65605-70-1 Usage
Description
Perfluoroalkylethyl acrylate is an important monomer for the synthesis of fluoropolymers, and is also a key step in the synthesis of fluorine-containing finishing agents.
Uses
Perfluoroalkylethyl acrylate is a polymer that can be used as an important monomer for the synthesis of fluoropolymers.
Synthesis
Using p-toluenesulfonic acid as catalyst, Perfluoroalkylethyl acrylate was synthesized.Experimental procedure: Add polyfluoroalcohol, acrylic acid, and solvent to a dry four-necked flask equipped with a stirrer, reflux condenser, thermometer and water separator, and add p-toluenesulfonic acid after stirring evenly. The temperature is raised to reflux, and the reaction is carried out for a period of time until the water collected in the water separator reaches the theoretical amount. The solvent and excess acrylic acid were evaporated, and 5% (mass fraction) sodium bicarbonate solution was added dropwise to the cooled reaction solution until the pH was about 7-8. Filtration yielded a milky white solid. After vacuum drying, vacuum distillation was performed to collect Perfluoroalkylethyl acrylate at 82-134°C under 199.3Pa.
Check Digit Verification of cas no
The CAS Registry Mumber 65605-70-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,6,0 and 5 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 65605-70:
(7*6)+(6*5)+(5*6)+(4*0)+(3*5)+(2*7)+(1*0)=131
131 % 10 = 1
So 65605-70-1 is a valid CAS Registry Number.
