What Are The Uses Of Sodium Formate
Nov 16, 2021
(1) Used to produce formic acid
Formic acid can be obtained by reacting sodium formate with sulfuric acid. At the same time, sodium sulfate is a by-product, and the production process is simple.
The development and utilization of formic acid abroad is good, the application scope is expanding year by year, and the amount of formic acid is also increasing. The largest consumption of formic acid abroad is leather, which is used for tanning and leather treatment to prevent mildew. The second major use is agriculture, which is used to preserve green feed and grain.
(2) Used to produce oxalic acid
Sodium formate is dehydrogenated to sodium oxalate, which is leaded by lead sulfate and acidified by sulfuric acid to obtain oxalic acid.
Oxalic acid, scientific name: oxalic acid; molecular formula: c2h2o4, mainly used as reducing agent and bleaching agent, mordant in printing and dyeing industry, etc.; it is also widely used in rare earth refining. It is used in the pharmaceutical industry to produce antibiotics, borneol and other drugs. It is used to synthesize all kinds of oxalate, oxalate and oxalamide.
(3) Used to produce sodium bisulfite (sodium bisulfite)
Sodium formate, sodium pyrosulfite and liquid SO2 are synthesized in methanol medium to generate insurance powder suspension, which is then transferred to a four in one dryer for filtration, washing and vacuum drying. Soda ash is added into the package.
(4) It can be used as oil drilling fluid
Sodium formate has become a series of products for drilling fluid. Sodium formate drilling fluid system is a drilling fluid completion fluid system with semi permeable membrane effect. It forms a solid-free drilling mud system together with other chemical additives in oil drilling. It can achieve high density and low viscosity of mud, improve drilling speed and protect oil (gas) It is an advanced and environment-friendly material in the field of oil (gas) production technology. The use of sodium formate mud is conducive to stabilizing shale, reducing damage to rock stratum and ensuring the best working state of drilling and completion.
(5) Other uses of sodium formate
1. Environment friendly snow melting agent.
2. Gold extraction.
3. Export.
The exported sodium formate is generally used for concrete composite multifunctional water reducer and environmental protection snow melting agent.
