Physical property parameters of niacin

Niacin is also known as vitamin B3 or vitamin PP; its molecular formula is C6H5NO2. It is heat-resistant and can sublimate. Niacin, also known as nicotinic acid or antipellagra factor. In the human body, it also includes its derivative nicotinamide or niacinamide. It is one of the 13 vitamins essential for the human body; it is a water-soluble vitamin that belongs to the B complex. Niacin is converted into nicotinamide in the human body, and nicotinamide is a component of coenzyme I and coenzyme II; it plays a role in lipid metabolism, the oxidative processes involved in tissue respiration, and the anaerobic breakdown of carbohydrates. Niacin and nicotinamide are both soluble in water and alcohol ； Niacin and nicotinamide have relatively stable properties and are not easily destroyed under acidic, alkaline, oxygenous, light, or heating conditions ； It remains undamaged under high pressure at 120°C for 20 minutes. Generally, the losses during processing and cooking are minimal, but they can be lost along with water.

Nicotinic acid; Vitamin B5; 3-Pyridinecarboxylic acid; Nicotinic acid; 3-Pyridinecarboxylic acid; Niacin; Vitamin B5. Molecular formula: C6H5NO2; Molecular weight: 123.11; CAS number: 59-67-6. Properties: Colorless needle-shaped crystals. The melting point is 236°C. 1 gram of this substance dissolves in 60 ml of water; it is readily soluble in boiling water and boiling alcohol, but insoluble in propylene glycol, chloroform, and alkaline solutions, as well as in ethers and lipid solvents. It can sublimate, is odorless, with a slight sour taste. Preparation method: Obtained by the oxidation and acidification of 3-methylpyridine. Another method using 3-methylpyridine as a starting material is gas-phase ammonia oxidation. A fluidized-bed reactor is used to mix 3-methylpyridine, air, and ammonia in proportion, and the mixture is reacted at 290–360 degrees under the action of a vanadium catalyst. The obtained nicotinonitrile was hydrolyzed with sodium hydroxide at 160°C. If hydrolysis is carried out using ammonia, by controlling the solubility during hydrolysis, nicotinic acid or nicotinamide can be obtained respectively. Nicotinic acid can also be produced from nicotine (tobacco). A fluidized-bed reactor was used, with ammonium iron citrate as a catalyst, and gas-phase oxidation was carried out using air at 65–105°C. In industry, quinoline can also be used as a starting material to produce nicotinic acid, with common methods including ozone oxidation and decarboxylation, or nitric acid oxidation and decarboxylation. Use: This product is a vitamin drug; together with nicotinamide it is known as vitamin PP. It is used to treat pellagra, can also function as a blood dilator, and is widely used as an additive in food and feed. As a pharmaceutical intermediate, it is used in the production of isoniazid, nicotinamide, nicorandil, and inositol nicotinate.

Thank you; all of this can be found. What I need are the physical property parameters, in order to calculate the area required for the heat exchanger
