NEW TRANSFORMATIONS OF VINYL ACETATE UNDER THE INFLUENCE OF THE COMPLEX Rh(PPh3)3Cl

The strictly regioselective hydrocarboxylation of vinyl acetate to ethylidene diacetate by acetic acid formed in situ from vinyl acetate was realized for the first time with Rh(PPh3)3Cl as catalyst.The transformation of vinyl acetate into benzene, acetophenone, and acetylene was also realized. Keywords: Hydrocarboxylation, vinyl acetate, metal complex catalyst.

Method for synthesizing vinyl acetate through methyl acetate carbonylation

The invention relates to a method for synthesizing vinyl acetate through methyl acetate carbonylation. When vinyl acetate is prepared from methyl acetate through the route of carbonylation and cracking, vinyl acetate yield and selectivity are low. The invention mainly aims at solving the problems. The method comprises the following steps: methyl acetate carbonylation is carried out, such that ethylene diacetate is obtained; and ethylene diacetate is cracked, such that vinyl acetate is obtained. A carbonylation catalyst adopts SiO2, Al2O3 or a mixture thereof as a carrier, and has active components comprising at least one selected from iron-series elements, at least one selected from metalloid elements and at least one metal element selected from IB and alkaline earth metals. With the technical scheme, the technical problem is well solved. The method can be used in industrial production of vinyl acetate.

Preparation of acetic acid

The disclosure relates to a process for the preparation of acetic acid. The process comprises reacting a decanter heavy, organic phase of an acetic acid production process with acetic anhydride to convert acetaldehyde in the decanter heavy, organic phase to ethylidene diacetate and separating it from the decanter heavy, organic phase. Ethylidene diacetate can be hydrolyzed to recover acetic acid.
