It is possible by this method to produce the hexafluoroisopropanol with a short reaction time and a high conversion. Therefore, it is possible to particularly advantageously produce fluoromethyl hexafluoroisopropyl ether (sevoflurane) by using the hexafluoroisopropanol produced by the method."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for producing hexafluoroisopropanol and fluoromethyl hexafluoroisopropyl ether (sevoflurane)","description":"Disclosed is a method for producing a hexafluoroisopropanol, including the steps of (a) purifying a mixture containing hexafluoroacetone and at least 1,1,1-trifluoro-2,2-dichloroethane as an impurity,","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9637435","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
