Abstract
The invention relates to a process for producing 1,1,1,5,5,5-hexafluoroacetylacetone. This process includes (a) hydrolyzing a metal complex of 1,1,1,5,5,5-hexafluoroacetylacetone into a 1,1,1,5,5,5-hexafluoroacetylacetone hydrate; and (b) dehydrating the hydrate into the 1,1,1,5,5,5-hexafluoroacetylacetone with high purity from a material containing a metal complex of 1,1,1,5,5,5-hexafluoroacetylacetone.
Claims19
A process for producing a 1,1,1,5,5,5-hexafluoroacetylacetone hydrate, said process comprising hydrolyzing a metal complex comprising 1,1,1,5,5,5-hexafluoroacetylacetone into said hydrate by adding water and an acid to said metal complex, said water being in an amount sufficient for said hydrolyzing.
A process for producing 1,1,1,5,5,5-hexafluoroacetylacetone hydrate by adding water and an acid to said metal complex, said water being in an amount sufficient for said hydrolyzing;
- and dehydrating said hydrate into 1,1,1,5,5,5-hexafluoroacetylacetone.
A process for recovering 1,1,1,5,5,5-hexafluoroacetylacetone from a material comprising a metal complex of 1,1,1,5,5,5-hexafluoroacetylacetone, said process comprising:
- hydrolyzing said metal complex into a 1,1,1,5,5,5-hexafluoroacetylacetone hydrate by adding water and an acid to said metal complex, said water being in an amount sufficient for said hydrolyzing;
- and
- dehydrating said hydrate into said 1,1,1,5,5,5-hexafluoroacetylacetone.
A process for producing a 1,1,1,5,5,5-hexafluoroacetylacetone hydrate, said process comprising hydrolyzing a metal complex comprising 1,1,1,5,5,5-hexafluoroacetylacetone into said hydrate by adding water and an acid to said metal complex, said water being in an amount sufficient to make a reaction mixture into an aqueous solution, said reaction mixture comprising said metal complex, said water and said acid.
