Description
n-Hexane (CAS 110-54-3, EC 203-777-6, formula C6H14) is a straight-chain aliphatic hydrocarbon solvent, also referenced under the trade names Esani and Hexanes and the NSC designation 68472. It carries no assigned E-code and is classified under HS code 29011000.
In edible oil processing, n-Hexane extracts lipids from oilseeds by dissolving triglycerides selectively, enabling high-yield separation before solvent recovery. In pharmaceutical manufacturing, it serves as a reaction solvent and recrystallization medium where low polarity is required to isolate non-polar intermediates cleanly. It also functions as a carrier solvent in adhesive and printing ink formulations.
n-Hexane is available in technical, food-grade, and high-purity analytical grades, with food-grade material produced in compliance with FCC specifications and REACH registration requirements. Procurement quantities typically range from drums to ISO tank deliveries. Buyers should confirm grade suitability against current REACH restrictions on hexane isomer content.
