1644-11-7 Usage

General Description

2-(Perfluoropropoxy)perfluoropropyl trifluorovinyl ether is a fluorinated compound with the chemical formula C6F13O2. It is a colorless liquid at room temperature and is commonly used as a monomer in the production of fluoropolymer coatings and films. It is known for its high thermal and chemical stability, as well as its resistance to solvents and harsh environmental conditions. This makes it suitable for a wide range of industrial applications, including in the aerospace, automotive, and electronics industries. Additionally, it is also used as a specialty chemical in the production of high-performance materials and as a processing aid in the manufacturing of other fluorinated products.

Check Digit Verification of cas no

The CAS Registry Mumber 1644-11-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,4 and 4 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1644-11:
(6*1)+(5*6)+(4*4)+(3*4)+(2*1)+(1*1)=67
67 % 10 = 7
So 1644-11-7 is a valid CAS Registry Number.

Reaction of 1,1,2-trifluoro-2-hexafluoro-2′-(heptafluoropropoxy)-propoxyethylene with amines or alcohols

Furin, Georgii G.,Pressman, Luiza S.,Pokrovsky, Leonid M.,Krysin, Aleksei P.,Chi, Ki-Whan

, p. 13 - 24 (2000)

Reaction between 1,1,2-trifluoro-2-hexafluoro-2′-(heptafluoropropoxy)-propoxyethylene and secondary amines (dimethylamine, diethylamine, dibutylamine, pyrrolidine, piperidine, morpholine) leads either to perfluoro-2-propoxy-3(1H′)-ethoxy-2″-alkoxypropanes - the addition products to the double bond - or to an N,N-dialkylamide of α-substituted fluoroacetic acid depending on the solvent used and the following work-up of the crude product. With primary amines (propylamine, butylamine, monoethanolamine), fluorine-containing imines or N-alkylamides of the α-substituted fluoroacetic acid (as a mixture of diastereomers) were obtained. The use of diethanolamine produces 2-{fluoro-2[hexafluoro-2′-(heptafluoropropoxy)-propoxy]-methyl}-4,5,7,8- tetrahydro-[1.6.3]dioxasozine. Reaction of 1,1,2-trifluoro-2′-hexafluoro-2′-(heptafluoropropoxy)- propoxyethylene with alcohols (methanol, ethanol, β,β,β-trifluoroethanol, 2-methoxyethanol, 2-ethoxyethanol, iso-propanol, butanol and pentafluorophenol) in the presence of KOH in tetrahydrofuran (sulfolane, DMSO, acetonitrile) or sodium alkoxide in an alcoholic medium yields only the corresponding ethers as a mixture of diastereomers. Treatment of ethyleneglycol, glycerine, pentaerythritol, triethanolamine, 2-(2-hydroxyethylsulphanyl) ethanol, 4-(2-hydroxyethyl) phenol with 1,1,2-trifluoro-2′-(heptafluoropropoxy)-2-hexafluoropropoxyethylene provides the addition products to all OH groups if the reaction is carried out in DMSO, sulfolane or acetonitrile. However, the use of THF as the solvent leads to the formation of α-substituted tetrahydrofuran together with the formation of ethers. The initial perfluoro(propoxypropoxy) olefin can be hydrolyzed in the alkaline media to give fluoro-[hexafluoro-2-(heptafluoropropoxy)propoxy]acetic acid.

A fluorinated alkyl vinyl ether of preparation method

-

Paragraph 0035; 0036, (2017/02/24)

The invention discloses a fluoroalkylvinyl ether preparation method. The method comprises the following steps: carrying out a film forming reaction on perfluoroalkyloxypropionyl fluoride by a salt forming agent under the action of an aprotic alcohol ether catalyst at 20-80DEG C, and carrying out a decarboxylation reaction at 110-150DEG C to prepare corresponding fluoroalkylvinyl ether. The preparation method has the advantages of high raw material conversion rate, simple process, no need of a solvent, and the like.
