Ethylenesulfonic acid, also known as ethylene sulfonic acid or 2-hydroxyethanesulfonic acid, is a colorless, hygroscopic liquid with a strong acidic nature. It is a highly reactive compound that is primarily used in the production of ion exchange resins, surfactants, and water treatment chemicals. Ethylenesulfonic acid is a versatile chemical with a wide range of applications, including its use as a monomer in the production of polymers and copolymers, as a catalyst in chemical reactions, and as a stabilizer in the manufacturing of dyes and pigments. It is also used in the synthesis of pharmaceuticals and as a component in the development of electrolytes for fuel cells and batteries. Due to its corrosive and hazardous nature, ethylenesulfonic acid should be handled and stored with caution, following proper safety protocols and guidelines.

Check Digit Verification of cas no

The CAS Registry Mumber 1184-84-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,8 and 4 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1184-84:
(6*1)+(5*1)+(4*8)+(3*4)+(2*8)+(1*4)=75
75 % 10 = 5
So 1184-84-5 is a valid CAS Registry Number.

Preparation method of ethylene sulfate

-

Paragraph 0026-0029, (2021/09/29)

The invention provides a preparation method of ethylene sulfate, which comprises the following specific steps: 1) adding ethylene glycol disodium into a solvent, dropwise adding sulfonyl chloride at a certain temperature under the protection of nitrogen, reacting for a period of time, filtering, washing, and drying the solid to obtain sodium chloride; 2) combining the filtrate and the washing solution, washing to be neutral by using a sodium bicarbonate aqueous solution, and separating out an organic phase; and 3) drying the organic phase with anhydrous sodium sulfate, recovering the solvent under reduced pressure, recrystallizing the residue, and drying in vacuum to obtain ethylene sulfate. According to the invention, ethylene glycol disodium salt is used as a raw material and reacts with sulfonyl chloride in a solvent to synthesize ethylene sulfate. According to the method, the raw materials are easy to obtain, an expensive catalyst is not used, and the production cost is greatly reduced, so that the discharge of acid-containing wastewater and byproducts is fundamentally eliminated. The requirement of clean production is met; Meanwhile, the production cost is reduced, and great economic benefits and social benefits are achieved.
