乙氧基化壬基酚磺基琥珀酸半酯二钠盐 (CAS No.9040-38-4)
- 中文别名
- 壬基酚聚氧乙烯醚磺基琥珀酸半酯二钠盐；壬基酚聚氧乙烯醚磺基丁二酸单酯二钠盐
- 英文名称
- Ethoxylated Nonylphenol Sulfosuccinate Half-Ester Disodium Salt
- 分子式
- C38H64O16Na2S
- 所属类别
- 有机无机原料
- 物化性质
- 分子量为854.96。无色至浅黄色液体，1%水溶液pH值为5.5～7.0，比重(25℃)为1.060～1.090 g/cm³，粘度(25℃)小于200 cP。由于分子中含苯环和环氧乙烷链，在水中不规则弯曲伸展，空间位阻大；磺酸基和羧酸基亲水性强，体系电荷密度大、分布广，因此耐电解质和机械稳定性优秀。

Product Name:Ethoxylated Nonylphenol Sulfosuccinate Half-Ester Disodium Salt
English Name:Ethoxylated Nonylphenol Sulfosuccinate Half-Ester Disodium Salt
CAS No.:9040-38-4
Aliases:Disodium Nonylphenol Ethoxylate Sulfosuccinate, Nonylphenol Polyoxyethylene Ether Sulfosuccinate Disodium Salt
Molecular Formula:C38H64O16Na2S
Physical Properties:Molecular weight is 854.96. It appears as a colorless to light yellow liquid. The pH of a 1% aqueous solution is 5.5–7.0, specific gravity (25°C) is 1.060–1.090 g/cm³, and viscosity (25°C) is less than 200 cP. Due to the presence of benzene ring and ethylene oxide chains, it exhibits large steric hindrance in water; the sulfonate and carboxylate groups provide strong hydrophilicity, resulting in high and widely distributed charge density, thus excellent resistance to electrolytes and mechanical stability.
Uses:Widely used in metalworking, printing inks, foamed cement, leather tanning, dyes, coatings, and adhesives. In emulsion polymerization, it is particularly suitable for the synthesis of vinyl acetate, vinyl acetate-acrylic, pure acrylic, styrene-acrylic, and EVA-based emulsions, yielding resins with fine particles, low coagulum, good freeze-thaw stability, and transparent glossy films. It also serves as a latex particle size modifier and post-additive stabilizer without affecting the crosslinking efficiency of self-crosslinking monomers such as N-methylol acrylamide.
Technical Specifications:
Appearance (25°C): colorless to light yellow liquid
Active content: 25-26% (wt%)
Solids content: 32-35% (wt%)
pH (1% aqueous solution): 5.5-7.0
Viscosity (25°C): <200 cP
