甲胺水溶液中组分含量的测定 详细信息：

名称：胺填充柱

型号：HH-SJNH2

规格：2m*3mm，80-100目

使用温度：80°C

1.出峰顺序：甲胺，二甲胺，三甲胺

2.出峰顺序：三甲胺，二甲胺，一甲胺

3.出峰顺序：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]均为无色、有难闻的鱼腥恶臭味、属中等急性毒性的物质，水溶液均为中强碱性，在空气中爆炸极限一甲胺为4.9％～20.7％，二甲胺为2.8％～14.4％，三甲胺为2％～11.6％，20℃时的蒸汽压为173.9kpa(1307.2mmhg)。由于它们沸点低，蒸汽压高，在生产和使用时易挥发。一甲胺、二甲胺和三甲胺是重要的有机化工原料，被用作合成很多其他化合物的原材料，每年大约能生产上亿千克，广泛引用于国民经济各行业，是农药、医药、合成染料、合成树脂、化学纤维、照相材料、溶剂、炸药、高能燃料、表面活性剂及硫化促进剂的主要原料。有机胺类化合物对健康和环境存在危害，容易对人体的眼睛、皮肤、粘膜等产生危害，人体组织吸收某些胺类化合物后还有可能致癌。例如，皮肤接触液态二甲胺可引起坏死，眼睛接触可引起角膜损失、浑浊；二甲胺长期被人体吸收会使骨髓染色体结构出现异常；三乙胺对呼吸道有强烈的刺激性，吸入后可引起肺水肿甚死亡，口服腐蚀口腔、食道及胃，眼及皮肤接触可引起化学性灼伤。

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.
