Witryna1 lip 2024 · Abstract. Hygroscopic powders adsorb water from air humidity, increasing their cohesion and decreasing their flowability. Maltodextrin, pectin and starch powders were used to evaluate the correlation between flow factor and water content expressed both, as absolute moisture, and as water activity. Butanone, also known as methyl ethyl ketone (MEK), is an organic compound with the formula CH3C(O)CH2CH3. This colourless liquid ketone has a sharp, sweet odor reminiscent of acetone. It is produced industrially on a large scale, but occurs in nature only in trace amounts. It is partially soluble in water, … Zobacz więcej Butanone may be produced by oxidation of 2-butanol. The dehydrogenation of 2-butanol is catalysed by copper, zinc, or bronze: CH3CH(OH)CH2CH3 → CH3C(O)CH2CH3 … Zobacz więcej As a solvent Butanone is an effective and common solvent and is used in processes involving gums, resins, cellulose acetate and nitrocellulose coatings … Zobacz więcej • International Chemical Safety Card 0179 • National Pollutant Inventory: Methyl Ethyl Ketone Fact Sheet • NIOSH Pocket Guide to Chemical Hazards • US EPA Datasheet Zobacz więcej Flammability Butanone can react with most oxidizing materials, and can produce fires.
