Profile: Shandong Gude Chemistry Co., Ltd. is a provider of chemical products. We are certified to ISO 9001 quality management system. Our main products are industrial naphthalene, anthracene oil, absorber oil, crude carbolic acid, mid-temperature asphalt, mid-temperature modified asphalt, and modified asphalt. Our isoquinoline is applied to produce insecticides, antimalarial drugs, rubber vulcanization accelerator, and chemical reagents for determination of rare metals. Our industrial acenaphthene is a white or slightly yellow oblique needle-like crystal. It is slightly soluble in water, hot ether, hot benzene, toluene, acetic acid, chloroform, petroleum ether, and ethanol. It is flammable. After nitration, it can be made into nitroacenaphthene. After oxidation, it can be transformed into 1,8-naphthalic anhydride, and acenaphthequinone. It is applied in the synthesis of dye, polyester resin, and polyester fiber. After dehydrogenation, it is changed into acenaphthylene, so that it can be applied in the production of acenaphthylene resin, and fluorescence pigment.
