Title:
PROCESS FOR PREPARING LINEAR PERFLUOROOLEFIN DERIVATIVE
Document Type and Number:
Japanese Patent JPS53124207
Kind Code:
A
Abstract:
To prepare surface-active compounds, straight-chain perfluoroolefins or mixtures thereof are reacted with nucleophilic substances. The straight-chain perfluoroolefins having 5 to 20 carbon atoms contain terminal and internal [lacuna] and optionally several double bonds in the molecule. The reaction is carried out in a solvent at normal pressure or at elevated pressure and at temperatures from 20 to 150 DEG C. The compounds of the straight-chain perfluoroolefins prepared have surface-active properties, including hydrophobic/oleophobic properties, or are suitable as intermediates for obtaining compounds of this type. They are used in electrotechnology as additives in chroming baths, as highly effective additives in fire extinguishers, as mould release agents, antifouling agents, flow agents, emulsifiers and as finishing agents for textiles, leather and paper.
