Description

4-Formylmorpholine is an excellent non-protonic solvent. It is widely used as a solvent and extractant for aromatics. It is used as a detergent for acid gases. In the field of organic synthesis, it can be used to prepare labelled 14C, 4-(trifluoromethyl)morpholine, 3-alkyl-2-chloro-5,6-dihydrobenzaldehyde, triple-biphenyldialdehyde and phenylpropargyl aldehyde. It plays an important role in the desulphurisation of natural gas, syngas, flue gas and petrol.

Uses

4-Formylmorpholine is widely used as a solvent and extracting agent for aromatics. It is used as a scrubbing agent for acidic gases. It is employed in the preparation of adenine hydrochloride labeled with 14C, 4-(trifluoromethyl)morpholine, 3-alkyl-2-chloro-5,6-dihydrobenzaldehyde and terphenyl dialdehyde. It plays an important role in the desulfurization of natural gas, synthetic gas, flue gas and gasoline.

General Description

Treatment of 4-formylmorpholine with sulphur tetrafluoride in the presence of potassium fluoride gives 4-(trifluoromethyl)morpholine in excellent yields. 4-Formylmorpholine reacts with series of 2-alkyl-2-cyclohexen-1-ones in the presence of POCl₃ to give the corresponding 3-alkyl-2-chloro-5,6-dihydrobenzaldehydes and allylic alcohols (by-product).

Flammability and Explosibility
