아크릴산 나트륨 화학적 특성, 용도, 생산

화학적 성질
Colorless or light yellow viscous liquid, non-toxic, weakly alkaline, insoluble in organic solvents such as ethanol, acetone, etc., easily soluble in water and aqueous sodium hydroxide, but in aqueous solutions such as calcium hydroxide, magnesium hydroxide, etc., with the increase in the number of alkaline-earth metal ions, the first to dissolve and then precipitate.
용도
Sodium Acrylate (SA) is a sodium salt of acrylic acid with antibacterial properties. Sodium polyacrylate is a sodium salt of a polymer consisting of acrylic acid, methacrylic acid or one of their simple esters. SA can be used in tuning the grain size of iron oxide microparticles for potential applications in biological assaying and in chemical sensors. Additionally, it acts as a reducing and capping agent for gold nanoparticles, beneficial for various biological applications.
일반 설명
Sodium acrylate (SA) is a metal salt that can be prepared by an acid-base reaction between sodium hydroxide and acrylic acid. It can be used in the preparation of poly(sodium acrylate) using bulk, solution, emulsion, and suspension polymerization techniques. It results in the formation of a water soluble polymer that can be used in a variety of industries and personal care applications.
Synthesis
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.
