The most common regeneration process is the pyrohydrolysis process, applying the following formula: [25] 4 FeCl 2 + 4 H 2 O + O 2 → 8 HCl + 2 Fe 2 O 3. By recuperation of the spent acid, a closed acid loop is established. [7] The iron(III) oxide by-product of the regeneration process is valuable, used in a variety of secondary industries. [25]
Salicylic acid is an organic compound with the formula HOC 6 H 4 COOH. [3] A colorless (or, white), bitter-tasting solid, it is a precursor to and a metabolite of acetylsalicylic acid (aspirin). [3]
In chemistry, a superacid (according to the original definition) is an acid with an acidity greater than that of 100% pure sulfuric acid (H 2 SO 4), [1] which has a Hammett acidity function (H 0) of −12.
Ramon Cabanos Barba ONS (August 31, 1939 – October 10, 2021) was a Filipino inventor and horticulturist [1] [2] best known for inventing a way to induce more flowers in mango trees using ethrel and potassium nitrate. [3]
Citric acid is an organic compound with the skeletal formula H O C(CO 2 H)(CH 2 CO 2 H) 2. [10] It is a colorless weak organic acid. [10] It occurs naturally in citrus fruits.In biochemistry, it is an intermediate in the citric acid cycle, which occurs in the metabolism of all aerobic organisms.
Benzoic acid / b ɛ n ˈ z oʊ. ɪ k / is a white (or colorless) solid organic compound with the formula C 6 H 5 COOH, whose structure consists of a benzene ring (C 6 H 6) with a carboxyl (−C(=O)OH) substituent.
The log-normal distribution has also been associated with other names, such as McAlister, Gibrat and Cobb–Douglas. [4] A log-normal process is the statistical realization of the multiplicative product of many independent random variables, each of which is positive.
The Leuckart reaction is the chemical reaction that converts aldehydes or ketones to amines by reductive amination in the presence of heat. [1] [2] The reaction, named after Rudolf Leuckart, uses either ammonium formate or formamide as the nitrogen donor and reducing agent. [3]
