Description

Benzene, Mono-C10-14-Alkyl Derivs., Fractionation Bottoms is a specialized alkylbenzene derivative, specifically the higher-boiling fraction obtained from the distillation of monoalkylbenzenes with C10-14 alkyl chains. This product matters as a versatile and cost-effective chemical intermediate, offering a defined hydrocarbon backbone for further synthesis. It is primarily needed by manufacturers in the surfactant, lubricant additive, and specialty chemical industries for producing detergents, emulsifiers, and functional fluids.

Application

• Surfactant Intermediate: A key raw material for the synthesis of linear alkylbenzene sulfonates (LAS), which are widely used in household and industrial detergent formulations.
• Lubricant & Grease Additive: Serves as a chemical building block for manufacturing additives that improve viscosity index, thermal stability, and detergency in lubricating oils and greases.
• Emulsifier Production: Used in the manufacture of nonionic and anionic emulsifiers for agricultural chemicals, coatings, and textile processing aids.
• Plasticizer & Polymer Modifier: Acts as an intermediate for plasticizers and modifiers that enhance the flexibility and processing of certain polymers.
• Oilfield Chemicals: Employed in the formulation of drilling fluid additives and demulsifiers for crude oil processing.
• Industrial Cleaning Compounds: A component in the production of heavy-duty industrial and institutional cleaning products.
