The application of sodium formate - Anhui Exuberant Additive Co., Ltd.

Sodium formate, HCOONa, is the sodium salt of formic acid, HCOOH. It usually appears as a white deliquescent powder. Sodium formate is a white crystalline powder with water absorbing performance and slight formic acid odor, soluble in water glycerol, sightly soluble in ethano, not soluble in ether. Sodium formate's melting point is 253°C.

The application of sodium formate is as following:

1. Produce the formic acid with sodium formate. Formic acid can be obtained after sodium formate reaction with sulfuric acid, sodium sulfate produced at the same time, the production process is simple. Foreign exploitation of formic acid is better, the application range has expanded each year, formic acid is also increasing. Formic acid consumption abroad is the largest leather tanning and leather for treatment, to prevent mildew. The second largest use is agriculture, for saving green fodder and cereals.

2. Produce the oxalic acid with sodium formate. For sodium formate dehydrogenation sodium oxalate and sodium oxalate through lead lead sulfate, sulfuric acid acidification, oxalic acid. Scientific name oxalic acid, oxalic acid; Molecular formula: C2H2O4, mainly used as a reducing agent and bleaching agent, mordant dyeing and printing industry etc. Also used in large amounts of rare earth extraction. In the pharmaceutical industry for the production of drugs such as antibiotics and synthetic borneol. Used in the synthesis of a variety of oxalate ester amide, oxalate and grass, etc.

3. Use the sodium formate as oil drilling fluid. Sodium drilling fluid system is a kind of semi-permeable membrane effect drilling fluid system in the oil drilling and other chemical additives to form a drilling mud solids-free system, which can achieve a high slurry density, low viscosity, improve drilling speed, protect the oil ( gas ) layer, sloughing, extending the life of the drill bit and wells. Oil ( gas ) in the field of mining technology an advanced and environmentally friendly materials. Using sodium formate mud, help stabilize shale formations to reduce the damage and ensure drilling and completion in the best working condition.

4. Sodium formate can also be used as environmentally friendly deicing salt and gold refining. The export of sodium formate is commonly used in concrete composite multi functional environment friendly snowmelt agent and water reducing agent.
