Appearance: Needle-like crystals ranging from white to pale yellow； Assay:99%min by HPLC； IR Identity: conform to standard； HNMR： conform to standard； carbon spectrum: conform to standard； Water by K. F.:0.5% max or as per the customer’s request； Loss on drying:0.5% max. or as per the customer’s request； =========================================================================== Uses: Naphthalene is mainly used as an intermediate in organic synthesis, with application areas including: Dyes and Pigments: It is an important raw material for producing 1,8-naphthalene dicarboxylic anhydride, which is used to synthesize dyes and fluorescent pigments; Plastics and Resins: It can be dehydrogenated to produce naphthalene, which is then used in the production of naphthalene resins; Agricultural Chemicals: It is used in the synthesis of plant growth hormones, insecticides, and fungicides; Others: It can be used as a reagent for determining aromatic aldehydes, an antioxidant for rubber and electric insulators, and a standard substance in laboratories. =============================================================================== Synthesis Routes: The industrial preparation and laboratory synthesis methods of anthracene mainly include the following: Industrial Preparation: It is extracted from coal tar. In high-temperature tar, the content of anthracene is about 1.2%-1.8%, and industrial-grade anthracene is obtained by distilling creosote and collecting the fraction at 270-280°C. Chemical Synthesis: Prepared by the reaction of 1,8-dibromomethyl naphthalene with phenyllithium. Synthesized from naphthalene and ethylene. In the laboratory, it can be synthesized through photochemical or laser-induced reactions of 1,8-di(substituted methyl)naphthalene. Uses : Organic synthesis raw material, which is used as a raw material for producing 1,8-naphthalene dicarboxylic anhydride. It can be used to synthesize dyes, polyester resins, polyester fibers; it can also be used to manufacture fluorescent pigments, pharmaceu Synonyms : 1,2-Dihydroacenaphthylene;1,8-Dihydroacenaphthalene;1,8-Ethylenenaphthalene;AI3-00128;CCRIS 5951;Ethylenenaphthalene;HSDB 2659;NSC 7657;Naphthyleneethylene;peri-Ethylenenaphthalene;Acenaphthylene, 1,2-dihydro-;ethene - naphthalene (1:1); Molecular Structure :
