1561-92-8 Usage

Uses

2-Methyl-2-propene-1-sulfonic acid sodium salt was used as anionic monomer to investigate the effect of different cationic or anionic moieties in acrylonitrile-based copolymers on the interaction with fibroblasts. It was used to reduce the homopolymerization during graft copolymerization of methyl methacrylate with water-emulsified solution onto preirradiated jute fiber.

Flammability and Explosibility

Flammable

Synthesis

The synthesis of?2-METHYL-2-PROPENE-1-SULFONIC ACID SODIUM SALT is as follows:The neutralization was carried out with sodium carbonate to pH 7. The neutralized filtrate was evaporated under reduced pressure (20 mmHg) to remove water and to obtain 46.5 g of white crystalline sodium methallyl sulfonate. The product was identified with a standard sample by IR spectrum. The purity of the product was 95.5% and the yield 95%.

Check Digit Verification of cas no

The CAS Registry Mumber 1561-92-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,6 and 1 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1561-92:
(6*1)+(5*5)+(4*6)+(3*1)+(2*9)+(1*2)=78
78 % 10 = 8
So 1561-92-8 is a valid CAS Registry Number.

Olefination with Sulfonyl Halides and Esters: E-Selective Synthesis of Alkenes from Semistabilized Carbanion Precursors

Górski, Bartosz,Basiak, Dariusz,Talko, Alicja,Basak, Tymoteusz,Mazurek, Tomasz,Barbasiewicz, Micha?

supporting information, p. 1774 - 1784 (2018/04/27)

Carbanions of sulfonyl halides and activated sulfonates add to carbonyl compounds, and so-formed aldol-type adducts spontaneously fragment into olefins. This transformation mimics the one-pot Julia olefination with (hetero)aryl sulfones, but the mechanism of fragmentation involves a four-membered intermediate, typical for reactivity of phosphorus reagents. Moreover, in contrast to the reactions of sulfones, sulfonates of fluorinated alcohols (TFE and HFI) produce byproducts that are easily removed during workup. In our report, we focus on reactions of unstabilized and semistabilized carbanion precursors: alkylsulfonates, and allyl- and benzylsulfonates, respectively. In particular for semistabilized systems, olefins were synthesized as predominant E isomers in good yields. The presented studies reveal that optimal reaction conditions, including the type of base and alcohol groups of the sulfonates, are different depending on stabilization of the carbanion precursors and structure of the carbonyl substrates. The practical synthetic guide is supplemented with a discussion of the mechanism, based on reactivity studies of intermediates and identification of side-products.

Process for the preparation of methallyl sulfonic acid and its salts

-

, (2008/06/13)

A process for the preparation of methallyl sulfonic acid and its salt which process comprises the reaction of isobutylene with a complex of sulfur trioxide to form methallyl sulfonic acid and, if desired, neutralization of the formed acid with an alkaline compound to obtain its salt. The sulfur trioxide complex is prepared by a reaction of sulfur trioxide with a mono-alkyl substituted amide of an aliphatic carboxylic acid, which has a tertiary carbon atom bonded directly to the nitrogen atom thereof.
