Novel method for synthetizing vinyl acetate by calcium carbide acetylene method

The invention relates to a novel method for synthetizing vinyl acetate by a calcium carbide acetylene method, which is characterized in that synthetic reaction is carried out on acetylene gas produced by adopting calcium carbide and acetic acid in a tube array type fixed bed reactor. The novel method is realized by utilizing a fixed bed technology in a process for synthetizing the vinyl acetate by the calcium carbide acetylene method, and especially, acetic acid simultaneously enters a gas-liquid mixed evaporator under the action of the acetylene gas after being preheated by changing an acetic acid feed mode into a gas-liquid mixed feed mode, and then enters the reactor through a second preheater and a third preheater, and the gas mixture passes through an inert heat transfer filler and then passes though a corresponding catalyst to be synthetized into the vinyl acetate. By adopting the mode, the novel method can reduce reaction byproducts and has the advantages of easy separation, raw material use ration improvement, production cost reduction, conversion rate improvement, small investment, high product purity, high quality and low impurity content.

Low-resilience highly air-permeable polyurethane foam and use thereof

A low-resilience highly air-permeable polyurethane foam is prepared by the foaming of a polyurethane raw material containing a polyol component, a polyisocyanate component, a catalyst, and a blowing agent, followed by removal of a foam skin (reticulation). This polyurethane foam has a glass transition point near room temperature and a cell number (cell count) of 25 PPI or less. The polyurethane foam has a large air bubble size as indicated by a cell number of 25 PPI or less. In addition, because the skin of the polyurethane foam is removed, it has high air permeability. Since the polyurethane foam comes into contact with human body at fewer points, unpleasantness, such as “stuffy” feeling, can be reduced. Since the polyurethane foam has large air bubbles, it exhibits excellent drainability and dries in a shorter time.
