Sodium Acrylate is the acid form of Acrylic Acid (A191350); which is an antibacterial agent.

Sodium acrylate (NA) is a metal salt that can be made by an acid-base reaction of sodium hydroxide and acrylic acid. It can be used to produce poly(sodium acrylate) using bulk, solution, emulsion, and suspension polymerization processes. It results in the formation of a water soluble polymer that can be used in a variety of industrial and personal applications. It can be used in grain size optimization of iron oxide microparticles for potential applications in biological assays and chemical sensors. It can be used as a reducing and capping agent on gold nanoparticles that can be used in biological application.

Nonflammable

An aqueous solution of sodium acrylate is prepared from 216.2 g of acrylic acid (100%=3 mol), 262.8 g of NaOH (50%) and 497 g of water. 3.7 g of N-nitrosodiphenylamine and 3.7 g of 4-methoxyphenol are added to stabilize the solution. 12 g of the quaternary ammonium salt used in Example 1 are also added. 1,125 g (9 mol) of 1,4-dichlorobutene are run in at 90° C. 15.9 g of Na2CO3 are added after 1 hour and the mixture is left to react for a further 2 hours at 90° C. After phase separation, the organic layer is distilled under vacuum. 286.0 g (1.78 mol) of 4-chloro-2-butenyl acrylate (59.4% of the theoretical yield) are obtained. 641 g (5.13 mol) of dichlorobutene are recovered.
