PRODUCT RANGE

2-Butanone
2-Butanone is an organic compound with a chemical formula of CH3COCH2CH3 and a molecular weight of 72.11. For colorless transparent liquid, there is a scent similarity. volatile. Can mix with ethanol, ether, benzene, chloroform, and oil. Soluble in 4 parts of water, but when the temperature rises, the solubility is reduced, which can form a co -boiling mixture with water. Low toxic, half of the death (mice, meridian) 3300mg/kg. Flammable, steam can form an explosive mixture with air. High -concentration vapor is anesthesia.

Chemistry properties

Methalisone is prone to various reactions due to the lively hydrogen adjacent to the cymbal group. Heated with hydrochloric acid or sodium hydroxide, which occurred together,and generated 3,4-diexyl-3-hexiene-2-ketone or 3-methyl-3-gallene-5-ketone. When it is irradiated by sunlight for a long time, ethylene, acetic acid, and contraction products are generated. Use linked acetyls when oxidized with nitrate. Acetic acid is generated when oxidized with a strong oxidation agent such as chromic acid. Antone is relatively stable at the heat, and at a higher temperature, the heat fissure is generated to generate hypenne or methylne ketone. When contralating with aliphed or aromatic aldarin, the ketone, ring -shaped compound, ketone, and resin of high molecular weight are generated. For example, with the existence of formaldehyde in the existence of sodium hydroxide, it is first generated to generate 2-gyx-1-butanol-3-ketone, and then dehydrated to form methyl heterolytone.
