Formic Acid
> >
Formic acid is one of the basic raw materials of organic chemical, often used for chemicals, rubber coagulator and textile, printing and dyeing, electroplating, leather, pharmaceutical and other industries.
1. Agriculture
1)The preservation of silage and grain, can be used for storage, storage agent, antiseptic agent
Formic acid is one of the most powerful pH in organic acids. In addition to inhibit the growth of mold and spoilage bacteria, can improve the content of soluble carbohydrates in the feed, to prevent protein hydrolysis. In the course of silage or rumen digestion, formic acid can be decomposed into carbon dioxide and methane, which can be used to feed the livestock without poison. The addition of formic acid 2.85kg (United Kingdom) or concentration of 85% 4.53kg (United States) to 90% per ton of raw materials. Acidified silage advantages: bright green color, flavor, high quality (protein loss of only 0.3 ~ 0.5%, general silage loss of 1-2%; crude fiber decrease; carotene, vitamin C, calcium, phosphorus loss).

2)Animal feed additives
A.To reduce the pH value of the diet, so that the stomach pH value is decreased, improve the activity of the enzyme. Animal feed in formic acid can lead to a decrease of intragastric pH value, so as to activate pepsin, promote the decomposition of protein, and this decomposition can stimulate duodenal secretion more trypsin and enable complete protein decomposition and absorption. At the same time, the pH of the stomach can enhance the activity of other kinds of digestive enzymes.

B. Improving the microbial flora of the gastrointestinal tract. Acidifier by decreasing intestinal pH can inhibit the propagation of harmful microorganisms, reduce the consumption of nutrients and anti growth and toxin production, while promoting probiotics value-added

C. Other functions. Gastric emptying rate of stimulation factors for gastric content volume and pH value, the acidic chyme into the small intestine can be on the wall of the small intestine for chemical and mechanical stimuli and the secretion of enterogastrone, reflex inhibition of gastric motility, slow down the rate of gastric emptying is proteins have more time to digest in the stomach, reduce the burden on the small intestine.

2.Pharmaceutical industry
In Pharmaceutical and pesticide industry acid used as local stimulation drugs, foaming paste and astringent and so on, camphor, vitamin B1, cocoa alkali borneol, caffeine, analgin, metronidazole, carbamazepine, aminopyrin, aminophylline, toluene imidazole drugs such as an important raw material, in a new process of synthesis of insulin.

3.Leather industry
Formic acid used as leather depilation, ash removal, expansion and soft agent. Formic acid instead of sulfuric acid used for dyeing and disinfection, to prevent damp leather mildew

4.Textile Industry
In textile and dyeing industry, formic acid used to eliminate printing Tyco submicron sodium nitrate method of nitrite gas agent, weak acid dyes, neutral dyes dyeing auxiliaries and reactive dyes dyed nylon dye. Formic acid is not in the process of printing and dyeing residues in the fabric, acid stronger than acetic acid, can make six mediated reduction of chromium, so it can improve the utilization rate of the dye in the chrome mordant process. Using formic acid instead of sulfuric acid can avoid the degradation of cellulose, and the acidity is moderate, and the dyeing is used, so it is a kind of good auxiliary agent.

5.Chemical Industry
Calcium formate, sodium formate, ammonium formate, potassium formate, formic acid ethyl ester, acid barium, dimethyl formamide, formamide, rubber antioxidant, pentaerythritol, neopentyl glycol, ethylene soybean oil, soybean oil acid, octyl ester epoxy, pivaloyl chloride, paint stripping agent and phenolic resin, pickling plate.

6.Rubber Industry
Formic acid as coagulant can make high quality natural rubber, reduce the production cost, but also can be used for the regeneration of waste rubber.

7.Paper Industry
Formic acid soluble lignin, and the fiber of the polymerization degree reduce damage, so the formic acid instead of caustic soda and sodium sulfite pulp production, pulp production time is shortened and the yield is up to 72.2%.

8. Food Industry
In the food industry, formic acid is used as a disinfectant, antiseptic, and wine making industry to help the fermentation, and the juice and food preservative.
