2,6-DIISOPROPYLNAPHTHALENE Chemical Properties,Usage,Production

Chemical Properties

beige crystalline platelets

Uses

2,6-Diisopropylnaphthalene, is a building block used for the synthesis of more complex compounds. 2,6-Diisopropylnaphthalene (2,6-DIPM) is also used in the manufacturing of pesticide products intended to prevent sprouting of stored potatoes.

Definition

ChEBI: 2,6-diisopropylnaphthalene is a member of the class of napthalenes that is naphthalene which is substituted by an isopropyl group at positions 2 and 6. It is a plant growth regulator which inhibits the sprouting of potatoes during storage. It has a role as a plant growth retardant and an agrochemical.

General Description

Clear yellowish brown liquid with a faint sweet odor.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

Vigorous reactions, sometimes amounting to explosions, can result from the contact between aromatic hydrocarbons, such as 2,6-DIISOPROPYLNAPHTHALENE, and strong oxidizing agents. They can react exothermically with bases and with diazo compounds. Substitution at the benzene nucleus occurs by halogenation (acid catalyst), nitration, sulfonation, and the Friedel-Crafts reaction. Friedel-Crafts acylation of naphthalene using benzoyl chloride, catalyzed by AlCl3, must be conducted above the melting point of the mixture, or the reaction may be violent [Clar, E. et al., Tetrahedron, 1974, 30, 3296].

Health Hazard

Exposure can cause irritation of eyes, nose and throat.

Fire Hazard

Special Hazards of Combustion Products: Irritating vapors and toxic gases, such as carbon dioxide and carbon monoxide, may be formed when involved in fire.

Flammability and Explosibility
