Pyridine(110-86-1) is a polar, basic, low-reactive solvent, especially for dehydrochlorination reactions and extraction of antibiotics. In elimination reaction, pyridine acts as the base of the elimination reaction and bonds the resulting hydrogen halide to form a pyridinium salt. In esterification...

Ultrasound-Assisted Synthesis of Pyrazolo[3,4-b]pyridines as Potential Corrosion Inhibitors for Mild Steel in 1.0 M HCl Five synthesized pyrazolopyridine derivatives, such as 4-(2-chloro-6-flurpphenyl)-3-methyl-6-oxo-4,5,6,7-tetrahydro-2H-pyrazolo[3,4-b]-pyridine-5-carbonitr... A Dan...
A 25.0 mL sample of 0.100 M pyridine is titrated with 0.100 M hydrochloric acid. Calculate the pH after the addition of 26.0 mL of HCl.pH Value:The pH value of a solution beyond the equivalence point of the reaction can be calcul...
During dehydrochlorination there is no HCl evolution as it forms a pyridine hydrochloride complex which is supposed to act as a catalyst for dehydrochlorination. A possible mechanism has been proposed. Chain scission and cross-linking reactions are responsible for the molecular weight changes that ...
Diester 60 was then converted to lactam 63 in an elegant one-pot operation involving a Mannich/lactamization tandem reaction (60→61) followed by ester hydrolysis (NaOH), decarboxylation (HCl), and finally dynamic crystallization of the product 62 under mildly basic conditions (NaHCO3). In ...
On cooling, crystals of pyridine-HgCl2 (1:1) complex separated and were filtered off, crystallised from 1% HCl (to m 178.5-179o), washed with a little EtOH and dried at 110o. The free base was liberated by addition of excess aqueous NaOH and separated by steam distillation. The ...
HCl for each mol of 3-cyano-pyridine. The suspension is maintained at 10° to 15°C and stirred continuously while introducing a current of hydrogen at a pressure of 3 to 5 psi. When absorption of hydrogen ceases and the 3-cyanopyridine is completely reduced, the reaction mixture is ...
