Formic acid (HCOOH) is an organic acid, which is stronger than carbonic acid and weaker than hydrochloric acid, with pungent smell and strong corrosivity. Formic acid is secreted when ants and mosquitoes bite, so formic acid is also known as formic acid. The following are common formic acid problems, hoping to popularize relevant knowledge of formic acid for everyone:

　　1、人被蚊蟲叮咬后會(huì)癢痛，可以涂抹下列物質(zhì)中的肥皂水消除。

　　1. People will itch after being bitten by mosquitoes, which can be eliminated by smearing soapy water in the following substances.

　　2、白螞蟻除了會(huì)蛀蝕木頭以外，它分泌的蟻酸還會(huì)腐蝕很多建筑材料，如銅欄桿、鋼筋、大理石等。

　　2. In addition to eating wood, the ant acid secreted by white ants can also corrode many building materials, such as copper railings, steel bars, marble, etc.

　　3、使用濃硫酸作催化劑，在加熱的條件下，甲酸分解得到一種常見的有毒氣體和另一種氧化物

　　3. Using concentrated sulfuric acid as catalyst, formic acid decomposes into a common toxic gas and another oxide under heating conditions
       

　　傳統(tǒng)產(chǎn)方法主要有：甲酸鈉法、甲酰胺法、丁烷(或輕油)液相氧化法和甲酸甲酯水解法四種。

　　The traditional production methods include sodium formate method, formamide method, butane (or light oil) liquid phase oxidation method and methyl formate hydrolysis method.

　　Introduction of new process for preparation of formic acid

　　在新技術(shù)路線開發(fā)方面，其主要研發(fā)路線有：甲酸前體——甲酸甲酯制備技術(shù)、甲醛一步法直接氧化催化生成甲酸、CO2直接加氫制取甲酸、合成氣直接制甲酸。其中，甲醇羰基化制甲酸甲酯工藝和甲醇催化脫氫制甲酸甲酯工藝近年來國內(nèi)外研究較多，并有很多已經(jīng)工業(yè)化。

　　In terms of the development of new technology routes, the main research and development routes are as follows: preparation technology of formic acid precursor methyl formate, one-step direct oxidation and catalysis of formaldehyde to formic acid, direct hydrogenation of CO2 to formic acid, and direct synthesis of formic acid from syngas. Among them, carbonylation of methanol to methyl formate and catalytic dehydrogenation of methanol to methyl formate have been widely studied at home and abroad in recent years, and many of them have been industrialized.
