430-85-3 Usage
General Description
1,1-Dibromodifluoroethylene, also known as dibromodifluoroethylene or bromotrifluoroethene, is a colorless, non-flammable, and heavy liquid chemical compound. It is classified as a halogenated hydrocarbon and is primarily used as a monomer in the production of specialty polymers such as Teflon. 1,1-Dibromodifluoroethylene is highly reactive, toxic, and potentially carcinogenic, and it can also contribute to the depletion of the ozone layer. Due to its hazardous nature, the use and handling of this chemical are strictly regulated, and proper safety precautions must be taken when working with it.
Check Digit Verification of cas no
The CAS Registry Mumber 430-85-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,3 and 0 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 430-85:
(5*4)+(4*3)+(3*0)+(2*8)+(1*5)=53
53 % 10 = 3
So 430-85-3 is a valid CAS Registry Number.

Production process of ethyl bromodifluoroacetate
-
Paragraph 0025, (2020/12/30)
The invention discloses a production process of ethyl bromodifluoroacetate. The production process comprises the following steps: 1, bromination reaction; 2, elimination reaction; 3, oxidation reaction; 4, esterification reaction. Compared with other methods, the bromination addition reaction only needs to be carried out at normal pressure and under the catalysis of infrared light, so that the cost is saved compared with other catalysts, other impurities are not introduced, and the utilization rate of bromine is increased. The elimination reaction adopts a dropwise adding mode, so the reactionrate can be effectively controlled, and the flooding phenomenon which is easy to generate is avoided. The purity of the prepared finished product is greater than or equal to 99.0%, and the yield is greater than or equal to 80.0%.
