotoxic nitrogen mustard agents, a class of drugs widely used in the clinical treatment of cancer.
Discriminant analysis of the molecular properties of 17 nitrogen mustard agents designed in this work determined the extent of dissimilarity among members of this group.
An advantage of DNB is that it is suitable for the separation of the basic compounds containing nitrogen atoms without a capped process because the spacer containing nitrogen atoms can shield the residual silanols from DNB.
The gas used in this gas jet/electrostatic spinning was nitrogen.
The synthesis of high-nitrogen energetic material 3,3'-azobis (6-amino-1,2,4,5-tetrazine) (DAAT) from 3,6-bis (3,5-dimethylpyrazol-1-yl)-1,2,4,5-tetrazine by a four-step reaction is described.
If all operations are repeated periodically, the relative standard deviation of the retention times of nitrogen containing drugs in temperature programmed analysis will be 0.2% or less.
Several detectors which have a selective response toward nitrogen containing compounds are discussed.
Trace determination of amines and other nitrogen containing compounds with a modiefied thermal energy analyzer (TEATM)
For instance, for phosphorus containing compounds they are approximately the same (～102), while for nitrogen containing compounds in the case of carbon monoxide, there is a 2-5 fold increase in the response.
50% of 1500 ppm of ammonia could be removed from wastewater of pH 12 at 503 K under 2.0 MPa of air by using 4.0 g of catalyst without formation of toxic nitrogen containing compounds.
