General Description

Heptafluoroisopropyl methyl ether is a synthetic, colorless liquid chemical compound known for its properties as a gaseous anesthetic. It is a fluoroether and belongs to the family of alkyl fluorides. Due to its molecular structure, it's highly stable and is generally considered to have low reactivity. This makes it ideal for use in situations where other volatile substances can pose a high risk. However, extended inhalation can cause health issues such as lung and eye irritation, and it may also exhibit environmental hazards. It's essential to handle it with utmost care, following proper safety guidelines.

Preparation method of isolated hydrofluoroether

The invention discloses a preparation method of isolated hydrofluoroether. The preparation method comprises the following steps: in the presence of inorganic fluoride and a co-catalyst, carrying out an alkylation reaction on perfluorinated epoxide and an alkylation reagent in an aprotic polar solvent to obtain the isolated hydrofluoroether. The main raw material perfluorinated epoxide can be prepared by epoxidation of perfluoro-olefin, the raw materials are simple and easy to obtain, the cost is lower than that of perfluorohexanone and perfluoroacyl fluoride compounds, the stability is good, the subsequent reaction is facilitated, and the quality can be ensured. The preparation method has the advantages that the reaction speed is high, the reaction time is short, the raw materials can be completely converted within 3-5 hours, the residual quantity of the raw material perfluorinated epoxy compound in the obtained crude product can be as low as 0.1% or below, and the reaction conversionrate is high. The content of the target product can reach 97% or above, the reaction selectivity is high, the byproducts are few, and the method is suitable for industrial application.

FLUOROALIPHATIC ESTERS OF FLUOROSULFONIC ACID. 2. REACTION BIS(FLUOROSULFATO)PERFLUOROALKANES WITH CESIUM FLUORIDE

2,3-Bis(fluorosulfato)perfluoroalkanes split under the action of CsF in the absence of solvents, giving a mixture of α-fluorosulfatoperfluoro ketones, perfluoroalkene sulfates, and perfluoro α-diketones.The occurence of these reactions in solutions results mainly in the formation of oxides of the corresponding fluoroolefins or products of their conversions.The reactions carried out are the first examples of nucleophilic substitution at a secondary carbon atom in a perfluorinated saturated chain.
