1. Product Introduction & Main Application
Arnico’s n-Hexane is a clear, colorless, highly volatile, linear aliphatic hydrocarbon obtained from crude oil distillation. Due to its exceptional and selective solvency for oils and fats, this substance is mainly used as the primary solvent in the process of extracting edible oils from oilseeds (such as soybeans, rapeseed, and sunflower) and in the production of adhesives and precision cleaning.

3. Features & Benefits
-
Unrivaled Selective Oil Solvent: Provides rapid and complete extraction of triglycerides from oilseeds without dissolving unwanted phospholipids and pigments.
-
Very Low Residue in Final Product: High volatility makes its recovery and separation from oil and meal easy and cost-effective.
-
Polymerization Purity (Polymer Grade): Free from benzene and sulfur, which is critical for Ziegler-Natta and metallocene catalysts in polyolefin production.
-
Chemical Stability: Does not react with oil, water, or most chemicals in the extraction process.
4. Industrial Applications
-
Food & Oilseed Crushing Industry: The primary solvent in the extraction of crude oil from oilseeds (vegetable oil plants).
-
Petrochemical & Polymer Industry: A solvent in the polymerization process for polyethylene and polypropylene.
-
Adhesive & Footwear Industry: A solvent in contact adhesive formulations and thinners.
-
Pharmaceutical Industry: An extraction solvent in the synthesis of certain APIs and herbal active ingredients.
5. Safety & Handling
-
MSDS (Material Safety Data Sheet): This liquid is highly flammable and hazardous. Its vapors are heavier than air, and inhalation causes neurological damage (neuropathy). The Arnico MSDS must be obtained without fail.
-
Storage Conditions: Store in nitrogen-blanketed tanks, in a completely cool environment, away from light, sparks, and static electricity. All equipment must be explosion-proof.
-
Personal Protective Equipment (PPE): The use of a full-face respirator with an AX filter, Viton gloves, and anti-static clothing is mandatory.
6. Quality Assurance & COA
Arnico n-Hexane shipments are accompanied by a Certificate of Analysis (COA) with a precise GC analysis, including benzene and sulfur content.
