N-formylmorpholine, referred to as NFM
Alias: 4-morpholinecarbaldehyde; morpholine-4-carbaldehyde
CAS: 4394-85-8
EINECS: 224-518-3
Molecular weight: 115.1305
N-formylmorpholine not only has good selectivity, thermal stability and chemical stability It has the advantages of good, non-toxic, non-corrosive, etc., and due to the particularity of its structure, it can be miscible with aliphatic hydrocarbons, aromatic hydrocarbons and water, and has good dissolution and extraction performance, so it is widely used in natural gas and natural gas condensate oil. , gasoline, syngas, flue gas desulfurization, synthetic fibers, organic synthesis and other processes;
at the same time, after N-formylmorpholine dissolves aromatics, it can greatly reduce the volatility of aromatics and improve the separation coefficient between aromatics and non-aromatics. Therefore, It is widely used in the extraction of aromatic hydrocarbons (such as benzene, toluene, xylene, etc.) and paraffin hydrocarbons, butene, methyl ethyl ketone, etc., which can make the purity of refined benzene up to 99.99%, the purity of toluene up to 99.7%, and the purity of xylene. Up to 99.0% , and less solvent consumption, no need to add pH adjuster, with outstanding advantages such as no corrosion to equipment, energy saving, and less environmental pollution.
In addition, N-formylmorpholine can be used as a catalyst in the foaming industry of polyester plastics, as a formylation reagent in the fine chemical industry, and as a solvent for drug synthesis reactions in the pharmaceutical industry. An important raw material for the synthesis of pharmaceutical intermediates.
