What is 1-Propanol?

Propanol is a compound in which one hydrogen atom in the lp molecule is changed by a hydroxyl group. Due to the fact that the hydroxyl group can change the hydrogen at both ends of the carbon chain or the middle carbon atom, it can generate two isomers 1-Propanol and also isopropanol.

The chemical properties of 1-Propanol resemble those of ethanol. It is a colorless transparent fluid with a scent at area temperature level as well as typical pressure. It is generated industrially by ethylene, carbon monoxide gas and also hydrogen under high pressure and also cobalt catalysis, by hydration of propylene under the activity of sulfuric acid or by catalytic hydrogenation of acetone, as well as is usually used as a solvent. It is bothersome to eyes as well as mucous membranes. Breathing of propanol vapor can create dizziness, frustration and throwing up.

1-Propanol Uses

  1. 1-Propanol is typically used as a solvent, as well as is also a basic material for the prep work of n-propylamine and so on.
  2. 1-Propanol is utilized as a chromatographic reagent, solvent as well as cleaning agent.
  3. 1-Propanol is utilized as an extraction solvent; GB 27601996: Food flavors and also food processing aids.
  4. 1-Propanol is made use of as a solvent as well as in a lot of cases can replace ethanol which has a lower boiling point.
  5. 1-Propanol is used as a solvent as well as cleaner for veggie oils, natural rubber, resins as well as cellulose esters. Organic Synthesis. Gas Chromatographic Evaluation Criteria.
  6. 1-Propanol is directly utilized as a solvent or manufactured propyl acetate, used in paint solvents, printing inks, cosmetics, etc, made use of in the production of n-propylamine as an intermediate in medication and also pesticides, utilized in the production of feed additives, synthetic flavors, and so on.by-products of n-propanol, specifically di-n-propylamine, have lots of applications in the manufacturing of medicine and chemicals, and are utilized to generate the chemical sulfamic acid Ling, Jundami, Proptraline, Miecaomeng, Sulfolaling, Fluorex, and so on.

1-Propanol Purification Method

A preparation method of chromatographically pure 1-Propanol, the specific preparation steps are as follows:
(1) Take 50g of shell-type activated carbon, dry it at 150°C for 8 hours, and put it in a desiccator to cool down for later use;
(2) Take 1000ml of analytically pure 1-Propanol into an extraction bottle, add 50g of pre-treated activated carbon in step (1) and shake for 30 minutes, then place it for 10 hours, filter and separate the activated carbon, put 1-Propanol into 1000ml of three-port distillation in the bottle;
(3) After installing the rectification equipment as required, further rectify the 1-Propanol in step (2), adjust the reflux ratio to 2:30, collect 96.5-97.5 fractions, and obtain chromatographically pure propanol, take samples for analysis and inspection According to the Q/12HB3730-2010 standard inspection, the finished product yield is about 88%.

1-Propanol Production Process

Main production method: liquid catalyst hydroformylation + hydrogenation

The hydroformylation reaction is the reaction of olefins and synthesis gas (CO+H2) to produce aldehydes with one carbon higher than the raw material olefins, and the obtained aldehydes are hydrogenated and converted into alcohols. At present, Rh-based homogeneous catalysis process and cobalt-based homogeneous catalysis process are mainly used for the preparation of aldehydes in olefin hydroformylation reaction.

There are two main production processes for 1-Propanol in China, the first is ethylene hydroformylation to synthesize propionaldehyde, propionaldehyde is catalytically hydrogenated to produce 1-Propanol, and the second is the hydrogenation of allyl alcohol to produce 1,4-butanedi Alcohol by-product n-propanol method, there are only two domestic enterprises using this method, but the output is small, most domestic enterprises adopt the first method, the technology is relatively mature, water-soluble catalyst and oil-water two-phase reaction system, catalyst It exists in the water phase, and the product aldehyde is located in the oil phase. After the reaction, the catalyst and the product can be effectively separated by standing still. However, due to the low mass transfer efficiency of the two-phase reaction, which affects the catalytic effect, a phase transfer agent needs to be added, but the addition of the phase transfer agent It will lead to emulsification and increase the difficulty of phase separation. During the production process, as the activity of the catalyst decays, part of the catalyst must be discharged, and at the same time, an equal amount of catalyst must be replenished, which complicates the treatment process.

Ecological Information on 1-Propanol

The manufacturing and also use of 1-Propanol as a solvent, chemical intermediate, ruminant feed supplement, as well as also preference as well as likewise scent in food may cause its launch to the ambience using numerous waste streams. N-propanol takes place in nature as a result of animal excrement, microbes (by means of metabolic processes), plants (through fermentation in addition to degeneration), volcanoes, insect venom, as well as fusel oil exhausts. If released to air, the vapor stress and anxiety at 25 ° C is 21 mm Hg, showing that n-propanol will exist just as a vapor in the ambient setting. Vapor-phase 1-Propanol will certainly degrade cost-free radicals in the ambience by reacting with photochemically produced hydroxyl groups; this reaction has a half-life in air of 2.9 days. If released into dirt, n-propanol is prepared for to be exceptionally mobile based upon a Koc of 33. Volatilization from wet dust surface areas is prepared for to be a crucial fate process/mole based upon Henry’s law constant of 7.41X10-6 atm-cu m. 1-Propanol might evaporate from entirely dry soil area depending upon its vapor anxiety. If released right into water, n-propanol is not expected to adsorb to suspended solids as well as likewise debris based on the estimated Koc. n-Propanol is conveniently broken down in cardiovascular systems; half-lives for cardiovascular damage making use of sewage sludge inoculum varied from <1 day to 11 days. n-propanol has actually likewise been shown to break down easily under anaerobic troubles. Volatilization from the water surface area is expected to be an essential destiny procedure based upon the Henry’s guideline constant for this substance. The estimated volatilization half-lives were 62 hours and likewise 31 days for the variation river and also version lake, especially. An approximated BCF of 3 shows a lowered bioconcentration opportunity in aquatic microorganisms. Hydrolysis is not prepared for to occur because of the absence of hydrolyzable practical teams. Work 1-Propanol exposure might happen with inhalation and also facial direct exposure to this compound in workplace where 1-Propanol is produced or utilized. Surveillance information recommend that the fundamental populace might go through n-propanol through inhalation of ambient air, intake of artificial additive and also all-natural products, as well as facial contact with customer products containing n-propanol.
