Description of Rhenium standard solution

• Ammonium perrhenate (APR) is the ammonium salt of perrhenic acid, NH4ReO4. It is the most common form in which rhenium is traded. It is a white, water-soluble salt. It was first described soon after the discovery of rhenium.

What is Ammonium perrhenate?

With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is Mannitol  which has developed particularly rapidly in recent years. Do you know about Mannitol ?

The official answer：Mannitol, with the chemical formula C6H14O6, is a sugar alcohol and is a tautomer of sorbitol. Easily soluble in water, it is a white crystalline powder with a sweet taste similar to that of sucrose. Mannitol, also known as mannitol, is a six-carbon polyol extracted from brown algae cells and has two configurations: D and L. The L configuration is synthetic and does not exist in nature, while the D configuration is widely distributed in the plant world. Mannitol is a kind of storage material in the cells of brown algae, and kelp and other large brown algae are the main raw materials for mannitol extraction. The mannitol extracted from kelp, synthesized with niacin, has an obvious effect of relieving angina pectoris and has a good effect on hyperlipidemia. It can treat conditions such as high cholesterol, hypertension, and atherosclerosis. Mannitol is also a dehydrating agent and can be used medically. When injected into a vein with its 20% solution, it causes a momentary increase in blood osmolarity as it is rarely broken down in the body in order to allow water from the tissues to enter the bloodstream, thus reducing edema in the tissues. When mannitol is filtered from the glomerulus, it is not easily reabsorbed in the renal tubules, causing the osmotic pressure of the original urine in the renal tubules to increase, bringing out a large amount of water and acting as a diuretic. The above information is edited and compiled by Tong Tong.

What’s the application of Ammonium perrhenate?

Mannitol is a good diuretic, intracranial pressure, intraocular pressure, kidney medicine, dehydration medicine, sugar substitute, and also used as an excipient for tablets and diluent for solids and liquids.
As a hypertonic antihypertensive drug, Injection Manitou is a commonly used drug for clinical resuscitation, especially for brain disorders, and has the characteristics of fast and accurate antihypertensive effects required by drugs for lowering intracranial pressure. After entering the body, mannitol can increase the plasma osmolarity and dehydrate the tissues, which can lower the intracranial pressure and intraocular pressure. After filtration from the glomerulus, it is not easily reabsorbed by the renal tubules, which increases the urinary osmolarity and brings out a large amount of water and dehydration, and is used for edema caused by cranial trauma, brain tumor, brain tissue hypoxia, edema caused by large burns, and ascites glaucoma caused by renal failure. It can also be used to prevent and control early acute renal insufficiency.
As an excipient for tablets, mannitol is non-hygroscopic, fast-drying has good chemical stability, and has the characteristics of crispness, good granulation, etc. It is used in most tablets of anti-cancer drugs, antibacterial drugs, antihistamines, and vitamins. In addition, it is also used in chewable tablets such as sobriety drugs and mouth coolers.
Although mannitol can be absorbed by the human stomach and intestines, it does not accumulate in the body. After being absorbed, part of it is metabolized in the body and the other part is excreted in the urine.
Mannitol is more widely used in the manufacture of chewable tablets such as sobriety drugs and mouth coolers because it absorbs heat when dissolved, has a sweet taste, and is comfortable for the mouth, and its granular form is used exclusively as an excipient for direct compression of tablets. In foodstuffs, it has the least water absorption among sugar and sugar alcohols, and has a refreshing sweetness, and is used for anti-adhesive of maltose, chewing gum, rice cake, and other foodstuffs, as well as for anti-adhesive powder of general cakes. Dibromomannitol can be produced by the reaction of hydrobromic acid.
It can also be used as a sweetener with low caloric value and low sugar in foods for diabetics and bodybuilding foods.
