Abstract: The present invention relates to a process for forming vinyl acetate. The process comprises the step of providing a reaction mixture having an initial heat capacity. The reaction mixture comprises acetic acid, oxygen, ethylene, and optionally water. The process further comprises the step of adding to the reaction mixture at least one heat capacity modifier to form an increased heat capacity reaction mixture. The process further comprises the step of contacting the acetic acid, oxygen, and ethylene over a catalyst under conditions effective to form a crude vinyl acetate product. The crude vinyl acetate product comprises vinyl acetate and water.

Abstract: Shaving apparatus having at least one pivotable cutting unit (3) comprising an external cutting member (4) and an internal cutting member (6) which is drivable relative to said external cutting member, a drive mechanism (8) for driving said internal cutting member (6) into rotation, and a coupling member (18) having a coupling head (19) and a coupling body (20), which coupling head can be coupled to a coupling element (16) of the internal cutting member (6) in a detachable manner, said coupling body (20) being coupled to said driving mechanism (8). The coupling head (19) can be inserted into a cavity (21) of the coupling head (19). For driving said internal cutting member into rotation, the coupling head (19) comprises curved surfaces (25) for cooperation with surfaces (28) of said cavity (21).
