PRODUCT INTRODUCTION
description
n-Hexane is a chemical made from crude oil. Pure n-Hexane is a colorless liquid with a slightly disagreeable odor. It is highly flammable, and its vapors can be explosive. Puren-Hexane is used in laboratories. Most of then-Hexane used in industry is mixed with similar chemicals called solvents. The major use for solvents containing n-Hexane is to extract vegetable oils from crops such as soybeans. These solvents are also used as cleaning agents in the printing, textile, furniture, and shoemaking industries. Certain kinds of special glues used in the roofing and shoe and leather industries also contain n-Hexane. Several consumer products containn-Hexane, such as gasoline, quick-drying glues used in various hobbies, and rubber cement. .
