2,4-bis(2-hydroxyhexafluoro-2-propyl)fluorobenzene and method of preparing same |
| abstract |
By reacting fluorobenzene with hexafluoroacetone in the pressure of a Lewis acid catalyst, e.g. aluminum chloride, a novel compound 2,4-bis(2-hydroxyhexafluoro-2-propyl)fluorobenzene is formed at high yield with little formation of isomers. The novel compound is useful as a cross-linking agent for some polymers and also as a material of some polymers. |
