2.This product is toxic. For protection methods, see formic acid. Generally, intermediates are used for their own use.

Storage method

1. Store in a sealed and dry container. It can be packed in plastic bags lined with plastic bags or woven bags coated. Storage and transportation in accordance with general chemical regulations.

Synthesis method

1. Industrially, it is obtained by reacting carbon monoxide and sodium hydroxide at 150-170℃ and about 2MPa. In fact, the production process of sodium formate is part of the production of oxalic acid, and the concentration of sodium hydroxide solution used for the absorption reaction is 25%-30%. Sodium formate can also be prepared by reacting formic acid with sodium oxyoxide or sodium bicarbonate. Raw material consumption quota: carbon monoxide (>28%) 1630kg/t, caustic soda (>30%) 2160kg/t.

2. Pentaerythritol by-product.

3. It is formed by the reaction of carbon monoxide and sodium hydroxide at 160℃ and 2MPa.

4.Produced by the reaction of carbon monoxide and sodium hydroxide. Or it can be obtained by reacting formic acid with sodium hydroxide or sodium bicarbonate.

5. React with sodium bicarbonate solution and formic acid, remove impurities, concentrate and crystallize, and then wash with ethanol to obtain:



1. Mainly used to produce formic acid, oxalic acid and insurance powder.

2. Used as reagent, disinfectant and mordant for determination of phosphorus and arsenic.

3. Preservatives. Has diuretic effect. EEC countries are allowed to use it, but the UK is not allowed to use it.

4. It is an intermediate in the production of formic acid and oxalic acid, and is also used in the production of dimethylformamide, etc. Also used in medicine, printing and dyeing industries. It is also a precipitant for heavy metals.

5. Used in alkyd resin coatings, plasticizers, high explosives, acid-resistant materials, aviation lubricants, and adhesive additives.

6.Heavy metal precipitant can form trivalent metal complex ions in solution. Reagents for the determination of phosphorus and arsenic. Also used as a disinfectant, astringent, and mordant. It is also an intermediate in the production of formic acid and oxalic acid, and is used in the production of dimethylformamide, etc.

7.Used for nickel-cobalt alloy electrolyte plating.
