                                              ALLYL ALCOHOL                       2.41
                    carbon dioxide and, after removal of the carbon dioxide, the unreacted
                    gases are recycled to the reactor.
                      In the second step, the hydrolysis, which is an equilibrium reaction of
                    allyl acetate, an acid catalyst is used and the reaction takes place at 60 to
                      o
                    80 C and allyl alcohol is selectively produced in almost 100 percent yield.
                    Acetic acid recovered from the hydrolysis process, is reused in the first
                    step.
                      Allyl alcohol forms an azeotropic mixture with water, and the mixture
                    is a homogeneous liquid. Therefore, to obtain dry allyl alcohol, ternary
                    azeotropic distillation and dehydration are required.
                      Allyl alcohol exhibits both bacterial and fungicidal effects and has been
                    used as such or as a source for derivatives with these effects.
