Boiling point 115.5 ℃ , refractive index 1.509 5, relative to density 0.981 9.
Analyse pure pyridine to contain a few moisture content, can use for general experiment. If want to make,get anhydrous pyridine, can change pyridine and bead oxyhydrogen potassium (sodium) together circumfluence, isolate next humidity evaporate goes out reserve. Dry pyridine water imbibition is very strong, it is good when saving to should seal container mouth should seal container mouth with olefin.
