Process For The Preparation Of SODIUM METHALLYL SULFONATE:

Sodium Methallyl Sulfonate can be used in Polycarboxylate Superplasticizer(PC) as the chain transfer agent
Reaction of methallyl chloride (MAC) containing isocrotyl chloride (ICC) with aqueous sodium sulfite solution in an emulsion at 30°-80° C and pH 7-11, maintained constant during the reaction by metered addition of sodium hydroxide solution is done in a two-step process, in the first step of which a mixture enriched in ICC and depleted in MAC from a preceding reaction batch and/or the second reaction step as excess organic residual phase, is reacted with an excess of concentrated sulfite solution until the MAC has been practically completely consumed
In the second step of which the reaction solution remaining after separating the unreacted ICC by distillation is reacted with a technical MAC/ICC mixture containing an excess of MAC until sulfite has been practically completely consumed.
Thereafter, the excess organic residual phase is recycled to the first step after distillative separation.
The MAC is preferably added in 10-40% excess in the second step.

Sodium Methallyl Sulfonate is the sodium salt of 2-hydroxyethane sulfonic acid (isethionic acid)
Sodium Methallyl Sulfonate is used as a hydrophilic head group in washing-active surfactants, known as isethionates (acyloxyethanesulfonates) due to its strong polarity and resistance to multivalent ions.
Sodium Methallyl Sulfonate is being studied as a high production volume chemical in the "High Production Volume (HPV) Chemical Challenge Program" of the US Environmental Protection Ministry EPA.

Production:
Sodium Methallyl Sulfonate is formed by the reaction of ethylene oxide with sodium hydrogen sulfite in aqueous solution
To avoid contamination and suppress the formation of by-products (which are difficult to remove) the reaction must be performed under careful control of mass ratios and process conditions.
Excess sulfite (SO32−) or bisulfite (HSO3−) lead to an unpleasant odor of the downstream product, higher levels of ethylene glycol or glycol ethers (formed by the hydrolysis and ethoxylation of ethylene oxide) give hygroscopic and greasy surfactants.

Concentrated ethylene glycol-containing Sodium Methallyl Sulfonate solutions can subsequently mostly be freed from ethylene glycol by continuous extraction with e.g. isopropanol (<0.5%).
Therefore, in the continuous industrial process an aqueous sodium hydrogen sulfite solution is prepared in a first reactor by mixing a sodium hydroxide solution and sulfur dioxide.
In a second reactor the sodium hydrogen sulfite solution is mixed with a slight excess of ethylene oxide to obtain sodium 2-hydroxyethyl sulfonate in almost quantitative yields at elevated temperature and pressure with a precise control of pH.
The reaction has to take place under the exclusion of oxygen and under precise control of the stoichiometry of the reactants, the temperature, the pH and the throughput.

Properties:
Solid Sodium Methallyl Sulfonate is as;
-colorless
-free-flowing
-non-hygroscopic solid, which dissolves readily in water and has good biodegradability.
Due to the method of synthesis samples often contain traces of sodium sulfite or sodium hydrogen sulfite causing aqueous solution to possesses a mildly alkaline pH of about 10.
