TL;DR: In this paper, the use of a supported catalyst for producing vinyl acetate from acetic acid, ethylene and oxygen, or gases containing oxygen, was described, and the supported catalyst contained palladium and or compounds thereof, gold and/or compounds thereof.
Abstract: The invention relates to a supported catalyst which contains palladium and/or compounds thereof, gold and/or compounds thereof, alkali metal compounds and also vanadium and/or compounds thereof. The invention also relates to the use of said supported catalyst for producing vinyl acetate from acetic acid, ethylene and oxygen, or gases containing oxygen.

TL;DR: In this paper, the effect of acetic acid vapour on pure cellulose paper using cold extraction pH and viscometric determination of the average degree of polymerization (DPv) of cellulose dissolved in cadoxen was investigated.
Abstract: Gas chromatography-mass spectrometry was used to analyse off-gassing from three archival boxes that had an acidic smell. A number of volatile organic compounds were found, including acetic (ethanoic) acid, likely to be generated by Jade 403, a poly (vinyl acetate/ethylene) adhesive that had been used in the boxes. The aim of this study was to assess the effect of acetic acid vapour on pure cellulose paper using cold extraction pH and viscometric determination of the average degree of polymerization (DPv) of cellulose dissolved in cadoxen. Whatman No. 1 paper samples were exposed to 200, 20 and 3mgm–3 of acetic acid vapour for 40 and 80 days. The degree of degradation both immediately after exposure and following artificial aging at 80°C and 65% RH for 30 and 60 days was significant in all samples except those exposed for 80 days at 3mgm–3. The results suggest that the effect of acetic acid on paper most likely occurs over the long term after the exposure. Concerns about acid-emitting materials bei...

15 Aug 1994TL;DR: In this article, a reusable and compostable coated paper stock comprising a substrate coated on at least one surface with a primer coat and a top coat both of which are water-based dispersions is described.
Abstract: Recyclable and compostable coated paper stock comprising a substrate coated on at least one surface with a primer coat and a top coat both of which are water based dispersions. The primer coat comprises a water based dispersion of a polymer selected from the group comprising acrylic polymers, acrylic copolymers, polyvinyl acetate, polyvinyl alcohol, poly-ethylene vinyl acetate, poly-ethylene vinyl chloride, styrene butadiene copolymers, polyvinylidiene chloride or starch. The top coat comprises a water based dispersion of a polymer selected from the group comprising acrylic polymers, acrylic copolymers, styrene butadiene copolymers or polyvinylidiene chloride. In another embodiment the top coat further includes a wax component comprising 15-90 wt. % of the polymer and 5-85 wt. % of the wax. The substrate is coated with a primer coat prior to the application of the top coat to seal the substrate surface. The top coat forms a film over the primer coat and imparts water and grease resistant properties to the coated paper stocks. The invention also includes processes for making and using the invented coated paper stocks.
