Octanol, also known as n-octanol, is an organic compound that is colorless and transparent oily liquid with a strong greasy and citrus smell. It is immiscible with water, but miscible with ethanol. Octanol is mainly used to prepare dioctyl phthalate, dioctyl terephthalate, octyl acrylate, dioctyl azelaate, dioctyl sebacate and other products; Plasticizers, antifreeze agents, lubricants, extractants, dispersants, stabilizers, fragrances and other products are used in refined oil, plastics, coatings, printing and dyeing, food processing, cosmetics and other fields.

1 Octanol is mainly used to make phthalates and aliphatic dibasic acid ester plasticizers such as dioctyl phthalate, dioctyl azelaate and dioctyl sebacate, etc. It is used as the main plasticizer of plastics and cold-resistant auxiliary plasticizer, defoamer, dispersant, mineral processing agent and petroleum filler. It is also used in printing and dyeing, paint, film and so on.

2. Mainly used in the production of plasticizers, extractants, stabilizers, and intermediates for solvents and fragrances. In the field of plasticizers, octanol generally refers to 2-ethyl ethanol, which is a one-million-ton bulk raw material and is far more valuable than n-octanol in industry. Octanol itself is also used as a fragrance, blending rose, lily and other floral fragrances, as a soap fragrance. This product is an edible spice that is allowed to be used in my country's GB2760-86. Mainly used to prepare coconut, pineapple, peach, chocolate and citrus flavors, used as surfactants, solvents, defoaming agents, industrial additives, etc.
