Product Description

Best hot selling Oxalic acid cas 144-62-7

Oxalic acid, also known as Oxalic acid, is a strong organic acid. The chemical formula is H2C2O4. The common oxalic acid usually contains two molecules of crystallinity water (H2C2O4·2H2O). Oxalic acid is widely found in spinach and plant rhubarb.

production method
1. Oxalic acid is found throughout nature, and is often present in the form of oxalates on the cell membranes of plants such as barberry, marigold, oxalis, and sorrel. Almost all plants contain calcium oxalate. The industrial production methods of oxalic acid mainly include sodium formate method, oxidation method, oxo synthesis method, ethylene glycol oxidation method, propylene oxidation method, and carbon monoxide coupling method.
(1). Sodium formate method Carbon monoxide is purified and reacted with sodium hydroxide under pressure to produce sodium formate. Then it is dehydrogenated at high temperature to form sodium oxalate. Lead oxalate is then leaded (or calcified), acidified, crystallized and dehydrated and dried. Process to obtain finished oxalic acid. The synthesis pressure of carbon monoxide and sodium hydroxide is generally 1.8-2.0 MPa. The dehydrogenation temperature is 400°C.
(2). Oxidation method Using starch or glucose mother liquor as raw materials, in the presence of ruthenium catalyst, oxidation reaction with nitric acid-sulfuric acid gives oxalic acid. The nitrogen oxides in the exhaust gas are sent to the absorption tower to produce dilute nitric acid. 

Oxalic acid is mainly used for the production of antibiotics and borneol and other drugs, and the extraction of rare metal solvents, dye reducing agents, tanning agents. In addition, oxalic acid can also be used to synthesize various oxalic acid esters, oxalates and oxamides, and the production of diethyl oxalate, sodium oxalate, and calcium oxalate is the largest. Oxalic acid can also be used for the production of cobalt-molybdenum-aluminum catalysts, metal and marble cleaning and textile bleaching. It is used to synthesize acidity modifiers such as urea formaldehyde resin and melamine formaldehyde resin. The pharmaceutical industry is used to produce oxytetracycline, chlortetracycline and other drugs. Mainly used as reducing agent and bleaching agent, mordant in printing and dyeing industry, also used to extract rare metals, synthesize various oxalic acid esters, oxalates and oxamides. It is used as an acidity regulator to synthesize adhesives such as urea formaldehyde resin and melamine formaldehyde resin. It can also add polyvinyl formal water-soluble adhesives to improve the drying speed and adhesive strength. It is an important organic synthetic raw material for the production of various oxalates, oxalates, oxamides, hydroquinone, pentaerythritol, gallic acid and other products. Pharmaceutical industry for the manufacture of chlortetracycline, terramycin, tetracycline, streptomycin, borneol, vitamin B1
2, phenobarbital and other drugs. The printing and dyeing industry is used as a color development aid and bleaching agent. The plastics industry is used to produce PVC, aminoplasts, and urea-formaldehyde plastics. The metallurgical industry is used to produce high-purity nickel, carbon rods, and precipitated rare earth metals. It is also used as a metal washing agent, tanning agent, chelating agent, catalyst, anaerobic adhesive and acrylate fast-setting inhibitor, machined rust remover, electroplating complexing agent, wood bleaching, marble cleaning and Oil refining and so on. It can be used as a shampoo additive in cosmetics; it is mainly used in the manufacture of chemical industry products; the pharmaceutical industry is used to manufacture antibiotics and other drugs; the printing and dyeing industry and the leather industry are widely used; as terpineol, glycerin and stearic acid in oil chemistry Ester preparations, etc.; in addition to aluminum products processing, carbide production has applications.

Product expansion

1> Cosmetic Raw Materials: Cosmetics is a variety of raw materials through a reasonable deployment of processing from the compound mixture. Cosmetics with a wide range of raw materials, different performance. According to the raw material properties and uses of cosmetics, can be divided into matrix materials and auxiliary raw materials in two categories. The former is a class of cosmetics in the main raw materials, cosmetics in the possession of a large proportion of the cosmetics play a major role in the role of the material. The latter is the formation of cosmetics, stability or to give color, smell and other characteristics of the role of these substances in the cosmetic formula is not used, but it is extremely important. Cosmetics are natural, synthetic or extracted from the role of different substances as raw materials, by heating, mixing and emulsification and other production processes processed from the chemical mixture.

2> Active Pharmaceutical Ingredients(API): API refers to the raw materials in the production of various types of preparations, which is the active ingredient in powder,crystal and paste for medicine use through chemical synthesis,plant extract, and preparations of biotechnology institute.It is one substance or mixture during the medicine making period, it can not be taken directly by patients.

3> Fragrance And Spices: Spice is a substance that can be scented by smelling or scented by taste, and is the raw material for the preparation of the fragrance. Spices are an important part of fine chemicals, it is composed of natural spices, synthetic spices and single fragrance.

4> Organic Raw Material: Intermediates are also known as organic intermediates. The use of coal tar or petroleum products as raw materials to produce dyes, pesticides, pharmaceuticals, resins, additives, and other intermediates.

5> Chemicals Used In Paints: Paint, the traditional Chinese name is paint. So-called coating is coated on the surface of the object that be protected or be adornment, and with the continuous film coating to form strong adhesion, usually in resin, or oil, or emulsion is given priority to, add or not add pigment, filler, add the corresponding additives, organic solvents or water preparation of viscous liquid.
