163702-07-6 Usage
Application
Methyl Perfluorobutyl Ether is a clear, colorless, low-odor, non-toxic, non-corrosive, non-flammable liquid substance with a chemical formula of C5H3F9O and a molecular weight of 250.06. Since it has low flammability, relatively low vapor pressure, low heat of vaporization, and low surface tension, it is considered to replace the chlorine-containing cleaning solvents such as 1,1,1-trichloroethane, CFC-113 (CF2ClCFCl2), and HCFC-141b (CH3CFCl2). Besides, it is a fluorinated ether solvent that is very compatible with many other ingredients, and is thought to have good sliding properties and serve as a good solvent in oil-based formulas.
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.
Chemical Properties
Clear colorless liquid
Uses
Different sources of media describe the Uses of 163702-07-6 differently. You can refer to the following data:
1. Nonafluorobutyl methyl ether (Methyl Nonafluorobutyl Ether, MFE) may be used to compose mixed-solvent electrolytes. Flash point, conductivity and NMR spectra of these solvent mixtures have been investigated.
2. Methoxyperfluorobutane can be used as a solvent: In the synthesis of various aryl fluoride derivatives via electrophilic fluorination of aryl and heteroaryl Grignard reagents. In grafting of fluorinated diblock copolymers onto silica particles.
General Description
consists of two inseparable isomers (CF3)2CFCF2OCH3 and CF3(CF2)3OCH3 with almost identical properties
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.
