The important indicator used for non aqueous titration are follow
1 crystal voilet it is used as 0.5%solution in glacial acetic acid it gives voile colour in basic medium and yellowish green in acidic medium. it is most widely use for the titration of pyridine with prechlorid acid
Hope it's help it

non aqueous titration.
non aqueous titrations are the titrations in which weakly acidic or basic substance are carried out using non aqueous solvent to get sharp end point.
the moisture content in non aqueous titrations should not be more than 0.05%.moisutre and carbon dioxide are to be avoided in non aqueous methods .
indicators used in non aqueous titration.
Crystal Violet.
0.5% w/v solution in glacial acetic acid .
colour change .violet to greenish yellow.
Methyl red.
0.2% w/v solution in di oxane
colour change yellow to red .
Thymol blue
0.2% w/v Thymole
colour change yellow to blue.
