Calcium formate is an organic substance with molecular formula CtwoHtwoOfourCa，It can be used as feed additive for all kinds of animals, with acidification, mildew prevention, antibacterial and other effects. It is also used in the industry for concrete, mortar additives, leather tanning or as a preservative.
[Physical and chemical properties] Slightly hygroscopic, slightly bitter.Neutral, non-toxic, soluble in water.The aqueous solution is neutral.The solubility of calcium formate has little change with the temperature rise, 16g/100g water at 0 ℃, 18.4g/100g water at 100 ℃.Specific gravity: 2.023 (20 ℃), bulk density: 900-1000g/L.Heating decomposition temperature>400 ℃.

1. As a new typefeed additive 。Feeding calcium formate for weight gain and using calcium formate as feed additive for piglets can promote appetite and reduce diarrhea rate of piglets.Adding 1%~1.5% calcium formate to the diet of piglets can significantly improve the performance of weaned piglets.The German study found that adding 1.3% calcium formate to the diet of weaned piglets can improve the feed conversion rate by 7%~8%, and adding 0.9% can reduce the incidence of diarrhea in piglets.Zheng Jianhua (1994) added 1.5% calcium formate to the diet of 28 day old weaned piglets and fed them for 25 days. The daily weight gain of piglets increased by 7.3%, feed conversion rate increased by 2.53%, protein and energy utilization rate increased by 10.3% and 9.8% respectively, and diarrhea of piglets was significantly reduced.Wu Tianxing (2002) added 1% calcium formate to the diet of three-way hybrid weaned piglets, which increased daily weight gain by 3%, increased feed conversion rate by 9%, and reduced diarrhea rate of piglets by 45.7%.Other things to note are that the use of calcium formate is effective before and after weaning, because the hydrochloric acid secreted by piglets increases with age;Calcium formate contains 30% calcium which is easy to be absorbed. Pay attention to adjusting the proportion of calcium and phosphorus when preparing feed.
2. It is used for building.Fast setting agent, lubricantEarly strength agent。be used forBuilding mortarIn all kinds of concrete, accelerate the hardening speed of cement and shorten the setting time, especially in winter construction, to avoid too slow setting speed under low temperature.Quick demoulding enables the cement to be put into use with higher strength as soon as possible.Use of calcium formate: various dry mixed mortar, various concrete,Wear-resistant material, floor industry, feed industry, tanning industry.Amount of calcium formate and precautions per tonDry mortarThe dosage of concrete is about 0.5~1.0%, and the maximum dosage is 2.5%.The amount of calcium formate gradually increases with the decrease of temperature. Even if the amount of 0.3-0.5% is used in summer, it will also have a significant early strength effect.
Production method

1. Neutralization method
Formic acid is neutralized with hydrated lime to produce calcium formate, which is refined to produce commercial calcium formate
2. Complex decomposition method
Sodium formate and calcium nitrate occur in the presence of catalystMetathesis reactionCalcium formate is obtained and sodium nitrate is co produced.After refining, commercial calcium formate is obtained.
The production of epoxy fatty acid methyl ester has developed rapidly, and a large amount of by-product formic acid will be produced in the production process of this product. One utilization scheme of this by-product formic acid is to produce calcium formate.
4. Pentaerythritol by-product method
PentaerythritolUse during productioncalcium hydroxideThe alkaline reaction conditions are provided, and the neutralization process of formic acid and calcium hydroxide is added in the follow-up of the reaction, while calcium formate is by-product.
