Description
METHYL NONAFLUOROBUTYL ETHER, also known as Methyl Perfluorobutyl Ether, is a clear, colorless, low-odor, non-toxic, non-corrosive, and non-flammable liquid substance. It consists of two inseparable isomers, (CF3)2CFCF2OCH3 and CF3(CF2)3OCH3, with almost identical properties. The chemical formula of METHYL NONAFLUOROBUTYL ETHER is C5H3F9O, and it has a molecular weight of 250.06. Due to its low flammability, relatively low vapor pressure, low heat of vaporization, and low surface tension, it is considered a suitable replacement for chlorine-containing cleaning solvents.
Uses
Used in Electrolyte Composition:
METHYL NONAFLUOROBUTYL ETHER is used as a component in mixed-solvent electrolytes. The flash point, conductivity, and NMR spectra of these solvent mixtures have been investigated.
Used in Chemical Synthesis:
METHYL NONAFLUOROBUTYL ETHER is used as a solvent in the synthesis of various aryl fluoride derivatives via electrophilic fluorination of aryl and heteroaryl Grignard reagents.
Used in Material Science:
METHYL NONAFLUOROBUTYL ETHER is used as a solvent in the grafting of fluorinated diblock copolymers onto silica particles.
Used in Cleaning Applications:
METHYL NONAFLUOROBUTYL ETHER is used as a cleaning solvent to replace chlorine-containing cleaning solvents such as 1,1,1-trichloroethane, CFC-113 (CF2ClCFCl2), and HCFC-141b (CH3CFCl2) due to its low flammability and environmental friendliness.
Used in Oil-Based Formulas:
METHYL NONAFLUOROBUTYL ETHER is used as a good solvent in oil-based formulas due to its compatibility with many other ingredients and its good sliding properties.
Preparation
Because methyl perfluorobutyl ether contains perfluoroalkyl group (Rf) on one side and alkyl group (R) on the other side of ether linkage, it cannot be synthesized by selective partial fluorination of its hydrocarbon precursors. Instead, they may be prepared by coupling reactions of two reactants having Rf and R, coupling reactions of two reactants having Rf and R, respectively.
Check Digit Verification of cas no
The CAS Registry Mumber 163702-07-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,3,7,0 and 2 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 163702-07:
(8*1)+(7*6)+(6*3)+(5*7)+(4*0)+(3*2)+(2*0)+(1*7)=116
116 % 10 = 6
So 163702-07-6 is a valid CAS Registry Number.

Method for preparing fluorine-containing ether
-
Paragraph 0086-0087, (2019/07/29)
The invention relates to a 'method for preparing fluorine-containing ether', and belongs to the field of chemical synthesis. The method comprises the steps that under a nitrile solvent condition, carbonyl fluoride, trifluoroacetyl fluoride, pentafluoropropionyl fluoride, heptafluoro-n-butyryl fluoride, heptafluoro-iso-butyryl fluoride and other acyl fluorides are taken as raw materials to have anaddition reaction with metal fluorides to obtain perfluoroalkoxide, then under water catalysis, the perfluoroalkoxide and a low-toxic or even non-toxic harmless alkylating agent are subjected to an alkylation reaction to obtain the fluorine-containing ether. The method for preparing the fluorine-containing ether has the advantages that not only is the reaction condition mild, the yield of the fluorine-containing ether is high, but also the low-toxic or even non-toxic harmless alkylating agent is taken as a safe alkylation agent, the process is safe and reliable, and effective separation can beperformed by an ordinary distillation means in the industry.
