title: Dehydration of tetracycline.
abstract: The dehydration of tetracycline at the C-5a-C-6 position as a function of acidity was investigated at various temperatures. The rate was first order with respect to tetracycline and with respect to [H+]. Rate constants and an activation energy are reported. Tetracycline was unstable in dilute acid.
