Aplicaciones

Morpholine is a common additive for pH adjustment in both fossil fuel and nuclear power plant steam systems. It is widely used in organic synthesis as a building block in the preparation of the antibiotic linezolid, the anticancer agent gefitinib and the analgesic dextromoramide. It is also used as a solvent in chemical reactions and in the preparation of enamines. Further, it serves as a chemical emulsifier in the process of waxing fruit.

Notas

Hygroscopic. Incompatible with strong oxidizing agents.
