    Hydrolysis of Vegetable Oils in Elevators Michael Johnson www.oilscrubber.com Vegetable Oil in hydraulic elevators has been met with mixed results, from no problems at all to destruction of the oil and system components. The unique environment and design characteristics of the hydraulic elevator are the causes of this variation in performance. Water or moisture is the natural enemy of the vegetable oils or technically Ester oil. [1]Hydrolysis is the reaction of an ester with water producing an alcohol plus and acid. In the case o...
