名稱：胺填充柱

型號：HH-SJNH2

規(guī)格：2m*3mm，80-100目

使用溫度：80°C

1.出峰順序：甲胺，二甲胺，三甲胺

2.出峰順序：三甲胺，二甲胺，一甲胺

3.出峰順序：三甲胺，一甲胺，二甲胺

一甲胺(methylamine，ch3nh2)、二甲胺[dimethylamine，(ch3)2nh]和三甲胺[trimethylamine，(ch3)3n]均為無色、有難聞的魚腥惡臭味、屬中等急性毒性的物質(zhì)，水溶液均為中強(qiáng)堿性，在空氣中爆炸極限一甲胺為4.9％～20.7％，二甲胺為2.8％～14.4％，三甲胺為2％～11.6％，20℃時的蒸汽壓為173.9kpa(1307.2mmhg)。由于它們沸點(diǎn)低，蒸汽壓高，在生產(chǎn)和使用時易揮發(fā)。一甲胺、二甲胺和三甲胺是重要的有機(jī)化工原料，被用作合成很多其他化合物的原材料，每年大約能生產(chǎn)上億千克，廣泛引用于國民經(jīng)濟(jì)各行業(yè)，是農(nóng)藥、醫(yī)藥、合成染料、合成樹脂、化學(xué)纖維、照相材料、溶劑、炸藥、高能燃料、表面活性劑及硫化促進(jìn)劑的主要原料。有機(jī)胺類化合物對健康和環(huán)境存在危害，容易對人體的眼睛、皮膚、粘膜等產(chǎn)生危害，人體組織吸收某些胺類化合物后還有可能致癌。例如，皮膚接觸液態(tài)二甲胺可引起壞死，眼睛接觸可引起角膜損失、渾濁；二甲胺長期被人體吸收會使骨髓染色體結(jié)構(gòu)出現(xiàn)異常；三乙胺對呼吸道有強(qiáng)烈的刺激性，吸入后可引起肺水腫甚死亡，口服腐蝕口腔、食道及胃，眼及皮膚接觸可引起化學(xué)性灼傷。

Name: Amine Packed Column

Model: HH-SJNH2

Specifications: 2m*3mm, 80-100 mesh

Operating temperature: 80°C



1. Peak order: methylamine, dimethylamine, trimethylamine

2. Peak sequence: trimethylamine, dimethylamine, monomethylamine

3. Peak order: trimethylamine, monomethylamine, dimethylamine



Monomethylamine (ch3nh2), dimethylamine [dimethylamine, (ch3)2nh] and trimethylamine [trimethylamine, (ch3)3n] are colorless, have an unpleasant fishy odor, and are of moderate acute toxicity In the air, the explosion limit is 4.9% to 20.7% for monomethylamine, 2.8% to 14.4% for dimethylamine, and 2% to 11.6% for trimethylamine. The steam at 20°C The pressure is 173.9kpa (1307.2mmhg). Due to their low boiling point and high vapor pressure, they are volatile during production and use. Monomethylamine, dimethylamine and trimethylamine are important organic chemical raw materials, which are used as raw materials for synthesizing many other compounds. about 100 million kilograms can be produced every year. They are widely used in various industries of the national economy. They are pesticides, medicines, synthetic dyes , Synthetic resins, chemical fibers, photographic materials, solvents, explosives, high-energy fuels, surfactants and the main raw materials for vulcanization accelerators. Organic amine compounds are harmful to health and the environment, and are easy to cause harm to human eyes, skin, mucous membranes, etc., and human tissues may cause cancer after absorbing some amine compounds. For example, skin contact with liquid dimethylamine can cause necrosis, and eye contact can cause corneal loss and turbidity; long-term absorption of dimethylamine by the human body can cause abnormal bone marrow chromosomal structure; It can cause pulmonary edema and even death. Oral corrosion can cause chemical burns to the mouth, esophagus and stomach. Contact with eyes and skin can cause chemical burns.
