Description of Formic acid

Formic acid (also called methanoic acid) is the simplest carboxylic acid. The chemical formula is HCOOH or HCO2H. It is an important intermediate in chemical synthesis and occurs naturally, most notably in some ants. The word “formic” comes from the Latin word for ant, formica, referring to its early isolation by the distillation of ant bodies. Esters, salts, and the anions derived from formic acid are called formates.

What is Formic Acid?

With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is formic acid which has developed particularly rapidly in recent years. Do you know about Formic acid?

The official answer: Formic acid is an important chemical material, first discovered by Fisher in 1670 and first produced in its pure form by A.S. Margret in 1749. It was first discovered by distilling red ants, hence the name Chemicalbook. anthranilic acid is widely found in nature, in the secretions of red ants, bees, and caterpillars, in the leaves and roots of plants, and in fruits. The simplest of the carboxylic acids, it has a more specific structure and is more acidic than other fatty carboxylic acids.

What’s the application of Formic acid?

Part 2: In-depth development

Formic acid is one of the basic organic chemical raw materials and is widely used in the pesticide, leather, dye, pharmaceutical, and rubber industries. Formic acid can be used directly in fabric processing, tanning, textile printing and dyeing, and storage of green fodder, as well as metal surface treatment agents, rubber additives, and industrial solvents. In organic synthesis, it is used in the synthesis of various formic acid esters, acridine dyes, and formamide series of pharmaceutical intermediates. Specific classification is as follows.

Pharmaceutical industry: caffeine, anandamide, aminopyrine, aminophylline, cocaine ice, vitamin B1, metronidazole, mebendazole.

Pesticide industry: powder rusting, triadimefon, triazole, triazophos, poloxamer, allyl azole, insecticide ether, dicofol, etc.

Chemical industry: calcium formate, sodium formate, ammonium formate, potassium formate, ethyl formate, barium formate, dimethylformamide, formamide, rubber antioxidant, pentaerythritol, neopentyl glycol, epoxidized soybean oil, epoxidized soybean oil acid octyl ester, pivaloyl chloride, paint stripper, phenolic resin, pickled steel plates, etc.

Leather industry: tanning agents for leather, de-ashing agents, and neutralizers.

Rubber industry: natural rubber coagulant.

Other: also makes printing and dyeing mordants, dyeing agents for fibers and paper, treatment agents, plasticizers, food preservation, and animal feed additives, etc.

Preparation of CO. chemical formula.

Reducing agent. Determines arsenic, bismuth, aluminum, copper, gold, indium, iron, lead, manganese, mercury, molybdenum, silver, and zinc. Determination of cerium, rhenium and tungsten. Determination of aromatic primary and secondary amines. Determine relative molecular masses and solvents for crystallization. Determination of methoxy. Used as a fixative in microanalysis. Manufacture of formic acid salts.

Formic acid and its aqueous solutions can dissolve many metals, metal oxides, hydroxides, and salts, and the resulting formic acid salts are all soluble in water and can therefore be used as chemical cleaning agents. Formic acid does not contain chloride ions and can be used for the cleaning of equipment containing stainless steel materials.

Peter has been my partner for many years, we met at the Shanghai CPHI Fair in 2014, for the first time I didn't have much interest in Peter's products because our company had a stable supplier. Although we didn't work together, Peter would often send me important news and interesting trend information about the industry, so we became good friends, even though I didn't place any orders with him during this time, even if it was a sample order. In September 2016, our original supplier was unable to provide us with the quality and delivery guarantees we needed, so I first thought of Peter and his company. Until now, we have maintained a very good personal friendship in addition to a steady business relationship.

In all my years of sourcing from China, I first time to found that working with Sincere Chemical was so good, they helped me with all the production and delivery as well as a lot of technical expertise, which saved me a lot of time. When I first approached Peter for a quotation for Optical Brightener, he made me a detailed quotation with not only prices but also foreign trade details, company profile, company strengths, R&D capabilities, production capacity, packaging methods, raw material control, environmental protection, and much more. This information was a very important reference for me in making purchasing decisions. Sincere Chemical is a trustworthy supplier and I believe our business will grow from strength to strength!

Hi, I'm Kim, I'm Peter's partner and although I don't like him very much (because he never gives me more money for my prices, hahaha) I'm still willing to write him customer feedback. As an international buyer, I have to deal with a lot of things every day and my inbox is often full of development letters. It's a lot of junk and meaningless pleasantries, which I don't like that much, but Peter's emails always give me a better understanding of the product and the industry. I am also very pleased with his work ethic, and I am very happy with his work every time I work with him, not only in providing quotations but also in facilitating all the details of my work so that I can concentrate more on other things, so he is the best supplier for me. Although his prices are not the lowest among all suppliers, his products give me the greatest peace of mind.
