Vinyl hydrogen sulphate, also known as vinyl hydrogen sulfite, is an organic compound with the chemical formula C2H4O3S. It is a colorless liquid that is soluble in water and has a pungent odor. vinyl hydrogen sulphate is primarily used as an intermediate in the production of various chemicals, such as vinyl sulfonic acid and vinyl sulfoxide. Vinyl hydrogen sulphate is synthesized by the reaction of acetylene with sulfur dioxide and water, followed by hydrolysis. It is an important precursor in the synthesis of various pharmaceuticals, dyes, and other specialty chemicals. Due to its reactivity, it is handled with care in industrial settings to prevent unwanted side reactions and to ensure safety.

Check Digit Verification of cas no

The CAS Registry Mumber 13401-80-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,4,0 and 1 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 13401-80:
(7*1)+(6*3)+(5*4)+(4*0)+(3*1)+(2*8)+(1*0)=64
64 % 10 = 4
So 13401-80-4 is a valid CAS Registry Number.

Preparation process of ethylene sulfate

-

Paragraph 0031-0046, (2021/10/30)

The invention relates to the technical field of lithium ion battery electrolyte additives, and particularly discloses a preparation process of ethylene sulfate. The preparation process comprises the steps of S1, taking ethylene glycol as an initial raw material, and performing exchange reaction with alkali metal alkoxide to generate alkali metal diol salt and lower alcohol; and S2, carrying out condensation reaction on the alkali metal diol salt and sulfuryl chloride or sulfuryl fluoride to generate ethylene sulfate and metal halide salt, and then refining to obtain ethylene sulfate. The method has the advantage of improving the product yield of ethylene sulfate.
