摘要： A Process for making vinyl acetate, comprising the steps:
(a) providing hydrogen with a deuterium content below 90 ppm, based on the total hydrogen content, by water electrolysis using electrical power that is generated at least in part from non-fossil, renewable resources;
(b) providing carbon dioxide;
(c) reacting hydrogen and carbon dioxide in the presence of a catalyst to form methanol with a deuterium content below 90 ppm, based on the total hydrogen content;
(d) reacting methanol from step (c) to form ethylene; and
(e) reacting methanol from step (c) with carbon monoxide to form acetic acid; and/or
(f1) reacting part of the ethylene from step (d) with oxygen and water to give acetaldehyde;
(f2) reacting acetaldehyde from step (f1) with oxygen to give acetic acid;
(g) reacting acetic acid from step (e) and/or step (f1) with ethylene from step (d) to give vinyl acetate.-

摘要： A method for synthesizing a labeled pyruvic acid is provided. An isopropenyl Grignard reagent is added to a reaction vessel and cooled to a preset temperature. A carbon isotope-labeled carbon dioxide is added to the reaction vessel and continuously reacted with the isopropenyl Grignard reagent for a preset time. The reaction system is added with an acid and adjusted to a preset temperature to quench the reaction. The reaction system is subjected to ozonization, and reduced in the presence of a reducing agent. Impurities are removed to obtain the labeled pyruvic acid.
