简介
N-甲酰吗啉(N-formylmorpholine,简称NFM)是一种重要的有机溶剂和精细化工原料。常温下为无色透明液体。具有酰胺的化学性质,其水溶液在酸或碱存在的条件下易水解成吗啉和甲酸,水溶液呈弱碱性。
中文别名:4-吗啉甲醛;4-甲酰基吗啉;4-甲酰基吗啡啉
英文别名:4-morpholinecarbaldehyde; morpholine-4-carbaldehyde
CAS:4394-85-8
EINECS:224-518-3
分子量:115.1305
N-甲酰吗啉不仅具有选择性好、热稳定性和化学稳定性好、无毒、无腐蚀性等优点,而且由于其结构的特殊性,能与脂肪族烃类、芳烃以及水等互溶,具有良好的溶解萃取性能,因此被广泛应用于天然气及天然气凝析油、汽油、合成气、烟道气的脱硫,合成纤维、有机合成等工艺中;
同时由于N-甲酰吗啉溶解芳烃后,能大大降低芳烃的挥发度,提高芳烃与非芳烃之间的分离系数,因此被广泛应用于芳烃(如苯、甲苯、二甲苯等)与石蜡烃、丁烯、甲乙酮抽提等工艺中,可使精苯纯度高达99.99%,甲苯纯度达 99.7%,二甲苯纯度达 99.0%,并且溶剂消耗少、不需添加 pH 调节剂,具有对设备无腐蚀、节能、环境污染小等突出的优点。
另外,N-甲酰吗啉可以在聚酯塑料的发泡工业中用作催化剂,在精细化工领域用作甲酰化试剂,在医药工业用作药物合成反应的溶剂,并且都具有特别优良的性能,也是合成药物中间体的重要原料。

详细信息(英文):
Introduction to the
N - formyl morpholine (N - formylmorpholine (NFM) for short) is a kind of important organic solvents and fine chemical raw materials. Colorless transparent liquid under normal temperature. With amide chemistry, its aqueous solution in the presence of acid or alkali, easy hydrolysis into morpholine and formic acid, aqueous solution is weakly alkaline.
Chinese alias: 4 - morpholine formaldehyde; 4 - formyl morpholine; 4 - formyl morphine moiety
4 - morpholinecarbaldehyde; English nickname: Morpholine - 4 - carbaldehyde
CAS: 4394-85-8
EINECS: 224-518-3
Molecular weight: 115.1305
N - not only has good selectivity morpholine, good thermal stability and chemical stability, non-toxic, non-corrosive, and due to the particularity of its structure, with aliphatic hydrocarbons, aromatic hydrocarbons and water miscibility, good dissolving extraction performance, therefore they are widely used in natural gas and gas condensate oil, gasoline, synthesis gas, flue gas desulfurization, synthetic fiber, organic synthesis process.
As N - after dissolving aromatics morpholine, can greatly reduce the volatility of aromatics, improve between aromatics and aromatics separation factor, thus is widely applied to aromatic hydrocarbons such as benzene, toluene, xylene, etc.) and paraffin hydrocarbon, butene, methyl ethyl ketone extraction process, can make the pure benzene purity as high as 99.99%, the purity of toluene was 99.7%, and the purity of xylene was 99.0%, and less solvent consumption, does not need to add a pH regulator, has no corrosion to equipment, energy saving, environmental pollution and small outstanding advantages.
In addition, N - formyl morpholine can be used as a catalyst in the polyester plastic foam industry, in the field of fine chemicals used for formylation reagent, in the pharmaceutical industry used as a solvent, drug synthesis and have special excellent properties, but also an important raw material of synthetic drug intermediates.
