Documented Uses

• ... HFC 227ea can be used as ... /a propellant/ in medicinal aerosols instead of CFC 114.
• HFC 227ea is being developed as a CFC replacement in refrigerants, high temperature heat pumps, air-conditioning systems; as a fire suppressant; and for pharmaceutical aerosols and metered-dose inhalers.
• Propellants for medical sprays including: MDIs (Metered Dose Inhalers) also known as pharmaceutical aerosols or asthma sprays for the treatment of asthma, COPD (Chronic Obstructive Pulmonary Disorder) and respiratory infections; nasal sprays for the treatment of allergic rhinitis; foam sprays; oral and topical sprays (e.g. nerve sensitization, tooth vitality, pain relaxation).
• Propellants, non-motive (blowing agents)
• Monohydroperfluoroalkanes can be obtained by adding hydrogen fluoride to perfluoroalkenes (e.g., CF3-CHF-CF3, HFC 227ea) or by decarboxylation of perfluorocarboxylates in the presence of proton donors.
