What is N-Propanol?

Propanol is a substance in which one of the hydrogen atoms in the lp particle is changed by a hydroxyl team. Due to the fact that the hydroxyl team can replace the hydrogen on both ends of the carbon chain or on the center carbon atom, two isomers, n-propanol and isopropanol, can be produced.
The chemical residential or commercial properties of n-propanol are similar to ethanol. It is a by-product of the synthesis of methanol from carbon monoxide and hydrogen. It is a colorless, transparent liquid with a fragrance at space temperature level and also typical stress. Industrially, it is prepared from ethylene, carbon monoxide and also hydrogen under high pressure and also cobalt catalysis. It is prepared from the hydration of propylene under the activity of sulfuric acid or from acetone with catalytic hydrogenation. It is usually utilized as a solvent. It is annoying to the eyes and also mucous membranes. Inhaling propanol vapor can trigger lightheadedness, frustration, throwing up, etc.

N-Propanol Uses

  1. n-Propanol is usually used as a solvent and is likewise a resources for preparing n-propylamine, and so on .
  2. n-Propanol is utilized as chromatographic analysis reagent, solvent and also cleaner.
  3. n-Propanol is directly made use of as a solvent or to synthesize propyl acetate. It is used in layer solvents, publishing inks, cosmetics, and so on. It is utilized in the manufacturing of medicines and also pesticides as intermediate n-propylamine, as well as in the production of feed ingredients, artificial tastes, etc. Propanol is utilized in the pharmaceutical industry to produce probenecid, sodium valproate, erythromycin, epileptic acid, sticky hemostatic agent BCA, propylthiamine, dipropyl 2,5-pyridinedicarboxylate, and so on; Different esters manufactured from propanol are used in several elements such as artificial additive, plasticizers, seasonings, etc. By-products of n-propanol, specifically di-n-propylamine, have several applications in medicine and also pesticide manufacturing, and also are made use of to generate chemical aminesulfonate. Lingmao, Diprofen, Propyrrolidone, Trimethonol, Sulfonalin, Trifluralin, etc.
  4. n-Propanol is used as a solvent as well as cleaning agent for vegetable oils, natural rubber, materials and also cellulose esters. Organic Synthesis. Gas chromatography criteria.

N-Propanol Purification Method

An approach for preparing chromatographically pure propanol. The details preparation actions are as follows:
( 1) Take 50g of nutshell triggered carbon, dry it at 150 ° C for 8 hours, after that put it in a desiccator to cool for later use;
( 2) Take 1000ml of analytically pure propanol and also placed it into the removal bottle, add 50g of the activated carbon pre-treated symphonious (1 ), tremble for half an hour, leave it for 10 hours, filter to divide the activated carbon, as well as put N-Propanol right into a 1000ml three-neck distillation bottle. center;
( 3) After installing the purification tools as called for, further distill N-Propanol in step (2 ), adjust the reflux ratio to 2:30, collect 96.5-97.5 portions, and also obtain chromatographically pure propanol. Take samples for analysis as well as inspection. According to Q/12HB3730 -2010 typical assessment, the completed item return is approximately 88%.

N-Propanol Preparation

The tidy manufacturing process of hydrogenating propionaldehyde to n-propanol consists of the complying with actions:
a. When propionaldehyde is hydrogenated to produce crude propanol and also gets in the distillation system, the light elimination tower condenses and also warmth exchanges the three-phase azeotrope deposit formed by the reaction spin-off propyl propionate, water and also n-propanol., into the pervaporation membrane layer dehydration tool;
b. The gas phase product divided by the pervaporation membrane layer dehydration gadget is compressed to acquire wastewater A. The wastewater A is blended with the raw material propionaldehyde and gets in the system once more. The condensed residual gas is evacuated by the vacuum pump; the fluid stage material divided by the pervaporation membrane dehydration device is Send it to distillation to different n-propanol and propyl propionate in the liquid phase product.
