甲酸能否作为金属清洗剂?

来源:http://www.jnjdbc.cn/ 日期:2021-04-22 发布人:guanli
甲酸有个有趣的名字叫做蚁酸,提到蚁酸大家可能想到乙酸,但这二者可并非同一种。蚁酸的酸性较强,而且是有腐蚀性的,我们在使用此类物品的时候,要做好防护工作。近来,有不少人疑惑,蚁酸可以作为金属清洗剂来使用么?至于答案,我们一起去寻找一下吧。
Formic acid has an interesting name called formic acid. When it comes to formic acid, you may think of acetic acid, but the two are not the same. The acid of formic acid is strong and corrosive. When we use this kind of goods, we should do a good job in protection. Recently, many people have been wondering whether formic acid can be used as a metal cleaning agent. As for the answer, let's find out.
甲酸的结构特殊,它的一个氢原子和羧基直接相连。因此同时具有酸和醛和性质。 它具有和醛类似的还原性。它能起银镜反应,把银氨络离子中的银离子还原成金属银,而自己被氧化成二氧化碳和水。它是单一能和烯烃进行加成反应的羧酸。它在酸的作用下(如硫酸,氢氟酸),和烯烃迅速反应生成甲酸酯。
Formic acid has a special structure. One of its hydrogen atoms is directly connected with the carboxyl group. Therefore, it has both acid and aldehyde properties. It has reducibility similar to aldehyde. It can act as a silver mirror reaction, reducing silver ions in silver ammonia complex ions to metallic silver, and being oxidized to carbon dioxide and water. It is a single carboxylic acid that can react with olefins. In the presence of acids (such as sulfuric acid, hydrofluoric acid), it reacts rapidly with olefins to form formates.

它作为有机酸的其中之一,酸性比盐酸小,而比碳酸的酸性强,它是简单羧酸类化学品,因为自身拥有一定的水溶液,所生成的甲酸盐都能溶解于水,因而可作为化学清洗剂。所以能溶解许多金属:銅、金、铟、铁、铝、锰、汞、钼、银、锌、铈、铼、钨等金属氧化物、氢氧化物及盐等。它不含氯离子的化学性能,还是其用于含不锈钢材料的设备的清洗的重要因素。它有其独特的化学性质,有的时候它的酸性可以用醋酸,以甲醛代替,还原性。但是它还有一定氧化性,是无可替代的,因此它可以作为金属的清洗剂来使用。
As one of the organic acids, it is less acidic than hydrochloric acid, but stronger than carbonic acid. It is a simple carboxylic acid chemical. Because it has a certain water solution, the formate can be dissolved in water, so it can be used as a chemical cleaning agent. So it can dissolve many metals: copper, gold, indium, iron, aluminum, manganese, mercury, molybdenum, silver, zinc, cerium, rhenium, tungsten and other metal oxides, hydroxides and salts. Its chlorine free chemical performance is also an important factor in the cleaning of equipment containing stainless steel materials. It has its unique chemical properties, sometimes its acidity can be replaced by acetic acid, formaldehyde, reducibility. But it also has a certain oxidation, is irreplaceable, so it can be used as a metal cleaning agent.
可见,蚁酸是可以作为金属清洗剂来使用的,看完本篇内容,大家是不是又了解到一个小常识呢,温馨提示大家在使用的时候要注意保护好自己哦。如果大家对于甲酸有需求,可以拨打我们的热线电话联系我们,我们定会为大家提供合适的产品。
It can be seen that formic acid can be used as a metal cleaning agent. After reading this article, do you know a little common sense? It's a warm reminder that you should protect yourself when you use it. If you need formic acid, you can call our hotline to contact us, we will provide you with suitable products.
