| abstract | Tixocortol pivalate is manufactured on an industrial scale by forming a sodium salt to thiopivalic acid in a closed reaction vessel 1. The sodium salt is then reacted with an appropriate hydrocortisone derivative to form the pivalate. The thiopivalic acid is charged through an inlet line 4 into a container 2 which is housed in an enclosed fume tent 15 with a sealable entry door flap 14 and an outlet 16 to a scrubber. The inlet line 4 is then closed and a vacuum is drawn on the line 5 and a delivery line 20 from the reaction vessel 1. A valve 8 is then opened and the acid is drawn into the vessel 1. When the container 2 is emptied, acetone is used to wash any residual acid and the wash is also drawn into the vessel 1, cleaning the delivery line 20. |
