環(huán)己胺是一種有機(jī)化合物，屬于脂肪族胺。純的環(huán)己胺是無色液體，但胺類物質(zhì)通常因混有雜質(zhì)而帶有顏色，環(huán)己胺也不例外。它帶有魚腥味，混溶于水，水溶液呈弱堿性，堿性比苯胺強(qiáng)。在有機(jī)合成中，環(huán)己胺是一種重要中間體。

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.

環(huán)己胺是合成其他有機(jī)物的重要中間體。例如，它是除草劑環(huán)嗪酮、次磺酰胺類硫化促進(jìn)劑的前體。次磺酰胺類促進(jìn)劑是黏液促進(jìn)劑、鎮(zhèn)痛藥、支氣管擴(kuò)張藥等藥物合成的重要組分。一些甜味劑通過環(huán)己胺合成得到，其中重要的是甜蜜素。另外，環(huán)己胺也是一種緩蝕劑。

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.

環(huán)己胺燃燒時分解，生成含有氮氧化物的有毒、腐蝕性煙霧。

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

氫氧化鉀廠家提醒您，環(huán)己胺是一種強(qiáng)堿。與酸發(fā)生劇烈反應(yīng)，并腐蝕。與強(qiáng)氧化劑急劇地發(fā)生反應(yīng)，產(chǎn)生著火的危險。其可浸蝕鋁、銅和鋅。

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.

環(huán)己胺具有腐蝕性，是易燃物質(zhì)，閃點(diǎn)為28.6°C。它的LD50為0.71ml/kg（大鼠，經(jīng)口）。不論吸入還是攝入均會使人中毒，吸入環(huán)己胺可能有致命危險。它很容易被皮膚吸收并帶來不適感。

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.

防護(hù)

protect

作業(yè)現(xiàn)場通風(fēng)良好；操作人員應(yīng)穿工作服，戴口罩及防護(hù)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.

在使用環(huán)己胺作給水pH值調(diào)節(jié)劑時應(yīng)注意如下諸點(diǎn)：

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

①由于環(huán)己胺屬于揮發(fā)性物質(zhì)，不論在哪個部位加藥，都可以使整個水汽系統(tǒng)中有胺，所以通常是將環(huán)己胺用水沖稀10%左右，加在脫氧器出口處?？刂平o水中環(huán)己胺過剩量為3.0~4.0mg/L；pH值過低(低于8.5)對環(huán)己胺處理不利。定期使用除垢劑可使設(shè)備無垢運(yùn)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進(jìn)行胺化處理后，環(huán)己胺進(jìn)入鍋爐后會隨蒸汽揮發(fā)出來，隨排汽進(jìn)入凝汽器，由于環(huán)己胺不與水中Cu2+、Zn2+形成絡(luò)離子，所以環(huán)己胺處理不會對黃銅材料發(fā)生腐蝕。

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.

用環(huán)己胺調(diào)節(jié)給水pH的缺點(diǎn)是，藥品高，水的處理費(fèi)用比較大，所以采用環(huán)己胺處理應(yīng)盡可能降低給水中的碳酸物含量。定期使用除垢劑可使設(shè)備無垢運(yùn)行。更多相關(guān)產(chǎn)品事項就來我們網(wǎng)站http://www.fahao168.com咨詢！

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.
