What is Glycerol?
Glycerin was first discovered by Scheel in 1779. In 1823, people understood that the oil part contained Chevreul, which means sweet in Greek, so it was called Glycerine. During the First World War, since it was the raw product for making gunpowder, the production increased greatly.
Appearance as well as Feature: Anemic thick fluid, odorless, with a cozy sweetness that can soak up dampness.
Solubility: Miscible in ethanol, miscible with water, insoluble in chloroform, ether, carbon disulfide, benzene, oils. Some inorganic substances can be liquified.
Gas chromatographic fixed liquid (the highest temperature is 75 ℃, the solvent is methanol), which can divide and also assess low-boiling oxygen-containing compounds, amine substances, nitrogen or oxygen heterocyclic substances, as well as can completely separate 3-methylpyridine (boiling point 144.14 ℃) as well as 4 -Picoline (boiling point 145.36 ° C), appropriate for evaluation of aqueous solutions, solvents, gas meters as well as shock absorbers for hydraulic presses, softeners, nutrients for antibiotic fermentation, desiccants, lubricating substances, pharmaceutical industry, cosmetic preparation, natural synthesis, Plasticizer. It can be liquified with water in any percentage, as well as the low-concentration glycerol solution can be made use of as lubricating oil to hydrate the skin (Kaisailu).
The chemical name of glycerin is glycerol, which has solid water absorption. Due to its appearance as a clear as well as viscous liquid, many people error it for an oil. In fact, glycerin is an alcohol, a material that is better to alcohol. Glycerin takes in rapidly, and it is a great hydrating product for skin that removes in seasons, skin with acne scars, and also delicate skin. In addition to being used to wipe hands and feet, glycerin is additionally very efficient in avoiding chapped lips.
Glycerol Uses
- Damping
Glycerin is used as the filler of the pressure gauge to suppress vibration. External vibration from compressors, engines, pumps, etc. will produce harmonic vibration in the Boden instrument, resulting in excessive movement of the pointer and inaccurate readings. Excessive swing of the needle will also damage the internal gear or other components, resulting in premature wear. - Film industry
The film industry uses glycerin when shooting scenes involving water to prevent the area from drying too quickly.
Use glycerin – mixed with water (about 1:99) – to create a smooth smoke environment. - Internal combustion engine fuel
Glycerin is also used to power diesel generators and FIA Formula e series electric racing cars. - Chemical intermediates
Glycerol is used to produce nitroglycerin, which is the basic component of various explosives (such as explosives, open flames) and propellants (such as cordierite). Relying on soap making to supply glycerol, a by-product, made it difficult to increase production to meet wartime needs. Therefore, the synthetic glycerol process was the focus of national defense before World War II. Nitroglycerin, also known as triglyceride (GTN), is usually used to alleviate angina pectoris and is taken in the form of sublingual tablets, patches or aerosol sprays. Trifunctional polyether polyols consist of glycerol and propylene oxide. Glycerol is oxidized to obtain medium oxalic acid. [36] dehydrate glycerol to obtain hydroxyacetone.

Application of Glycerol
Application 1
A preparation method of glycerophosphoric acid, using medical glycerol and food-grade phosphoric acid as raw materials, and the proportioning ratio (molar ratio) of the two is: glycerol:phosphoric acid≤1.0; The glycerol and phosphoric acid in the above proportions are reacted, and the reaction temperature is 120 ℃-150℃, the reaction pressure is vacuum, and the reaction time is 4-7 hours; the reaction solution is cooled down, hydrolyzed with deionized water, decolorized with sugar-grade activated carbon, filtered and packaged.
The process of the invention is simple and the conversion rate of raw materials is high.
Application 2
A method for synthesizing calcium glycerophosphate, which uses pharmaceutical glycerol and food-grade phosphoric acid as raw materials, carries out an esterification reaction in a reaction kettle, and after the reaction is completed, the reaction solution is cooled, then diluted with deionized water, and decolorized by activated carbon , then add a certain amount of calcium hydroxide, after ultrasonic stirring reaction, filter the reactant to obtain a clear filtrate, pass CO2 into the filtrate, keep the pH of the filtrate at 8-10, and filter again. Then alcohol is added to the filtrate, and after stirring, spray drying is performed to obtain a white powder, which is the product.
The process of the invention is simple and the cost is low; the quality of the synthesized calcium glycerophosphate is stable and conforms to the standard of the 63rd edition of the European Pharmacopoeia.
Application 3
CN201510880617.1 discloses selenium disulfide ultrafine powder and a preparation method thereof, and belongs to the field of washing products. The invention solves the quality problems that the selenium disulfide ultrafine powder prepared by medium ball milling has long production time as a lotion, and the selenium disulfide particles are large, unevenly dispersed and unstable.
The particle size of the selenium disulfide ultrafine powder in the present invention is (1-50) μm. The method of the invention is as follows: 1. Mix selenium disulfide dry powder, purified water, pharmaceutical grade titanium dioxide and pharmaceutical glycerin evenly, and then add citric acid to adjust the pH value between 3.5 and 4.5; The ultrafine powder of selenium disulfide is obtained by grinding and pulverizing in an ultrafine pulverizer.
The selenium disulfide ultrafine powder of the present invention can be applied to daily chemical products such as lotions, shampoos, conditioners and the like.
Preparation of Glycerol
A method for purifying medicinal glycerol, comprising the steps:
S1, the muscovite is ground, and the barium nitrate aqueous solution is added to mix and stir, and the pH value of the system is adjusted with hydrochloric acid to be 5.5 to 6.5, and hexadecyltrimethylammonium chloride is added to heat up and stir, filter, and wash to obtain pretreated muscovite;
