| Hazard Information | Back Directory | [General Description]
Clear yellowish brown liquid with a faint sweet odor. | [Reactivity Profile]
Vigorous reactions, sometimes amounting to explosions, can result from the contact between aromatic hydrocarbons, such as DIISOPROPYL NAPHTHALENE(24157-81-1), 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]. | [Air & Water Reactions]
Insoluble in water. | [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. | [Description]
A synthetic plant growth regulator used mainly on stored potatoes rather than in the open environment. Available data is limited. It is moderately soluble in water, has a low mammalian acute oral toxicity and not expected to cause serious, long-term negative health effects. It has a low to moderate toxicity to aquatic species. | [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. | [Production Methods]
The commercial production of 2,6-diisopropylnaphthalene involves a multi-step isopropylation and transalkylation process. Initially, naphthalene is isopropylated using propylene in the presence of an acid catalyst, producing a mixture of mono-, di-, and tri-isopropylnaphthalenes. This mixture undergoes transalkylation with a triisopropylnaphthalene-rich stream to redistribute isopropyl groups, enhancing the yield of the desired 2,6-isomer. The resulting mixture is then fractionally distilled to separate the mono-, di-, and tri-substituted products. The 2,6-diisopropylnaphthalene is isolated from the diisopropylnaphthalene fraction, while the mono- and tri-isopropylated fractions are recycled back into the process to improve efficiency and reduce waste | [Flammability and Explosibility]
