Talk:Glycerine

how to purification the glycerine obtained during the preparation of Biodiesel?

D-glycerol and L-glycerol: as glycerol is not optically active there is only one form. these names are therefore meaningless. Are they really used in practice? user:Evanherk

I don't know if the D-and L form are in use, but I added the not-optically active note. Ties 22:39, 19 Oct 2004 (UTC)
