544-17-2 Usage

Description

Calcium formate is a white to almost white fine crystalline powder. It can be used an accelerator for the pozzolanic cement pastes. On the one hand, it shortens the initial and final setting times and increases the compressive strength and combined water content as well as gel/space ratio at all ages of hydration. On the other hand, it decreases the total porosity. It has been shown that it has a growth-promoting effect in weanling pigs challenged with E. coli, independently of their susceptibility to the intestinal adhesion of this strain. More importantly, calcium formate can be used as a nutrient supplement to the feed of young growing pigs or fattening poultry, further boosting the growth of animals and the feed utilization. At the same time, it causes a reduction of the occurrence of piglet diarrhea.

Chemical Properties

Different sources of media describe the Chemical Properties of 544-17-2 differently. You can refer to the following data:
1. Calcium formate, Ca(HCOO)2, is the calcium salt of formic acid, HCOOH. It is also known as food additive E238 in food industry. The mineral form is very rare and called formicaite. It is known from a few boron deposits. It may be produced synthetically by reacting calcium oxide or calcium hydroxide with formic acid.
2. Calcium formate is white solid, solubility at 0 °C 13.90 g, at 40 °C 14.56 g, at 80 °C 15.22 g of anhydrous salt per 100 g saturated solution, formed by reaction of calcium carbonate or hydroxide and formic acid. Calcium formate, when heated with a calcium salt of a carboxylic acid higher in the series, yields an aldehyde.

Uses

Different sources of media describe the Uses of 544-17-2 differently. You can refer to the following data:
1. Calcium Formate is Hydrophobic additives for construction materials.Formic Acid is used as a potential energy source in the preparation of fuel cells. Also used in chemical synthesis of various anti-inflammatory and anti-microbial agents.
2. Preservative for food, silage; as binder for fine-ore briquets; in drilling fluids and lubricants. Calcium formate is an organic salt suitable for use in pig and poultry diets. It acts as a feedstock preservative and has an acidifying effect on the gastro-intestinal tract, which promotes good gut-health. The efficiency of pig and poultry feedstock digestion is dependent on the indigenous micro-organism concentration in the gastro-intestinal tract. With the approaching ban on the use of prophylactic antibiotics in animal feed as a means to control disease and promote growth, alternatives are needed to limit the proliferation of pathogenic bacteria in the gut which can impair feedstock digestion as well as cause enteric diseases such as E. Coli and Salmonella. Acidifiers such as calcium formate preserve the feedstock before consumption and lower the pH in the gastro-intestinal tract, creating unfavourable conditions for these bacteria to grow. Calcium formate is used extensively in the leather industry as a masking agent in the chrome-tanning process. The addition of calcium formate to the tannage formulation promotes faster, more efficient penetration of the chrome in the leather. Calcium formate can also be used as a replacement for formic acid in the pickling operation.

Reactions

Calcium formate can be used to prepare solutions of other water-soluble formate salts. For example, the addition of nickel (II) sulfate to a solution of calcium formate results in the precipitation of insoluble calcium sulfate, leaving nickel (II) formate in solution: Ca(OOCH)2 + NiSO1 → CaSO4 + Ni(OOCH)2 In a similar reaction, sulfuric acid reacts with calcium formate to provide low-cost solutions of formic acid: Ca(OOCH)2 + H2 SO4 → CaSO4 + 2HCOOH When heated, calcium formate decomposes to calcium carbonate and formaldehyde: Ca(OOCH)2 → CaCO3 + HCHO Calcium formate can be used as a low-cost reducing agent in the conversion of carboxylic acids to aldehydes. This process is an effective substitute for the troublesome Rosenmund reduction. (RCOO)2Ca + (HCOO)2CA → 2RCH + 2CaCO3

Hydrogenation of aqueous mixtures of calcium carbonate and carbon dioxide using a water-soluble rhodium(I)-tertiary phosphine complex catalyst

Jószai, István,Joó, Ferenc

, p. 87 - 91 (2004)

Aqueous suspensions of calcium carbonate were hydrogenated to yield calcium formate under a gas phase containing both H2 and CO2. A rhodium(I)-complex of monosulfonated triphenylphosphine (mtppms), [RhCl(mtppms)3] was used as catalyst. Reaction temperatures were in the range of 20-70°C, total pressure 10-100 bar with an optimum p(CO 2):p(H2) ratio of 1:4. Due to the mobile bicarbonate-formate equilibrium, the highest available formate concentration is decreased with increasing temperature but increased with increasing pressure. Interestingly, at 50°C and 100 bar total pressure the yield of formate was 143% (based on CaCO3) which implies the formation of free formic acid in the reaction of CO2 from the gas phase. The dependence of the hydrogenation rate on the catalyst and ligand concentrations, as well as that of the decomposition of formate as a function of temperature were also studied. A mild method has been developed for the hydrogenation of calcium carbonate to calcium formate in aqueous suspensions under CO2 + H2 pressure catalyzed by [RhCl(mtppms)3] (mtppms = monosulfonated triphenylphosphine) at 20-70°C and 10-100 bar total pressure. In certain cases the yield of formate exceeded 100% (based on CaCO3) which implies the concomitant hydrogenation of carbon dioxide, too.

Eco-friendly upconversion of limestone into value-added calcium formate

Gunasekar, Gunniya Hariyanandam,Padmanaban, Sudakar,Park, Hongjin,Yoon, Sungho

, p. 4995 - 5001 (2020)

Although CaCO3 is a naturally available, inexpensive, abundant and extensively used chemical in various industries, to date, most of its conversions liberate CO2 into the atmosphere, which accounts for about 5-6% of global anthropogenic CO2 emission. Herein, the first synthesis of calcium formate (CF) by hydrogenation of an aqueous mixture of CaCO3 and CO2 using a heterogeneous catalyst in an unconventional CO2 reducing manner is reported. The phosphine-based heterogenized Ru catalyst efficiently converts CaCO3 into CF with good selectivity (>99%) and is readily separated from the reaction product, resulting in promising recycling ability. Thus, this work provides a promising strategy for the design of green and sustainable conversion of carbonate minerals in industry.

A a method of preparing calcium

-

Paragraph 0022-0023, (2017/07/07)

The invention discloses a preparation method of calcium formate and belongs to the technical field of chemical synthesis. The preparation method of the calcium formate comprises the following steps: carrying out dust removal on semi-water gas, desulphurizing, compressing, carbonizing and recompressing to 3-5MPa to obtain feed gas, reacting with a calcium hydroxide turbid liquid in the presence of ammonia or amine to generate a calcium formate aqueous solution containing ammonium formate or amine formate, adding right amount of lime milk and carrying out a replacement reaction in a calcium formate aqueous solution concentrating process, so that calcium formate precipitate is obtained. The preparation method of the calcium formate has the advantages that a reaction accelerator volatile alkali is used in a process that the feed gas reacts with the calcium hydroxide turbid liquid, generation of formate ions in reaction between carbon monoxide and hydroxyl ions is sped up, and concentration of a formate solution generated by the reaction between the carbon monoxide and hydroxyl ions is greatly increased, so that energy consumption in a concentration process is reduced, and coproduction of calcium formate and sodium formate can be realized on the basis of the original synthetic ammonia production system.
