环己胺是一种有机化合物，属于脂肪族胺。纯的环己胺是无色液体，但胺类物质通常因混有杂质而带有颜色，环己胺也不例外。它带有鱼腥味，混溶于水，水溶液呈弱碱性，碱性比苯胺强。在有机合成中，环己胺是一种重要中间体。

Cyclohexylamine is an organic compound belonging to aliphatic amines. Pure cyclohexylamine is a colorless liquid, but amine substances usually have a color due to mixing with impurities, and cyclohexylamine is no exception. It has a fishy smell and is miscible in water. The aqueous solution is weakly alkaline, which is stronger than aniline. Cyclohexylamine is an important intermediate in organic synthesis.

环己胺是合成其他有机物的重要中间体。例如，它是除草剂环嗪酮、次磺酰胺类硫化促进剂的前体。次磺酰胺类促进剂是黏液促进剂、镇痛药、支气管扩张药等药物合成的重要组分。一些甜味剂通过环己胺合成得到，其中重要的是甜蜜素。另外，环己胺也是一种缓蚀剂。

Cyclohexylamine is an important intermediate in the synthesis of other organic compounds. For example, it is a precursor of herbicides such as cycloazinone and sulfosamide vulcanization promoters. Hyposulfonamides are important components in the synthesis of mucus enhancers, analgesics, bronchodilators, and other drugs. Some sweeteners are synthesized through cyclohexylamine, the most important of which is cyclamate. In addition, cyclohexylamine is also a corrosion inhibitor.

环己胺燃烧时分解，生成含有氮氧化物的有毒、腐蚀性烟雾。

When cyclohexylamine is burned, it decomposes to produce toxic and corrosive smoke containing nitrogen oxides.

氢氧化钾厂家提醒您，环己胺是一种强碱。与酸发生剧烈反应，并腐蚀。与强氧化剂急剧地发生反应，产生着火的危险。其可浸蚀铝、铜和锌。

The potassium hydroxide manufacturer reminds you that cyclohexylamine is a strong base. Reacts violently with acids and corrodes. Reacts rapidly with strong oxidizing agents, creating a risk of ignition. It can etch aluminum, copper, and zinc.

环己胺具有腐蚀性，是易燃物质，闪点为28.6°C。它的LD50为0.71ml/kg（大鼠，经口）。不论吸入还是摄入均会使人中毒，吸入环己胺可能有致命危险。它很容易被皮肤吸收并带来不适感。

Cyclohexylamine is corrosive and flammable, with a flash point of 28.6 ° C. Its LD50 is 0.71ml/kg (rat, oral). Both inhalation and ingestion can cause poisoning, and inhalation of cyclohexylamine can be fatal. It is easily absorbed by the skin and causes discomfort.

作业现场通风良好；操作人员应穿工作服，戴口罩及防护手套，工作后沐浴更衣。

The work site is well ventilated; Operators should wear work clothes, masks, and protective gloves, and bathe and change clothes after work.

在使用环己胺作给水pH值调节剂时应注意如下诸点：

When using cyclohexylamine as a feedwater pH regulator, the following points should be noted:

①由于环己胺属于挥发性物质，不论在哪个部位加药，都可以使整个水汽系统中有胺，所以通常是将环己胺用水冲稀10%左右，加在脱氧器出口处。控制给水中环己胺过剩量为3.0~4.0mg/L；pH值过低(低于8.5)对环己胺处理不利。定期使用除垢剂可使设备无垢运行。

① As cyclohexylamine is a volatile substance, it can be added to the entire water vapor system regardless of where it is added. Therefore, cyclohexylamine is usually diluted to about 10% with water and added to the outlet of the deaerator. Control the excess amount of cyclohexylamine in feedwater to be 3.0~4.0mg/L; Low pH (below 8.5) is detrimental to cyclohexylamine treatment. Regular use of scale removers can make the equipment operate without scale.

②进行胺化处理后，环己胺进入锅炉后会随蒸汽挥发出来，随排汽进入凝汽器，由于环己胺不与水中Cu2+、Zn2+形成络离子，所以环己胺处理不会对黄铜材料发生腐蚀。

② After amination treatment, cyclohexylamine will volatilize with steam after entering the boiler and enter the condenser with exhaust steam. Since cyclohexylamine does not form complex ions with Cu2+and Zn2+in water, cyclohexylamine treatment will not cause corrosion to brass materials.

用环己胺调节给水pH的缺点是，药品高，水的处理费用比较大，所以采用环己胺处理应尽可能降低给水中的碳酸物含量。定期使用除垢剂可使设备无垢运行。更多相关产品事项就来我们网站http://www.jinhao360.com咨询！

The disadvantage of using cyclohexylamine to adjust the pH of feedwater is that the price of drugs is high and the cost of water treatment is relatively high. Therefore, using cyclohexylamine for treatment should minimize the content of carbonates in feedwater. Regular use of scale removers can make the equipment operate without scale.
