In the related links box below, I posted the wikipedia article on pyridine acid.
i do not have the answer
what is the reaction mechanism between acrylic acid,4-vinyl pyridine
This is pyridine a very weak base
The vitamin B3 is nicotinic acid (or more correct pyridine-3-carboxylic acid) with the chemical formula C6H5NO2.
Pyridine is a basic organic aromtic compound it contains nitrogen in ring which has a lone pair of electrons, when sulphuric acid is added a salt is formed which may be either Pyridinium sulphate or Pyridinium hydrogen sulphate depending upon the ratio of two compounds mixed.

Niacin is the nicotonic acid or pyridine-3-carboxylic acid (after correct IUPAC rules) - C6H4NO2.

Bases containing the pyridine substructure, or derived from pyridine as a starting material. Pyridine is basically benzene with one of the carbons substituted with a nitrogen, if that helps.
The most convenient ways often involve complexing the pyridine with other molecules. this will change the chemical proporties of both, easing extraction. One method is co-evaporating the pyridine off with toluene. Adding Toluene in a 1:1 ratio will form a complex with a lower boiling point, taking both the pyridine and toluene out of the mixture. Another method is complexing the pyridine with CuSO4. This is done by washing the reaction mixture with a saturated aqueous CuSO4 solution and then separating the layers. The pyridine will remain in the aqueous layer with the CuSO4. Keep in mind that these, and most other similar processes (like acid washes) will only remove free pyridine, and that some pyridine may be left behind in complexes with your product (salts).
Yes Pyridine is a tertiary amine.
NaCl is not soluble in pyridine.
because pyridine is toxic...so amines are used in place of pyridine.......
