METHOD OF PREPARING (HALO)FLUOROHYDROCARBON, α- FLUOROETHERS, AND METHOD OF PREPARATION THEREOF |
| abstract |
FIELD: chemical industry. SUBSTANCE: method involves preparing [halo] fluorohydrocarbons used as cooling agents, foaming agents, solvents and propellents. The method comprises heating corresponding α-fluoroether in first phase at elevated temperature. α-fluoroethers are prepared by reacting non-enolizable aldehyde with fluorohydrogen to form intermediate compound and reacting the latter with alcohol or halogenating agent. The invention also describes novel α fluoroethers. The method is simple to put into practice. The present invention promotes search for suitable chlorofluorohydrocarbon substituents. EFFECT: higher efficiency. 29 cl, 7 dwg, 35 ex, 2 tbl |
