2-Ethylhexanol -Properties

Colorless transparent flammable liquid with special smell. Soluble in about 720 times of water, miscible with most organic solvents. In case of high heat, open flame or contact with oxidant, there is a danger of combustion. In case of high heat, the internal pressure of the container increases, and there is a risk of cracking and explosion. It can form explosive mixtures with air. Can accumulate static electricity and ignite its vapor.

2-ethylhexanol -preparation

 

acetaldehyde condensation method is to first generate butanol aldehyde by condensation of two molecules of ethanol, and then dehydrate to generate crotonaldehyde (crotonaldehyde), which is hydrogenated to obtain n-butyraldehyde; n-butyraldehyde is hydrogenated to obtain n-butanol; If condensation dehydration is used to generate 2-ethyl hexenal, and further hydrogenation is used to obtain the final product 2-ethyl hexanol. Or the high-pressure carbonyl synthesis method is used to synthesize n-butyraldehyde and isobutyraldehyde with propylene, carbon monoxide and hydrogen as raw materials and tetracarbonyl hydrogen cobalt as catalyst. The hydrogenation of n-butyraldehyde and isobutyraldehyde was carried out using copper or nickel as catalyst. n-Butyraldehyde is hydrogenated in gas phase or solid phase to produce n-butanol; after preliminary distillation, n-butanol is purified in a two-tower distillation system. Using sodium hydroxide as catalyst for n-butanol condensation and dehydration of 2 ethyl hexenal. 2 ethylhexenal hydrogenation in the presence of nickel catalyst, under a certain temperature and pressure hydrogenation of iso 2 ethyl hexanol.

2-Ethylhexanol -Application

 

is used as a defoamer for drilling fluids. Also used in the preparation of phthalate dioctyl ester, azelaic acid dioctyl cheese and other plasticizers.

2-Ethylhexanol -Safety

 

Rat oral LD50: 12.46 mL/kg. Ingestion, inhalation or absorption through the skin after harmful to the body, can cause skin allergic reactions. Strong irritation to the eyes, eye contact with this product, can damage the eyes; stored in a cool, ventilated warehouse. Keep away from fire and heat source. Prevent direct sunlight.
