Descripción del producto
Naphthalene is a
white, volatile aromatic hydrocarbon with characteristic odor;
insoluble in water, somewhat soluble in methanol/ethanol, soluble
in organic solvents and very soluble in ether, chloroform, or
carbon disulfide. Commercially it is available in molten form or
in flaked form. It has the molecular structure of two fused or
condensed benzene rings sharing two adjacent carbon atoms; C*0H8.
Naphthalene is obtained from coal tar which is distilled in the
temperature range of **0 - **0 C and is treated with a sodium
hydroxide solution to remove phenols. Naphthalene is obtained by
the isolation from pyrolysis residue oils, olefin fractions, and
petroleum-derived fractions. The distribution capacity is
supposed to be about *0% coal-tar and *0% petroleum-derived
naphthalene in U.S.A. It is an important parent material to
produce numerous substitution products used in the manufacture of
dyes, insecticides, organic solvents and synthetic resins.
Phthalic anhydride is prepared by oxidizing naphthalene to be
used in the manufacture of dyes, resins, plasticizers, and
insecticides. Naphthalene sulfonate surfactants and dispersants,
however, have increased their market share significantly and are
expected to drive whatever growth there is for naphthalene.
Naphthalene is the major raw material for Carbaryl, used as a
general-purpose insecticide. Naphthalene is also used for moth
repellents, fungicides, lubricants, explosives, wood
preservatives, vermicides and hydronaphthalenes (tetralin,
decalin). Hydronaphthalenes are used for major raw material for
dyes, resins, plasticizers, and insecticides. They are also used
in reactive and process solvents, heat transfer fluid, dye
carrier, fuel additives, lubricants, ore flotation and
oilfield chemicals.
