Molecular formula: C4H10O; CH3 (CH2) 3OH Molecular Weight: 74.12 CAS Number: 71-36-3 vapor pressure: 0.82KPa / 25 ℃ Solubility: soluble in water, soluble in alcohol, ether, etc. Most organic solvents Stability: Appearance : colorless transparent liquid with special odor butanol manufacturers offer, people nausea hazard markers: 7 (flammable liquids) term S13Keep away from food safety butanol price quotes, drink and animal foodstuffs away from food, drink and animal feed preservation. S26In case of contact with eyes, rinse immediately with plenty of water and seek medical advice. After accidental contact with eyes, rinse immediately with plenty of water and seek medical advice. S37 / 39Wear suitable gloves and eye / face protection Wear suitable gloves and goggles or a mask. When using a cobalt catalyst, the reaction in 10 ~ 20MPa and about 130 ~ 160 ° C is carried out, n-butyl aldehyde and isobutyl aldehyde ratio of the rhodium complex catalyst produced approximately 3.1976 started in industrial applications, so that The reaction may be 0.7 ~ 3MPa and 80 ~ 120 ° C is carried out, n-butyl aldehyde and isobutyl aldehyde ratio of up to 8 to 16. Hydrogenation may be in the gas phase with a nickel or copper catalyst, in the liquid phase can also be used for the next nickel catalyst. If the hydrogenation at high pressure and temperature, the decomposition of some by-products may also be derived butanol, product purity can be improved. Aldol condensation method from two molecules of acetaldehyde Qilu Petrochemical butanol, after condensation and dehydration, crotonaldehyde can be obtained: n-butanol crotonaldehyde in the presence of nickel-chromium catalyst at 180 ° C and 0.2MPa hydrogenation of n-butyl alcohol. CH3CH = CHCHO + 2H2─ → CH3CH2CH2CH2OH in the above three methods, propylene oxo synthesis due to raw materials, hydroformylation process has been relatively lower pressure, the product of n-butanol and isobutanol, and can improve the ratio of cogeneration or specialized Production of 2-ethylhexanol, etc., have become the most important butanol production methods.
