Description

9,10-Dichlorostearicacid is a chlorinated derivative of stearic acid, characterized by the substitution of chlorine atoms at the 9 and 10 positions of the carbon chain. This functionalization imparts unique chemical reactivity, making it a valuable intermediate for synthesizing specialized surfactants, lubricant additives, and polymer modifiers. It is primarily utilized by research and development chemists, as well as industrial manufacturers in the specialty chemical, agrochemical, and advanced materials sectors seeking to modify surface properties or introduce specific functionalities into their products.

Application

• Chemical Intermediate: Serves as a key building block for the synthesis of chlorinated surfactants, emulsifiers, and corrosion inhibitors.
• Lubricant & Fuel Additive Precursor: Used in the production of additives that enhance extreme pressure performance and anti-wear properties in industrial lubricants and metalworking fluids.
• Polymer Modification: Acts as a monomer or modifier for introducing chlorine functionality into polymers to alter flame retardancy, adhesion, or compatibility.
• Agrochemical Synthesis: Employed in the research and development of chlorinated active ingredients or adjuvants for crop protection formulations.
• Research & Development: A valuable reagent in organic synthesis for studying chlorination reactions and developing novel specialty chemicals.
• Surface Active Agent Production: Used to manufacture specialty soaps and esters with unique solubility and surface tension properties.
