Sodium allylsulfonate Usage And Synthesis

Description

Sodium allylsulfonate (SAS) is a white powder with the formula C₃H₅NaO₃S. The electroplated nickel intermediate sodium allylsulfonate (35% aqueous solution) is directly synthesized with allyl chloride and sodium sulfite in the aqueous phase. Sodium allysulfonate is used as a basic brightener in nickel electroplating baths. it is also used as pharmaceutical intermediates. Sodium allylsulfonate is a chemical which is used as nickel plating bathadditive.

Chemical Properties

White to Almost white powder to crystal.

Uses

Sodium Allylsulfonate is used as a brightener for nickel electroplating as well as in the dyeing of acryilic fibers.

Uses

Sodium allylsulfonate ( ALS 25% ) used as one of the primary component in Nickel brightener formulations. Sodium allylsulfonate ( ALS 25% ) is a co-monomer of the polymers especially for functional acrylic fibers(dying betterment and heat resistance). It is used in chain transfer agent. Sodium allylsulfonate 35% is used as a brightener for nickel electroplating, the general dosage is 0.1～0.2g/L. It can also used as a dyesite monomer in acrylic fiber, and as a performance monomer in synthetic polymer applications. Sodium allylsulfonate can be used as various reactive emulsifiers, flocculants, water reducers for commercial concrete, and so on.

Preparation

At 50 °C, sodium metabisulfite dissolved in deionized water and stirred until sodium metabisulfite is completely dissolved. Add triethylbenzyl chloride to the sodium metabisulfite solution ammonium and polymerization inhibitor p-tert-butyl catechol. After stirring and mixing uniformly, a sodium metabisulfite mixture is obtained. The sodium metabisulfite mixture is passed through three high-precision plungers, sodium hydroxide solution, and allyl chloride. The metering pump is simultaneously pumped into the microchannel reactor for reaction. Adjust the reaction temperature in the microchannel reactor to 40 ° C and adjust the back pressure valve to make the pressure of the microchannel reactor 0.3 MP. The crude product is filtered through a fine filter, and sodium allylsulfonate is collected.

Hazard

Sodium allylsulfonate may cause eye irritation and damage to the targeted central nervous system. The main risk of industrial exposure to allyl chloride is damage to the peripheral nervous system. Polyneuropathy is considered to be the main clinical manifestation of chronic allyl chloride exposure.

Flammability and Explosibility

Non flammable

storage

Store in a cool, dry, well-ventilated area away from acids and oxidizing agents. Keep container closed when not in use and protect from physical damage.
