Is nitrobenzene soluble in water?
- Nitrobenzene is a nitro aromatic compound that exists at room tem- perature as a greenish-yellow or yellow oily liquid with the odor of bitter almonds. It is slightly soluble in water, soluble in acetone, and freely soluble in alcohol, benzene, ether, and oils.
What pKa is a buffer?
- A buffer is effective at ± one pH units from the pK of the buffering ion, giving some flexibility in optimizing the mobile phase. Acetate, for example, has a pKa of 4.8 and buffers from pH 3.8 to 5.8. Formate is more acidic and buffers from pH 2.8 to 4.8. There are additional buffer choices if acidic analytes would be not be ionizable at lower pH.
What does nitrobenzene smell like?
- CHEMICAL AND PHYSICAL INFORMATION Nitrobenzene is a colorless to pale yellow oily liquid composed of a benzene ring with a single substituted nitro group. The compound is a synthetic chemical, and it does not occur naturally. It has an odor similar to bitter almonds or shoe polish.
What is nitrobenzene used for?
- Most nitrobenzene (97%) is used in the manufacture of aniline (IARC 1996, HSDB 2009). Miscellaneous uses include the manufacture of benzidine, quinoline, azobenzene, pyroxylin compounds, isocya- nates, pesticides, rubber chemicals, pharmaceuticals, and dyes such as nigrosines and magenta.
