Potassium perfluoroheptanoate is employed as a surfactant in the production of foams, contributing to their stability and performance in various applications.
Used in the Fire-Extinguishing Industry:
As a component in fire-extinguishing agents, Potassium perfluoroheptanoate aids in the suppression of fires by reducing the surface tension of water, allowing it to spread more effectively over the fire source.
Used in the Photographic Films Industry:
In the production of photographic films, Potassium perfluoroheptanoate is used as a wetting agent to ensure even distribution of chemicals and to improve the quality of the film.
Used in the Cleaning and Coating Products Industry:
Potassium perfluoroheptanoate is used in the formulation of high-performance cleaning and coating products, enhancing their effectiveness and durability.
However, due to its potential environmental and health concerns, there is ongoing scrutiny and regulation around the use and disposal of Potassium perfluoroheptanoate and other perfluorinated compounds, necessitating careful consideration of its applications and potential impacts.
Check Digit Verification of cas no
The CAS Registry Mumber 21049-36-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,0,4 and 9 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 21049-36:
(7*2)+(6*1)+(5*0)+(4*4)+(3*9)+(2*3)+(1*6)=75
75 % 10 = 5
So 21049-36-5 is a valid CAS Registry Number.

Production process of fluorine-containing carboxylic acid
-
Paragraph 0043-0044, (2020/07/13)
The invention discloses a production process of fluorine-containing carboxylic acid. The method comprises the following steps: by taking fluorine-containing olefin as a raw material, carrying out an oxidation reaction to obtain fluorine-containing carboxylate, reacting the fluorine-containing carboxylate with an acylating chlorination reagent to obtain a corresponding mixture of fluorine-containing acyl chloride and fluorine-containing acid anhydride, and hydrolyzing and drying the mixture of fluorine-containing acyl chloride and fluorine-containing acid anhydride to prepare the high-purity fluorine-containing carboxylic acid. The method provided by the invention is suitable for post-treatment of fluorine-containing carboxylic acid prepared by a fluorine-containing olefin (monoolefine, diene, cycloolefin and the like) oxidation method, replaces the traditional strong acid acidification and ether continuous extraction process, and is simpler, more convenient and more applicable; the purity of the fluorine-containing carboxylic acid prepared by the method can reach 98% or above.
