Properties and stability

1. Stable and easy to polymerize into dimers. In addition to having hydroxyl and carbonyl properties, it is also easily oxidized by cuprous oxide and forms uracil with phenylhydrazine. Avoid contact with strong oxidants and moisture. Flammable and easy to absorb moisture. Avoid inhalation of vapor and smoke when using, and avoid contact with eyes and skin.

2. It is flammable and easy to absorb moisture. When using, avoid inhaling the vapor and smoke of this product, and avoid contact with eyes and skin.

3. Exist in flue-cured tobacco leaves, burley tobacco leaves, oriental tobacco leaves, and mainstream smoke.

4. Found in beer and honey.

Storage method

1. Store in a cool, ventilated warehouse. Store at 0-4ºC. Keep away from fire, heat and water sources. The packaging is sealed. should be kept away from oxidizer, do not store together. Equipped with the appropriate variety and quantity of fire equipment. Suitable materials should be available in the storage area to contain spills.

Synthesis method

1. It is produced by catalytic dehydrogenation of propylene glycol or the reaction of bromoacetone and potassium formate to form acetol formate, which is then hydrolyzed. It can also be obtained by catalytic dehydrogenation of glycerol or propylene glycol.

2.Carry out rectification, ultra-clean filtration, and ultra-clean packaging of industrial butanone to obtain BV-III grade butanone.

3. Preparation method:

In a reaction bottle equipped with a stirrer and reflux condenser, add 500 mL of methanol (water content <0.2%), slowly add 110 g (1.2 mol) of potassium formate while stirring, stir thoroughly and add Make it dissolve. After cooling, slowly add brominated acetone (2) 140g (1mol), and KBr precipitates soon. Reflux reaction for 15h. Cool in an ice-salt bath, filter out the potassium bromide, fractionate and reflux methanol and methyl formate, and then fractionate under reduced pressure to collect the 30-40°C/5-1.6kPa fraction to obtain hydroxyacetone (1 )17g, yield 45%. Note: ① Bromoacetone has strong tear-inducing and irritating effects, so special attention should be paid when using it. ②Hydroxyacetone is unstable and easy to polymerize, but it is easy to prepare 50% methanol and can last for more than one year.

1. Used to prepare drugs, spices, dyes, etc. Methanol can be added as a stabilizer during storage. Organic synthesis intermediates, solvents for nitrocellulose, and protective agents for peptide synthesis.

2.Electronic pure ethyl ketone is used as a developer and cleaning agent in the photolithography process of integrated circuits in the electronic industry. MOS level is mainly used for discrete devices and large and medium-scale integrated circuits, and BV-III level is mainly used for the production of very large-scale integrated circuits.
