nature : colorless, oily liquid, and industrial products, slightly pale yellow. Case-color gradually change to deep dark red, a slight odor similar camphor, menthol is heating odor. 8 ° C melting point, boiling point, 255-257 ° C, 129.4 ° C (1.6kPa), relative density (15.6 ° C) 1.098, 1.5712 refractive index (15.45 ° C), 1.5693 (20 ° C) . Do not dissolve in water, soluble in a variety of organic solvents.

preparation methods : a variety of routes. 1. Tetrahydronaphtho oxidation catalysts can choose to use a variety of oxidant and suitable for large-scale industrial production method is the use of chromium acetate and 2-methyl-5 - ethyl-pyridine complex catalyst, to air as the oxidant for continuous liquid atmospheric oxidation, the reaction temperature is 130 ° C, tetrahydro naphthalene and oxygen molar ratio of 0.6, stay 60-70min, tetrahydronaphtho one-way conversion rate up to 20% or more, generating 1-tetrahydro-1-one choice rate of about 90%, the main by-product of alcohol tetrahydro naphthalene. Vacuum distillation products by the available 98% of the 1,4-tetrahydrocannabinol. 2. Gamma-butyrolactone with benzene generated from condensation. Adopt-thiophene benzene raw materials, the yield up to 91% -96%. 3. Γ-butyl benzene ring of γ - benzene in acid phosphatase / P anhydride, more phosphoric acid, hydrofluoric acid or sulfuric acid concentration role, in 90 ° C ring of 1-naphthyl ketone tetrahydrocannabinol, the yield of 75-86%. 4. Γ - benzene ring of small chloride in anhydrous aluminum chloride or anhydrous stannic chloride dehydrochlorination presence in the ring of goods.

purposes : mainly for dehydrogenation A naphthol. Contraceptives 18 - levonorgestrel of intermediates. Also used as solvents and plastic softener. Rodenticide the pesticide intermediates. Its laced with insecticide and repellent effect.
